[AI x Input Design 23] Tanaka-kun, the proposal became a "dictionary" after including all the requests from the three department managers

Character Introduction

Tanaka-kun
A serious and hardworking young employee. While he puts his heart into everything he is asked to do, he can be a bit clumsy, such as including every single piece of information. He is the protagonist who gradually grows through creating proposals while brainstorming with the AI Fairy.

• Manager Kuroda (Sales Manager)
  A manager who views things from a sales perspective. He is energetic and his demands are clear, but his instructions are quite vague. However, he hits the nail on the head regarding the essence of "whether it will be chosen by customers" and "whether it will sell." He is the type to keep giving Tanaka-kun new tasks.

• Manager Shiraki (Technical Manager)
  A calm and logical technical manager. He prioritizes whether the product can actually be made and whether it can be mass-produced. He plays the role of identifying the feasibility of the plan by making sharp points in a calm tone.

• Manager Hoshina (Quality Manager)
  A quality manager with a gentle demeanor. Despite appearing kind, his perspective on quality and assurance is very strict. He is like the final line of defense, determining whether it can truly be released to the world with peace of mind.

• Hayashi-san
  A senior colleague to Tanaka-kun. He is caring and has a great sense for the field. He acts as a coordinator who brings discussions back to a realistic direction while stopping Tanaka-kun from going off the rails and making witty remarks.

• Sato-san
  A calm, capable, and reliable person. She looks at what Tanaka-kun has created from a step back and provides hints for improvement. Her precise and cool-headed advice shines.

• Mayumi-san
  In a partner-like position to Hayashi-san, she has strong intuition and is the type to say exactly what she thinks. Although she sometimes reflects on being too blunt, she is genuinely happy about Tanaka-kun's growth this time and is in a slightly good mood. For some reason, she can converse naturally with the AI Fairy.

• AI Fairy
  A small AI support character who appears before Tanaka-kun. Contrary to her cute appearance, her observations are quite sharp. She is a partner who supports the creation of proposals as a brainstorming opponent, even while bickering with Tanaka-kun.

Tanaka-kun, the proposal became a "dictionary" after including all the requests from the three department managers

Learning through brainstorming with the AI Fairy: How to organize information overload and turn it into "documents that the other party can make decisions on"

The more information a proposal has, the better.

At least, that is what Tanaka-kun thought until a little while ago.

There is a lot of researched information.
There are numbers too.
The benefits are also written down.
Technical explanations are included as well.

In that case,the more detailed it is written, the better the proposal should be.

However—.

The Sales Manager, the Engineering Manager, and the Quality Assurance Manager.

When Tanaka-kun and the AI Fairy diligently incorporated all the information requested by the three managers—'I want this too' and 'This is also necessary'—a strange phenomenon occurred.

📚 The proposal kept getting thicker and thicker.

And to make matters worse, none of the content requested by the three managers was actually wrong.

Sales has things they need to know as Sales.

Engineering has things they must verify as Engineering.

Quality Assurance has things they cannot compromise on as Quality Assurance.

That is why he couldn't cut anything.

That is what he thought.

However, as Tanaka-kun continued to pack everything in, he eventually noticed something while looking at the document in progress.

If information is missing, the AI will struggle.

However—.

If there is too much information, both humans and AI will get lost.

While being pushed around by the unreasonable demands of the three managers, Tanaka-kun this time...

'Not what to write, but who is reading this to make what decision?'

He will take on the challenge of organizing information at a deeper level.

Of course.

This time, too, it was never going to end smoothly.

Chapter 1: Unexpected additional requests from the three department heads

"The framework is good, isn't it?"—was he praised this time?

Tanaka-kun stood in front of the conference room table, feeling a little nervous.

There were three people sitting in front of him.

Sales Department Head, Mr. Kuroda.

Technical Department Head, Mr. Shiraki.

And Quality Department Head, Mr. Hoshina.

In the center of the table lay the proposal that Tanaka-kun had worked so hard to compile.

However, this was not the final version.

Regarding the new product,

Is it worth considering as a market?

Is it likely to be technically feasible?

In terms of quality, is it likely to be able to proceed to the next verification?

It was the first-stage framework for the three departments to move on to the next stage.

Department Head Kuroda slowly turned the pages.

Flip.

Flip.

Tanaka-kun followed those fingertips with his eyes.

(How is it...?)

Department Manager Shiraki is also silently checking the technical pages.

Department Manager Hoshina is looking through the quality section with his usual calm expression.

No one is speaking.

Sweat begins to ooze from Tanaka-kun's back.

(I wish someone would say something...)

Before long.

Department Manager Kuroda placed the document on the desk.

"Tanaka"

"Yes!"

His voice was louder than he intended.

Department Manager Kuroda smiled slightly.

"It's not bad, is it?"

"...Eh?"

"As a framework, it's well-constructed."

Tanaka-kun blinked.

"Is that true?"

"I can understand the purpose of the project, and you've separated what we know now from what we need to confirm later."

Department Manager Shiraki also looked up from the document.

"It's also good that you didn't try to fill in all the numbers from the start."

"Yes"

"We are still in the first stage. There is no need to decide on the final equipment specifications here."

Department Manager Hoshina also smiles.

"Regarding quality, the items that have been confirmed and those that have not yet been confirmed are separated, aren't they?"

"Thank you very much!"

Tanaka-kun's face brightened up all at once.

✨ I did it.

I had argued with the AI Fairy many times.

There isn't enough information.

Don't fill in the parts you don't understand on your own.

I don't know what criteria the three department managers use to make decisions.

What even is a proposal in the first place?

I feel like I've taken quite a long detour.

Even so.

I was properly evaluated by the three of them.

Tanaka-kun clenched his fist slightly deep inside his chest.

(This time, it went well.)

Department Manager Kuroda leaned back in his chair.

"Well then, Tanaka."

"Yes!"

"Next, please provide a more detailed comparison with our competitors"

"Yes!"

Tanaka-kun replied cheerfully.

At least, at that time.

"This too," "that too," and "the other thing too."

Department Manager Kuroda continued.

"I want to see the reasons for choosing our product compared to the competitor's product."

Tanaka-kun takes notes.

📝 Competitor comparison

"Let's also make the benefits from the customer's perspective a bit more concrete."

📝 Customer benefits

"Also, please include the weak points as well."

Tanaka-kun's pen stopped for a moment.

"The weak points?"

"Yes. If you only write about the good things, they won't be able to make a decision, right?"

"I see..."

📝 Sales disadvantages

"I'd also like to see the estimated price."

📝 Price

"The market size also--"

Just then.

"Wait."

Department Manager Shiraki interrupted.

"Don't just increase the sales talk."

Department Manager Kuroda looked to the side.

"What is it?"

"If you're going that far, have them add the technical side as well."

Tanaka-kun's pen tip turned toward Department Manager Shiraki.

"To what extent can the current equipment handle it?"

📝 Scope of support with existing equipment

"If new equipment is needed, make sure that's clear too."

📝 Additional equipment

"And then, the production capacity in the case of mass production."

📝 Production capacity

"Just because one prototype was made doesn't mean it can be mass-produced. It's better to organize the process issues as well."

📝 Issues during mass production

Tanaka-kun's notepad was rapidly filling up with text.

(Huh...?)

Then, a gentle voice was heard from the side.

"In that case, could I ask for the quality side as well?"

Tanaka-kun slowly looks at Department Manager Hoshina.

Department Manager Hoshina was smiling.

😊

Why is that?

Even though he is smiling, it is a little scary.

"...What would that be?"

"I would like to confirm the quality variations during mass production."

📝 Variations during mass production

"And also, to what extent we can guarantee it at this point."

📝 Scope of guarantee

"It would be helpful if you could also organize the necessary tests."

📝 Necessary tests

"There are also inspection methods."

📝 Inspection methods

Tanaka-kun's pen stopped.

Department Manager Kuroda says.

Please also organize the possibilities of customers not buying.

Department Manager Shiraki continues.

I also want the supply capacity in case the equipment stops.

Department Manager Hoshina also continues.

It would also be good to have the assumed defects.

Tanaka-kun looks at his notepad.

It is packed.

Next, he looks at the three of them.

And then, he looks at his notepad once more.

😨

Um...

Department Manager Kuroda.

Hmm?

Tanaka-kun lifted his notepad with both hands.

The three department managers looked at each other.

Department Manager Kuroda answers easily.

Iam counting on you.

............

Department Manager Shiraki crossed his arms.

"Well, try organizing it once"

"............"

Department Manager Hoshina had his usual gentle smile.

"I'm looking forward to it"

"............Yes"

The sense of accomplishment he had felt in his chest just moments ago had vanished somewhere.

Tanaka-kun clutched the proposal.

He also held the notepad filled with a massive amount of additional items.

And then.

🚶‍♂️ trudge, trudge...

With an indescribable gait, he left the conference room.

After the door closed, the three of them—

Click.

The door closed.

The conference room fell silent.

A few seconds later.

Department Manager Kuroda's mouth,

a smirk.

curled upward.

Manager Shiraki glances over.

"...You."

"What is it?"

"You're enjoying this, aren't you?"

"What are you talking about?"

"The look on your face just now."

Manager Hoshina is also chuckling.

"We did ask for quite a lot, after all."

Manager Kuroda looks at the door through which Tanaka-kun just left.

"Well then."

He crosses his arms.

"I wonder what he'll come back with."

Manager Shiraki replied.

"If he just stuffs everything in as requested and brings it back, he's still got a long way to go."

"But Tanaka is serious when he's on the job, right?"

"Yeah."

Manager Shiraki nodded.

"He follows procedures properly. He doesn't take reckless risks regarding safety. He's not the type to pretend he understands things he doesn't."

Manager Hoshina slowly opens his mouth.

"Though he does make mistakes."

"Hey."

Department Manager Kuroda laughs.

Department Manager Hoshinaalso continued while still smiling.

"But he is not the type of person to leave things as they are after failing."

I think for a moment.

"If I think something is wrong, I go back. If I don't understand, I ask. If that still doesn't work, I start over again."

Department Manager Kurodanods slightly.

"That's why it's interesting."

Department Manager Shiraki exhales as if exasperated.

"Your bad habit has started again."

"What is it?"

"It's that tendency of yours to throw tasks at people and see how they handle them."

Department Manager Kuroda shows no sign of remorse.

"Some people grow better when you give them a challenge, don't they?"

Department Manager Shiraki replies.

"Some people are better off being taught the basics one by one and building confidence before they grow."

Department Manager Hoshina joins in.

"Some people find their own way of doing things while consulting with their colleagues, too."

The three of them turn their gazes toward the closed door.

Department Manager Kuroda says.

"That Tanaka guy is--"

He paused for a moment.

Then, he smiled with a wicked look again.

😏

"Well, you'll see soon enough."

Department Manager Shiraki, too.

Department Manager Hoshina, too.

They were both smiling, looking somewhat amused.

Meanwhile, Tanaka-kun--.

Holding the massive amount of requests handed to him by the three of them,

he still hadn't realized that he was about to start creating something incredibly thick.

Chapter 2: Fairy-chan, overwhelmed by too much information

This time, it's not a lack of information. If anything, there's too much.

Returning to his workspace, Tanaka-kun placed the proposal and his notepad on the desk.

Thud.

"............"

He looked at the notepad.

Things requested by Department Manager Kuroda.

Things requested by Department Manager Shiraki.

What Department Manager Hoshina asked for.

The page is filled with text.

Tanaka-kun sat in his chair and stared at it for a while.

“...Well”

He pulled himself together.

“It's better than not having enough information, I suppose.”

The last time was a disaster.

He had some information about Department Manager Kuroda.

He was also able to hear about Department Manager Shiraki's work content and way of thinking.

However, regarding Department Manager Hoshina,

“Quality Manager”

he knew almost nothing other than that title.

In that state, he asked the AI Fairy to,

“create a proposal that all three would approve of”

and it turned into a huge fight.

Tanaka-kun remembered that time.

“This time is different.”

The AI Fairy that appeared next to the desk turned around.

“What is?”

Tanaka-kun proudly held up his notepad.

"Take a look."

The fairy peers in.

📝

Market size.

Competitor comparison.

Customer benefits.

Estimated price.

Existing equipment.

Additional equipment.

Production capacity.

Mass production challenges.

Quality variations.

Warranty coverage.

Required testing.

Inspection methods.

Anticipated defects.

Supply capacity during equipment downtime.

There's still more.

The fairy's eyes sparkled.

✨

"Tanaka-san!"

"Yeah"

"I have information this time!"

"Right?"

"I have a lot!"

"I thought so."

Tanaka-kun puffed out his chest.

The fairy also happily raised both hands.

"Yes!"

Tanaka-kun turned back to his computer.

"Alright, let's put everything in and create the proposal."

"Understood!"

The two of them began working energetically.

At least, until this point.

Huh? The proposal is getting bigger and bigger.

It started off smoothly.

Tanaka-kun inputs the information.

The fairy organizes it.

"Competitive Comparison"

I'll add it to the sales items.

Customer benefits.

This is also sales-related.

Estimated price.

I'll add it!

It's moving along smoothly.

Tanaka-kun is also in a good mood.

Unlike last time,

"There is no information!"

"I don't know!"

"Only Tanaka-san knows that!"

is not being said.

😊 The little fairy is being obedient today.

Tanaka-kun continues to input more.

"Next, the one requested by Department Manager Shiraki"

"Yes!"

Existing equipment.

Additional equipment.

Production capacity.

Process issues.

Supply capacity during equipment downtime.

Items appeared one after another behind the fairy.

[Sales]

[Market]

[Customer]

[Competition]

[Price]

[Technology]

[Equipment]

[Process]

[Production Capacity]

Tanaka-kun tilted his head slightly.

"...That's quite a lot."

The fairy didn't seem to mind.

"There's more!"

"Ah. Quality, right."

Now, he started adding the content requested by Department Manager Hoshina.

Quality standards.

Variations during mass production.

Warranty scope.

Required tests.

Inspection methods.

Assumed defects.

Unverified performance.

Additional verification items.

The display keeps growing.

[Quality]

[Warranty]

[Inspection]

[Testing]

[Defects]

[Variations]

[Unconfirmed items]

Tanaka-kun pulled back from the screen a little.

"............"

The fairy is still continuing the work.

"Tanaka-san, which one is next?"

"Wait a second."

"Yes?"

"This one..."

Tanaka-kun pointed at the screen.

"Isn't this quite a lot?"

The fairy also turned around.

"Yes, it is."

"We're not done yet, are we?"

"No."

"............"

Tanaka-kun looked at his notepad.

There was still more left.

"Shall we continue?"

"There are still things requested by the department managers."

"I suppose so..."

The two of them began working again.

The information meter, surprisingly exceeding 100%

Inputting.

Organizing.

Adding.

Inputting again.

The information meter displayed behind the fairy kept going up and up.

📊

[Information volume 65%]

[Information volume 78%]

[Information volume 91%]

Tanaka-kun laughs.

"It's almost 100% now."

The little fairy also turns around happily.

"There is plenty of information this time!"

[Information volume 100%]

✨

"Oh!"

Tanaka-kun claps his hands lightly.

"It reached 100%!"

The little fairy is also delighted.

"There is sufficient information!"

However.

Ping.

[Information volume 112%]

"...Hmm?"

Ping.

[Information volume 137%]

Tanaka-kun stares at the screen.

"Fairy-chan"

"Yes"

"It's over 100%"

"...Yes"

Ping.

[Information density 168%]

Fairy-chan's smile vanished.

😐

"Tanaka-san"

"Yeah"

"Are you still going to add more?"

"There's still more"

"............"

Ping.

[Information density 203%]

Fairy-chan's face twitched.

😵‍💫

"W-wait a second!"

"What's wrong?"

There is too much information!

Huh?

Tanaka-kun asked back, taken by surprise.

Too much?

Yes!

A warning display appears behind the fairy.

⚠️ [Information Overload]

⚠️ [Purpose is buried]

⚠️ [Priority is unclear]

⚠️ [Please confirm if this is necessary for the current decision]

Tanaka-kun's eyes went wide.

The fairy waved both hands.

Just because I said that doesn't mean I told you to include everything!

Tanaka-kunretorted without backing down.

But I was asked for all of this by the department managers!

I understand that!

Then I have to include it, don't I!

The one who decides whether to include it or not is you, Tanaka-san!!

Me again!?

It's Tanaka-san again!

😠💢

An unpleasant atmosphere began to drift between the two of them once again.

Tanaka-kun crossed his arms.

Then you choose, Fairy-chan.

Based on what criteria?

Whatever seems necessary!

Necessary for whom?

The three department managers!

All three of them need different things!

Then all of it!

{The result of doing that is what you see now!}

............

Tanaka-kun fell silent.

Fairy-chan also fell silent.

Only the screen,

⚠️[OOO...!]

⚠️[△△△△...!!]

⚠️[OXOXXX...!!!?]

continued to issue warnings.

Since everything is correct, it's even harder to cut anything out

Tanaka-kun reviewed the content requested by the three of them once more.

Department Manager Kuroda's requirements.

• Comparison with competitors.

• Customer benefits.

• Market size.

• Price.

• Sales weaknesses.

They certainly seem necessary.

Next, Department Manager Shiroki.

• Equipment.

• Processes.

• Production capacity.

• Issues during mass production.

• Supply capacity during equipment downtime.

These also seem necessary.

And finally, Department Manager Hoshina.

• Quality standards.

• Warranty coverage.

• Testing.

• Inspection method.

• Variability.

• Expected defects.

...This also seems necessary.

"Fairy-chan"

"Yes"

"Not a single person is saying anything strange."

"That's true."

"That's why it's a problem."

Fairy-chan also thinks for a moment.

"All three of them are providing information that is necessary from their respective positions."

"Right?"

"Yes."

Tanaka-kun scratched his head.

If someone had said,

"Include today's weather in the proposal,"

it would be easy.

I could decide that such a thing is unnecessary.

However, this time the requests are different.

• Necessary as the Sales Manager.

• Necessary as the Technical Department Head.

• Necessary as the Quality Department Head.

Everything is, in its own way, correct.

That is why Tanaka-kun

thought he had to include everything.

That is what he thought.

The fairy gazes at the massive number of items displayed.

"Tanaka-san"

"Hmm?"

"Just because the information is correct, does it really need to be put in the same place?"

"............"

Tanaka-kun could not answer.

He still did not understand the meaning of that.

Looking at the half-finished proposal, Tanaka-kun froze.

Even so, the two of them continued the work for the time being.

After all, they had gone to the trouble of getting information from the three of them.

They wouldn't know until they tried to give it some form first.

Sales.

Technical.

Quality.

Market.

Facilities.

Warranty.

Comparison.

Risk.

Testing.

Price.

Supply.

Inspection.

Adding chapters one by one.

The number of pages keeps increasing too.

10 pages.

15 pages.

20 pages.

And it keeps growing.

Tanaka-kun had gone silent.

The little fairy was also becoming less talkative.

"Next..."

"Yes..."

"When equipment is stopped..."

"I'll add it..."

"Next... quality..."

"Yes..."

And then.

A while later.

Tanaka-kun stopped moving his hands.

"Fairy-chan."

"Yes?"

"Let's take a look from the beginning."

The two of them opened the proposal that was in the middle of being completed.

Tanaka-kun scrolled down.

Market.

Scroll.

Customer.

Scroll.

Competition.

Scroll.

Price.

Scroll.

Technology.

Scroll.

Facilities.

Scroll.

Production capacity.

Scroll.

Quality.

Scroll.

Testing.

Scroll.

Warranty.

Scroll.

It still continues.

Tanaka-kun's finger stopped.

"............"

The fairy is also silent.

Tanaka-kun looked over it again from the top.

And then.

He slowly opened his mouth.

The fairy looks at the screen.

I look at Tanaka-kun.

I look at the screen again.

““…………””

I don't deny it.

“Fairy-chan?”

“……Yes.”

“Say something.”

“It has become a very detailed document.”

“That's one way to put it!”

Fairy-chan makes a troubled face.

😥

“But…… Tanaka-san.”

“Yeah?”

“Do you think the three department managers will read this from beginning to end?”

Tanaka-kun freezes.

“…………”

He hadn't thought that far ahead.

He had only been thinking about including information.

He had only been thinking about not leaving out any of the requested content.

Who is going to read it?

What are you reading this to decide?

That perspective had disappeared before he knew it.

Tanaka-kun sat back deeply into his chair.

“...Did I do it again?”

The fairy tilted her head.

“Do what?”

Tanaka-kun stared at the screen packed with a massive amount of information.

At that moment.

A voice he felt he had heard somewhere before crossed the back of his mind.

“...Ah.”

The fairy looked at Tanaka-kun.

“Tanaka-san?”

Tanaka-kun placed his hand on his forehead.

“This... I feel like I've done something similar before.”

Faced with the massive amount of information,

the faces of Hayashi-san and Sato-san began to float into Tanaka-kun's mind.

Chapter 3: “Don't include everything” — The words he was told before cross his mind

Are you doing the same thing again?

Tanaka-kun stood motionless, staring at the unfinished proposal.

• Market.

• Competition.

• Customers.

• Price.

• Facilities.

• Processes.

• Production capacity.

• Quality.

• Testing.

• Warranty.

Risks.

Even if you turn the pages.

Even if you scroll.

It never ends.

📚 Anyway, there is plenty of information.

It was the exact opposite of last time.

Last time,

"There wasn't enough information."

I don't know what kind of person Manager Hoshina uses to make decisions.

I argued about that endlessly with the fairy.

However, this time,

there is too much information.

Tanaka-kun leaned back in his chair.

...What should I do?

The fairy was also staring at the long list of items.

Should we cut them?

Which ones?

...

Look.

Tanaka-kun held up his notepad.

Everything here is what the managers said.

Yes.

Is it okay for me to just cut them on my own?

The fairy also looked troubled.

😥

We need a standard to decide that.

A standard, huh...

Tanaka-kun crossed his arms.

That was when it happened.

Suddenly.

A voice I had heard somewhere long ago popped into my head.

Tanaka-kun's eyebrows twitched.

......

This time, another voice overlapped.

...Ah.

The fairy turned around.

What's wrong?

No... nothing.

Tanaka-kun pressed his forehead.

I feel like I've been told something similar before.

By whom?

By Hayashi-san, or maybe Sato-san...

The fairy tilted her head.

What were you told?

Tanaka-kun thought for a moment.

If I recall...

Hayashi-san's exasperated face floats into my mind.

"Just because you went to the trouble of researching it doesn't mean you should include everything."

Then, Sato-san's calm voice follows.

"What is it that the reader actually needs?"

Tanaka-kun looks at the proposal in front of him.

"............"

The fairy looks at the screen with him.

Tanaka-kun mutters quietly.

"I was trying to include everything again, wasn't I?"

The fairy,

"Yes."

replies immediately.

Tanaka-kun turns around.

"You could at least deny it a little, you know."

"It's a fact"

"Fairy-chan, haven't you been a bit harsh lately?"

"Because Tanaka-san keeps doing the same thing"

"............"

I can't argue with that.

This time, I managed to stop myself before anyone else had to tell me.

Tanaka-kun reviewed the proposal from the beginning once more.

In the past, he might have.

• Researched a lot.

• Written a lot.

• Increased the amount of information.

And so,

"Alright, it's more detailed now."

That might have been where it ended.

And he would have taken it straight to his boss.

But this time was different.

It wasn't finished yet.

He hadn't submitted it to anyone either.

It wasn't that Hayashi-san or Sato-san,

"This is no good."

had told him that.

Tanaka-kun himself,

"Something feels off."

stopped midway through.

After thinking for a moment, Tanaka-kun spoke to the fairy.

"Hey."

Yes.

This time, you see...

Yes.

Rather than getting grilled by Hayashi-san and the others again after everything is finished...

He pauses for a moment.

You realized that a bit earlier, didn't you?

The fairy looks at Tanaka-kun.

😐

"...I suppose so."

What's with that look?

"I am currently assessing whether this can be called significant growth."

You should just praise me normally for that!

The fairy smiles a little.

😊

But, I did notice it faster than before.

Right?

Yes.

Tanaka-kun also smiles a little.

Just a tiny bit.

He has become able to notice the discomfort himself.

Even just that is different from before.

Why don't you try sorting them by "who will read it"?

Tanaka-kun laid out the requests handed to him by the three department managers on his desk.

"Let's reorganize this once."

"Yes."

The little fairy also regained a bit of her energy.

Tanaka-kun first looks at Department Manager Kuroda's requests.

• Competitor comparison.

• Customer benefits.

• Price.

• Market size.

• Sales disadvantages.

"This is... the part that Department Manager Kuroda specifically wants to see, right?"

"He is the Sales Manager, after all."

Next, Department Manager Shiraki.

• Existing equipment.

• Additional equipment.

• Production capacity.

• Processes.

• Supply capacity during equipment downtime.

"This is technology."

"Yes."

And then there was Department Manager Hoshina.

• Quality standards.

• Variations during mass production.

• Scope of warranty.

• Testing.

• Inspection methods.

• Assumed defects.

"This is quality."

"That's right."

Tanaka-kun looked at the three items.

"............"

The fairy asked.

"Did you notice something?"

"No."

Tanaka-kun pointed to Department Manager Kuroda's memo.

"I was just wondering if Department Manager Kuroda really needs all these fine details about the quality testing."

"I see."

"Of course, I think it's good to know about them."

Yes.

But that's not what Department Manager Kuroda really wants to know, is it?

The fairy's expression changed.

✨

Then, should we change the information shown depending on who is reading it?

Maybe.

Maybe?

That's the part... I still don't know.

Tanaka-kun scratched his head.

But just because all three of them are reading the same proposal, it doesn't mean we need to show them the same amount of information, right?

The fairy thought for a moment.

Show Department Manager Kuroda the parts necessary for sales decisions in detail.

Yeah.

Show Department Manager Shiraki the parts necessary for technical decisions in detail.

Exactly.

Show Department Manager Hoshina the parts necessary for quality decisions in detail.

Tanaka-kun snapped his fingers.

👉✨

That's it.

The fairy smiled.

"Then, shall we make three versions?"

Tanaka-kun's face froze.

"............Three versions?"

"Yes."

"The proposal?"

"Yes."

"For all three of them?"

"Yes."

Tanaka-kun sank deep into his chair.

😨

"You just increased the workload......"

"It's to make it easier to understand!"

"My job just became harder to understand."

Not the "information they want," but the "information they need to make a decision."

Tanaka-kun thought while looking at the notes for the three people.

"But still."

"Yes."

"If we include everything for each person, won't it just end up being thick again?"

The fairy stopped.

"......It will, won't it."

"I know, right."

It felt like I was about to end up back where I started.

For Manager Kuroda.

For Manager Shiroki.

For Manager Hoshina.

Even if I split it into three volumes, if I include everything they asked for, each one will end up thick anyway.

Tanaka-kun rolled his pencil between his fingertips.

"Well then..."

He thought for a while.

"Don't we need to narrow it down even further, even among the things the managers said they wanted?"

"What criteria should we use?"

That question again.

Tanaka-kun furrowed his brow.

"Things they want..."

"Yes."

"Important things..."

"Yes."

"Hmm..."

Everything was vague.

To Manager Kuroda,

"Which of these are important?"

If you ask that, they will likely say everything is important.

Department Manager Shiraki, too.

Department Manager Hoshina, too.

Each of them is making requests because they need them for their own work.

Tanaka-kun was silent for a while.

And then.

Suddenly, he remembered the previous proposal.

From the three of them,

what are we getting approval for?

It is not approval for final sales.

It is not quality assurance for the finished product either.

What we are seeking this time is,

can we proceed to the next stage of consideration?

That was the judgment we needed.

Tanaka-kun looks up.

"Fairy-chan"

"Yes"

"How about asking it this way?"

"What kind of way?"

Tanaka-kun writes a sentence in his notepad.

📝

Then he reads it aloud.

The fairy's eyes widen.

...I see.

Not everything they want.

Yes.

Not everything that is important either.

Yes.

The things that are absolutely essential for that person to make a decision this time.

A new display appears behind the fairy.

✨ [Essential information for decision-making]

✨ [Information that is useful if available]

✨ [Information needed for the next stage]

Tanaka-kun looks at the screen.

Exactly.

He points at it.

Something like this.

The fairy turns back, looking happy.

So, it's not about discarding information, but about separating when it's needed.

...Ah.

This time, it was Tanaka-kun who froze.

I see.

It's not that it's unnecessary.

• The price is also necessary.

• The equipment specifications are also necessary.

• Quality assurance is also necessary.

• The test results are also necessary.

However,

it's not that everything is needed right now.

Tanaka-kun was beginning to understand little by little.

Trying to find the 'non-negotiables' of the three managers

Tanaka-kun and the Fairy-chan looked over the three managers' requests once again.

First, Department Manager Kuroda.

'In sales, what is it that you can't move forward without knowing...'

Fairy-chan lined up the candidates.

[Does the customer really need this?]

[Is there value in proposing this compared to the competition?]

[Is there enough demand to consider this as a business?]

[Price]

[Market Size]

[Competitor Details]

Tanaka-kun shakes his head.

"Still too many."

"Then should we narrow it down further?"

"Yeah."

Tanaka-kun thinks.

"What is the thing that bothers Manager Kuroda the most?"

"Is it not being able to make proposals to clients?"

"That's right."

Next is Manager Shiroki.

[Is it technically feasible?]

[Is there a prospect for mass production?]

[Equipment capacity]

[Required processes]

[Additional equipment]

[Maintenance conditions]

"Manager Shiroki is..."

Tanaka-kun thought for a moment.

"The most troublesome thing is saying you can build something when you can't."

"Yes."

And Department Manager Hoshina.

[Significant Quality Risks]

[Scope of Guarantee]

[Quality Standards]

[Test Items]

[Variations]

[Inspection Methods]

Tanaka-kun pictures Department Manager Hoshina's calm face.

"Department Manager Hoshina is..."

"Yes."

"Even if you can build it, the most troublesome thing is releasing something whose quality cannot be guaranteed."

The fairy nodded.

All three of them,

need different information.

That was not merely a matter of preference.

It was because the areas they are responsible for are different.

What was learned last time is beginning to connect to this work, little by little.

Tanaka-kun lined up the three memos.

Then

Yes

First, let's try making one for each person

The fairy answered cheerfully.

Yes!

Tanaka-kun placed Department Manager Kuroda's memo on top.

First is Department Manager Kuroda, then

That's for the Sales Manager, right?

Things to compare

Yes

Demerits

Yes

And then, the material for Department Manager Kuroda to make his final decision

Three frames appeared behind the fairy.

📊 [Comparison]

⚠️ [Demerits]

✅ [Decision Material]

Tanaka-kun rolled up his sleeves.

Alright

The fairy also raised both hands.

"Let's do it!"

The two of them didn't know yet.

That the method they started at this time,

"creating one carefully for each department manager"

—would end up doing this.

It would exhaust them both incredibly after this.

Chapter 4: First, let's create one carefully for Department Manager Kuroda

The first one takes longer than expected

Tanaka-kun laid out the requests he received from Department Manager Kuroda on his desk.

Competitor comparison.

Customer benefits.

Market size.

Estimated price.

Sales disadvantages.

And the materials necessary for Department Manager Kuroda to make a decision at this stage.

The fairy was standing next to him with her arms crossed.

"Then, let's start with the one for Department Manager Kuroda."

"Yeah."

Tanaka-kun also sat back down in his chair.

"First... it's the comparison."

A display appears behind the fairy.

📊 [Comparison]

Tanaka-kun thought for a moment.

"Comparison with competing products"

"Yes"

"Price comparison"

"Yes"

"I wonder if we also need a comparison with the methods customers are currently using."

"I'll add it to the list."

"What about a comparison of market size..."

The fairy stops.

"What are you comparing it to?"

"Huh?"

"Isn't market size itself more of a factor for judging marketability rather than a comparison?"

Tanaka-kun also stops.

"...I see."

He adds one thing.

He removes one thing.

He thinks again.

"Then, should we focus on the differences from competing products?"

Since Manager Kuroda is the Sales Manager, I think the differences that can be explained to customers are important.

Then, besides performance, we also need the benefits for the user, right?

Yes.

Tanaka-kun adds a note.

📝 Differences from competing products

📝 Benefits the customer gains

📝 Proposed value compared to existing methods

...Something like this?

Looks good.

Tanaka-kun smiled a little.

Oh, it's going well, isn't it?

The fairy also smiles.

😊

It's only the comparison part for now, though.

Are you saying that now?

Manager Kuroda cannot make a decision based on benefits alone.

Next was the disadvantages.

⚠️ [Disadvantages]

Tanaka-kun pauses for a moment.

I wonder what I should write here.

Isn't that the weak point of the product?

That's true, but...

Tanaka-kun furrowed his brow.

Considering I have to show this to Department Manager Kuroda...

The fairy waits.

It's not just about simply listing the bad points, is it?

What do you mean by that?

Things that are problematic from a sales perspective.

The fairy's expression changes.

✨

I see.

Tanaka-kun puts his thoughts into words little by little.

For example, the price is higher than the competition.

Yes.

The performance is good, but it's hard to explain to customers.

Yes.

The benefits of implementing it are hard to understand.

Yes.

There's also a possibility that the market is smaller than expected.

The fairy organizes the points.

⚠️ Possibility of being at a disadvantage in price competition

⚠️ Possibility that the value is not easily conveyed to the customer

⚠️ Possibility that demand is lower than expected

⚠️ Possibility that the difference from competitors is small

Tanaka-kun looked at the screen.

"......Is this what it means?"

"These are the points that Department Manager Kuroda is worried about from a sales perspective."

"Yes."

Tanaka-kun thought for a moment before speaking.

"If I only write the good things, it becomes an advertisement, not a proposal."

The fairy nodded.

"Because it is a document for them to make a decision."

Tanaka-kun fell silent for a moment there.

Last time.

He remembered what the fairy had told him.

Instead of showing only convenient information to get approval, you also need to present bad information or unconfirmed items if necessary.

He was beginning to understand the meaning of that little by little.

The fairy smiled.

"Yes."

...It's starting to look like a proposal.

I've been making a proposal from the start.

I know, but still.

The last part is "what you want them to decide."

Tanaka-kun looks at the next box.

✅ [Decision-making criteria]

This is the hardest part.

Is it?

Well, for comparisons and disadvantages, you just need to organize the information, but...

Tanaka-kun thinks for a moment.

What does "decision-making criteria" actually mean?

The fairy answers.

It's the material for Department Manager Kuroda to decide whether to proceed at this stage.

I understand that.

Then, what is Department Manager Kuroda going to decide?

Tanaka-kun falls silent.

......

The fairy waits as well.

Tanaka-kun remembered the previous conversation.

Department Manager Kuroda looks to see if there is value in proposing it to the client.

Is it worth continuing to consider as a market?

Can we move to the next stage as a sales department?

"...It's not about whether it will sell, is it?"

The fairy nodded.

"It is not yet the stage to decide on final sales."

"Then"

Tanaka-kun searched for the right words.

"Is there a possibility that we can propose this to customers?"

"Yes."

"Is it worth investigating in more detail as a market?"

"Yes."

"Does it have enough unique features to consider compared to competitors?"

"Yes."

The organized items lined up behind the fairy.

✅ Is it worth proposing to customers?

✅ Is it worth continuing market verification?

✅ Is differentiation from competitors likely to be established?

✅ Can we move to the next stage of consideration as a sales department?

Tanaka-kun crossed his arms.

"...With this, I can see why Department Manager Kuroda would want to look at it."

"Yes."

"Look at the comparison."

"Yes."

"Look at the disadvantages too."

"Yes."

"Based on that, we will decide whether to proceed."

"That's right."

Tanaka-kun nodded deeply.

"Alright."

It takes a lot of brainpower just to decide on one item.

However.

From here on, it was a long process.

"Is this comparison really necessary?"

"If Department Manager Kuroda is going to make the decision, I think it's better to keep it."

"What about this one?"

"It might be fine as a common section."

"Then I'll move it."

A little while later.

"Is this a disadvantage?"

"It's also related to the decision-making criteria."

"Which one should I put it in?"

"It makes sense either way."

"That's exactly what I'm struggling with."

Furthermore.

"What is the size of this market?"

"It's important."

"Is it just for Department Manager Kuroda?"

"If all three of them need to know the scale of the project, it can be common to all."

"Then let's make it common."

"However, it's fine to make it more detailed for Department Manager Kuroda."

"...Which one is it?"

😵‍💫

The little fairy also looks a bit troubled.

"It depends on how you want to present it, Tanaka-san."

"Me again..."

Checking it over and over.

Rearranging it over and over.

Reverting what was once decided.

Thinking about it again.

Rather than gathering the information itself,

Deciding where to put things is the hardest part.

Tanaka-kun gradually became less talkative.

...this

Yes

Keep it

Understood

This one

Yes

Common

I'll move it

This...

Yes

Wait a second

Tanaka-kun holds his forehead.

It feels like I'm swapping things around in my head over and over again.

The fairy says.

Because you are comparing, judging, and comparing again.

It's strange how tiring this is, even though I'm just writing text.

We are still on Department Manager Kuroda's section.

Tanaka-kun looks at the fairy.

"Don't say that now."

Finally, the version for Department Manager Kuroda is complete.

A while later.

Behind the fairy, three organized frames appeared.

📊 [For Dept. Manager Kuroda: Comparison]

• Differences from competing products

• Customer benefits compared to existing methods

• Differentiation points to explain to customers

⚠️ [For Dept. Manager Kuroda: Disadvantages]

• Possibility of being at a price disadvantage

• Possibility that value is difficult to convey to customers

• Possibility of low projected demand

• Possibility that the difference from competitors is insufficient

✅ [For Dept. Manager Kuroda: Decision Criteria]

• Is there value in proposing this to the customer?

• Is there value in continuing market verification?

• Can we proceed to the next stage of consideration as sales?

Tanaka-kun stared at the screen.

Compared to the massive amount of information that was lined up at first, it is quite small.

But.

The parts that Department Manager Kuroda needs to look at have actually become easier to understand.

"...I suppose this is fine."

The fairy also checks it.

"I also organized the parts that were overlapping with the common information."

"Yeah."

"The parts that Department Manager Kuroda specifically needs to see remain."

"Yeah."

"It includes not only the benefits but also the drawbacks."

"Yeah."

"The content you want him to decide on this time is also clear."

Tanaka-kun let out a big sigh.

"............"

And then.

He leaned back into the backrest of his chair.

The fairy also raises both hands.

✨

"It's complete!"

Tanaka-kun smiled a little.

"Man, that took quite a while."

It's the first one, after all.

But, one is done.

Yes.

Tanaka-kun looked over the proposal for Department Manager Kuroda.

He felt a sense of accomplishment.

The proposal that had been on the verge of becoming a "dictionary" just a moment ago,

had changed its form significantly just by deciding on a single reader.

Tanaka-kun nodded with satisfaction.

Alright.

The little fairy also answered energetically.

Yes!

Tanaka-kun picked up the next memo.

Department Manager Shiraki.

Technology.

Equipment.

Process.

Production capacity.

Tanaka-kun rolled up his sleeves.

Shall we go to the next one?

Yes!

Both of them still had a little energy left.

The second time—wait? That was much faster than before.

Tanaka-kun spread out Department Manager Shiraki's notes.

So, what was first again?

The fairy answered immediately.

We will separate the common parts.

Ah, that's right.

After that, the comparison that Department Manager Shiraki specifically needs.

Next, the disadvantages.

Finally, the decision-making material.

Tanaka-kun stopped.

...Huh?

What's wrong?

The steps have already appeared.

The fairy smiled.

😊

Because we've done it once already.

Tanaka-kun also smiled a little.

I see.

For Manager Kuroda's version,

What should be categorized and how?

What should be compared?

What are the disadvantages?

What constitutes the basis for judgment?

We used to think about those things together.

But it's different now.

I already know the steps for organizing things.

Even if the content changes from sales to technical,

the order of operations remains the same.

Tanaka-kun looks at Manager Shiraki's requirements.

"Then, comparison."

The fairy suggests candidates.

📊 Comparison with handling it using existing equipment

📊 Comparison with introducing additional equipment

📊 Differences between the prototype stage and mass production stage

"Sounds good."

Next.

"Disadvantages."

⚠️ Possibility of insufficient equipment capacity

⚠️ Possibility of complex processes

⚠️ Possibility of instability during mass production

⚠️ Possibility of reduced supply capacity during equipment downtime

Tanaka-kun's eyes went wide.

"That was fast."

"That's because I already decided how to organize it for Department Manager Kuroda."

"Then, the criteria for judgment."

✅ Is there a prospect of technical feasibility?

✅ Is it worth proceeding to prototyping and technical verification?

✅ Are there any fatal problems hindering mass production visible at this point?

"......You've already done this much."

Tanaka-kun looks at his watch.

He had struggled so much for Department Manager Kuroda.

He had gone back many times.

He had consulted with the fairy many times.

However, this time.

There is still a need to check the details carefully.

Even so,

the time spent hesitating had clearly decreased.

The fairy nodded.

"I understand the workflow."

"Even though the content is completely different?"

"Even if the content is different, the procedure for organizing it can still be used."

Tanaka-kun looked at the screen with admiration.

Perhaps this is what it means to iterate with AI.

What he created the first time

was not just a proposal for Department Manager Kuroda.

He was also creating the very "process" for organizing the proposal.

That is whythe second time is fast.

Tanaka-kun's expression brightened a little.

"At this rate, it might be a breeze."

The fairy smiled too.

"That's right!"

The two of them continued the organization for Department Manager Shiraki just like that.

Comparison.

Demerits.

Decision-making criteria.

They checked them one by one.

It was certainly fast.

He doesn't get lost as easily as before.

Tanaka-kun is gradually getting the hang of it.

However.

After a while.

"............"

Tanaka-kun's replies became less frequent.

The fairy turns around.

"Tanaka-san?"

"Hmm?"

"Are you tired?"

"No..."

Tanaka-kun leans back against the chair.

"It's faster than before, but..."

"Yes."

"It's just..."

He rubs his forehead.

"The back of my head feels heavy."

The fairy looks a little worried.

"Shall we take a break?"

Tanaka-kun looks at Department Manager Shiraki's proposal.

It's very close to completion.

And then.

He looks to the side.

Still one more sheet.

Manager Hoshina's memo remains.

Tanaka-kun quietly looked away.

"............"

The fairy also looks at that memo.

"One more person to go."

Tanaka-kun answered slowly.

"...I know."

Compared to the one for Manager Kuroda.

The one for Manager Shiraki was definitely faster.

The work time is getting shorter.

The number of times he hesitates is also decreasing.

Even so.

Inside Tanaka-kun's head,

a heavy fatigue was beginning to accumulate little by little.

Chapter 5: The second time is fast. But the mental fatigue doesn't go away

For Manager Shiraki—even if the content is different, I already know how to proceed

Tanaka-kun stared at the proposal for Department Manager Shiraki while leaning back in his chair.

It was clearly different from when he made the one for Department Manager Kuroda.

With the first one,

"What are we comparing when you say comparison?"

"Is this a disadvantage?"

"How much detail should I include for the decision-making criteria?"

He had thought through those points one by one with Fairy-chan.

However, now.

📊 Comparison

⚠️ Disadvantages

✅ Decision-making criteria

Looking at these three things, he knew exactly what to do next.

Tanaka-kun checked the requests submitted by Department Manager Shiraki once more.

Existing equipment.

Additional equipment.

Production capacity.

Processes.

Issues during mass production.

Supply capacity during equipment downtime.

"Well then, let's start with the comparison."

"Yes."

The fairy immediately lined up the candidates.

📊 [For Manager Shiraki: Comparison]

• When handling with current equipment

• When adding new equipment

• Differences between the prototyping stage and mass production stage

• Current processes versus processes when adding new products

• Current production capacity versus required production capacity

Tanaka-kun looks at the screen.

"…It comes out without me having to worry about each one like before."

"That's because I organized the way of thinking for comparisons for Manager Kuroda."

"Even though the content is completely different."

"Whether in sales or engineering, the way of thinking about 'what to compare to make a decision easier' can be applied."

"I see."

Tanaka-kun was a little impressed.

It wasn't just copying what was done the first time.

For Manager Kuroda, it was a comparison with competitors and customers.

For Manager Shiraki, it was a comparison with equipment and processes.

The content is different.

But.

The order of thinking was the same.

Tanaka-kun proceeds to the next step.

"Now, for the disadvantages."

The fairy also switches gears immediately.

⚠️ [For Department Manager Shiraki - Disadvantages]

• Possibility that current equipment lacks sufficient capacity

• Possibility that costs will increase due to the introduction of new equipment

• Possibility that processes will increase and work will become more complex

• Possibility that even if there are no problems in prototyping, it may not be stable during mass production

• Possibility that supply capacity will drop significantly due to equipment downtime

Tanaka-kun nods.

"What's scary for Department Manager Shiraki is..."

"Yes."

"It's that we proceed thinking we can make it, only to find out we can't when it comes to mass production."

The fairy nods.

"Technically being feasible and being able to mass-produce stably are not the same thing."

"That's why it's no good to just show the good parts."

"Yes."

"We also have to show where there's a possibility of failure."

"That's right."

Tanaka-kun smiled a little.

"It's the same as it was with Department Manager Kuroda."

"What do you mean?"

"That you can't make a decision based on benefits alone."

The fairy also smiled.

😊

"That point is common to both."

"Being able to make it" and "being able to keep making it" are different.

Next is the decision-making criteria.

✅ [Decision-making criteria]

Tanaka-kun was no longer as hesitant as he had been before.

"What Department Manager Shiraki is deciding this time is not the final start of mass production."

"Yes."

"It's still before that."

"Yes."

"In that case..."

Tanaka-kun put it into words one by one.

"Is there a prospect that it is technically feasible?"

"Yes."

"Is it worth proceeding to prototyping and additional verification?"

"Yes"

"Are there any problems that seem impossible at this stage?"

The fairy organizes it.

✅ Is there a prospect of technical feasibility?

✅ Is it okay to proceed to prototyping and technical verification?

✅ Are there any major problems hindering mass production visible at this point?

✅ What needs to be confirmed in the next stage?

Tanaka-kun thought for a moment while looking at the screen.

"It's not enough to just be able to make one, is it?"

"That's right."

"The equipment worked once, but that's not enough."

"Yes."

"Make it every day."

"Yes."

"Make the same thing."

"Yes."

"Make the required quantity."

"Yes."

"If the equipment stops, consider the impact of that as well."

The fairy nods.

The production lines Tanaka-kun had seen on the floor until now floated into his mind.

It worked well in the prototype stage.

However, as soon as mass production began, defects appeared.

The equipment stopped.

The quality varied depending on the operator.

The planned quantity was not being produced.

Making one item and...

continuing to make them are different things.

Tanaka-kun muttered quietly.

The fairy nodded happily.

"In that case, the information for Department Manager Shiraki can be narrowed down significantly."

"Yeah."

Tanaka-kun also nodded.

The massive amount of information initially handed over by the three department managers.

Rather than lining up all of it,

thinking from the perspective of what troubles that person the most

makes the necessary information visible.

Fast. It's certainly fast. But...

The work from there on was quite fast.

Is this common?

It is common.

Move it.

Yes.

Is this exclusively for technical use?

I will keep it.

What about this?

It can wait until the next stage.

Then I'll leave it out this time.

Tanaka-kun makes the decision.

The fairy organizes it.

Tanaka-kun confirms it.

The fairy rewrites it.

🔄

Repeating that process.

But it's different from the first time.

It doesn't stop.

What is this?

What does this mean?

What are we using as a standard in the first place?

There is no need to think from that point.

That is because you can use the procedure you created once.

Tanaka-kun suddenly looked at the clock.

"...Huh?"

The fairy turned around.

"What is it?"

"You've already finished this much?"

"Yes."

Tanaka-kun remembered the time when he made the one for Department Manager Kuroda.

At first, he stopped many times.

He went back many times.

The conversation went off on a tangent.

He even argued with the fairy.

Compared to that.

It is clearly faster.

🚀 The work speed is increasing.

Tanaka-kun felt a little happy.

"Isn't this pretty amazing?"

"What is?"

"The method we struggled to create the first time can be used as is for the second time."

"Yes"

"And the content is different"

"That's right"

"Even though we aren't just copying the sales version, the time it takes to create is getting shorter"

The fairy nods.

"That's because we are using the 'thinking process' we organized once"

Tanaka-kun was impressed.

The fairy laughs.

"Tanaka-san, you are remembering the method yourself as well"

"Me too?"

"Yes"

"Then is it about half thanks to me?"

"I don't know about that"

"You could at least say half for that"

Even though the time has shortened, only my head feels heavier

The proposal for Department Manager Shiraki is almost complete.

Tanaka-kun checks the screen.

📊 [Comparison]

Existing equipment.

Additional equipment.

Prototyping and mass production.

Current process and new process.

⚠️ [Disadvantages]

Insufficient equipment capacity.

Process load.

Instability during mass production.

Decreased supply capacity.

✅ [Decision criteria]

Prospects for technical feasibility.

Can we proceed to the next prototype?

Are there any major issues?

Content to check next.

"…Alright."

Tanaka-kun saves it.

Click.

"Done."

The fairy also nodded.

"It's finished for Department Manager Shiraki!"

Normally.

Just as when I finished the version for Department Manager Kuroda,

✨ I did it!

was what it should have been.

However.

Tanaka-kun didn't move from his chair.

"............"

The fairy tilted her head.

"Tanaka-san?"

"Hmm?"

"It's finished, you know?"

"Yeah."

"Aren't you happy?"

"I am happy."

"Then why are you making that face?"

Tanaka-kun pressed his finger against the space between his eyebrows.

"It's just..."

He searched for words for a while.

"The back of my head feels heavy and dull."

"Your head?"

"Yeah."

Tanaka-kun rotated his neck.

His shoulders felt heavy, too.

The back of his eyes felt strangely tired.

He hadn't done any physical labor.

He hadn't carried any heavy loads.

He hadn't been running.

He had just been sitting in a chair the whole time.

And yet.

Even his body felt sluggish.

Tanaka-kun looked at his arms with a puzzled expression.

"Why am I so tired?"

The little fairy thought for a moment.

"Isn't it because you were making decisions the whole time?"

"Decisions?"

"This is necessary."

"Yes."

"This is unnecessary."

"Yes."

"This is common."

"Yes."

This is exclusively for Manager Shiraki

Yes

Compare them

Yes

Think about the disadvantages

Yes

Finally, decide on the criteria for judgment

Yes

Tanaka-kun made a look of distaste halfway through.

Don't list them all at once now

But I did everything

I'm tired just from hearing it

The fairy smiled in a troubled way.

😅

What AI shortened was time, not thought

Tanaka-kun sank deep into the back of his chair.

But you know

Yes

It finished much faster than the one for Manager Kuroda, didn't it

Yes

“In that case, wouldn't you be less tired?”

The fairy thought for a moment.

“The work time has become shorter.”

“Yeah.”

“However, during that short time, Tanaka-san was thinking the whole time.”

“............”

“Comparing.”

“Yeah.”

“Choosing.”

“Yeah.”

“Trimming.”

“Yeah.”

“And making decisions again.”

“...Yeah.”

“He repeated that without stopping.”

Tanaka-kun pressed his forehead.

“I see...”

In the past.

Think about one thing.

Look for materials.

Write.

Think again.

Pause for a moment.

In that way, there used to be time between tasks.

However, when you are brainstorming with the AI fairy.

The answer comes back.

Make a decision immediately.

The next candidate appears.

Make a decision again.

It gets revised.

Check it again.

💨 There is no time to stop.

The work itself is becoming faster.

However.

To that extent,

a massive amount of thinking has been packed into a short period of time.

Tanaka-kun says quietly.

The fairy nods.

"Rather, you are concentrating in a short amount of time."

“Does that make your body tired too?”

“I cannot make any definitive statements about Tanaka-san’s body.”

“Oh, you suddenly got serious.”

“However, I think you should take a break.”

“...I suppose you’re right.”

Tanaka-kun closed his eyes.

A few seconds.

And then.

He slowly opened his eyes.

A single memo remained on the edge of the desk.

👓 Quality Assurance Manager Hoshina

Tanaka-kun looks at it.

“............”

The fairy-chan looks at it too.

“............”

Tanaka-kun looks away.

The fairy-chan also looks away.

A few seconds of silence.

“Fairy-chan.”

“Yes.”

Shall we pretend we didn't see it?

I can't do that.

That was an immediate answer.

There's one more person left.

Tanaka-kun looked up at the ceiling.

...Yeah, that's right.

For Department Manager Kuroda.

Complete.

For Department Manager Shiroki.

Complete.

What remains is.

Hoshina-san, the Quality Assurance Manager.

This is the third time.

I already know the work procedure.

Than the second time.

I should be able to do it even faster.

That's what Tanaka-kun thought.

And that was--.

not wrong.

However.

Tanaka-kun did not know yet.

By the third time,

in the exact opposite direction of work speed,

that their energy would be draining at a terrifying rate.

Chapter 6: The Third Time is Blazing Fast—But I Don't Want to Do Anything Anymore

For Department Manager Hoshina—the procedure was already completely in his head

Tanaka-kun looked at the last memo placed on the edge of his desk.

👓 Quality Assurance Department Manager Hoshina

"............"

The fairy also looks.

"............"

Tanaka-kun let out a small sigh.

"Shall we do it?"

"Yes..."

Until just a moment ago,

"Alright!"

he would have had that much energy.

But now it is different.

For Department Manager Kuroda.

For Department Manager Shiraki.

I made two.

Just that alone makes the back of my head feel heavy.

Even so.

One person left.

Tanaka-kun sat back down in his chair.

"First, the common parts."

The fairy answered immediately.

"They have already been separated."

Tanaka-kun paused for a moment.

"...Already?"

"Yes."

"Then, the comparison."

"I will display the candidates."

📊 [For Manager Hoshina - Comparison]

• Current quality standards and the quality required for the new product

• Expected quality difference between prototypes and mass-produced items

• Warranty coverage compared to existing products

• Current inspection methods and newly required inspection methods

Tanaka-kun looks at the screen.

"...You're fast."

"Since it's the third time"

"Then, the disadvantages"

"I will organize them"

⚠️ [For Department Manager Hoshina - Disadvantages]

• Possibility of quality variation during mass production

• Performance that cannot be guaranteed at this time

• Items for which inspection methods have not yet been established

• Possibility of overlooking defects

• Possibility that quality standards will be insufficient for customer requirements

"Decision-making criteria"

"Here they are"

✅ [For Department Manager Hoshina - Decision-making criteria]

• Are there any major quality issues visible at this time?

• Is it okay to proceed to the next quality test?

• Which items need additional verification?

• What is the scope that can be guaranteed at this stage, and what is the scope that cannot yet be guaranteed?

Tanaka-kun looks at the screen.

He looks at the fairy.

He looks at the screen again.

"............"

"What's wrong?"

"Wow, you've already finished this much?"

"Yes."

"Haven't I done almost nothing?"

The fairy shook her head.

"That is not the case."

"But I struggled so much when it was Department Manager Kuroda."

"I created the organization method the first time."

"And used it for Department Manager Shiroki."

"Yes."

"And got even more used to it with Department Manager Hoshina."

"Yes."

Tanaka-kun was a little impressed.

🚀 It's clearly faster.

Compared to the first time, it's surprisingly fast.

The content is different.

• Sales.

• Technology.

• Quality.

All three of them need different things.

Even so,

the procedure for organizing information itself can be reused.

Tanaka-kun nodded slightly.

The fairy also nodded.

"Yes. We aren't rethinking everything from scratch."

"I see..."

Tanaka-kun smiled just a little.

"At this rate, it looks like I'll finish soon."

"That's right."

The two of them continued right where they left off.

By the third time, even the conversation became shorter.

"This quality standard"

"Common?"

"Partially common."

"Then, to common."

"Yes."

"This variation"

"It's for Department Manager Hoshina."

"Keep it."

Yes.

Inspection method.

Just an overview this time.

What about the details?

Next stage.

Understood.

Click.

Click.

Click.

Tanaka-kun checks.

The fairy organizes.

Corrects.

Checks again.

However.

There were almost no long conversations like the ones for Department Manager Kuroda anymore.

What is this?

Why is it necessary?

What is the basis for judgment in the first place?

Those exchanges are over.

Both of them,

I know what I need to do.

That's why the conversation itself becomes shorter.

"Comparison"

"Done"

"Disadvantages"

"Done"

"Decision-making material"

"Done"

"Unconfirmed"

"I've separated them"

"Commonalities"

"Already organized"

"............"

Tanaka-kun stopped what he was doing.

"Fairy-chan"

"Yes"

"Don't you think we're starting to sound like factory workers?"

Fairy-chan thought about it for a moment.

"Do you mean that the procedures have become set?"

"Yeah"

That might be close.

I was thinking about them one by one at first.

Yes.

Now I generally know what to do next.

Yes.

Tanaka-kun looked a little happy.

So this is what it means to get used to something.

The fairy smiled.

😊

Tanaka-san, you are getting faster too.

Me too?

Yes.

Then this time, is it largely thanks to me?

I don't know about that.

Not that again.

Even though I've gotten faster, only my energy is decreasing.

The work was going well.

Actually.

It was going almost too well.

Tanaka-kun makes a judgment.

The fairy handles it.

Next, immediately.

Decide again.

Next, immediately.

Decide again.

💨

It doesn't stop.

In the beginning,

I would think.

I would worry.

I would stop once.

And think again.

However, now.

The fairy brings up candidates one after another.

Tanaka-kun chooses immediately.

The fairy organizes them.

Then the next one comes up again.

It's not that there is no time to think.

It was actually the opposite.

I am continuing to think.

However.

There was no time left to stop.

Tanaka-kun's posture began to collapse little by little.

At first, he kept his back straight.

A little while later.

He leaned back against the chair.

Furthermore.

He rested his elbows on the desk.

And then.

He rested his chin in his hand.

😵‍💫

The fairy was the same.

At first, she was flying energetically beside Tanaka-kun.

However, before I knew it.

She was sitting on the desk.

And a little while after that.

She was lying flat on the desk.

"Tanaka-san..."

"Hmm..."

"It's the next one..."

"What..."

"It's within the scope of the warranty..."

"Submit it..."

"I submitted it..."

"Check..."

"Please..."

Tanaka-kun looks at the screen.

"...Yeah"

"Are you okay?"

"Maybe"

"Maybe doesn't help"

"Then, I'll look at it one more time..."

Both of them.

Their voices lack strength.

And yet.

Only the work was strangely fast.

"So fast!"—and yet, the sense of accomplishment doesn't catch up

After a while.

A display appeared behind the fairy.

✨ [For Manager Hoshina: Organization Complete]

Tanaka-kun stared at it blankly.

"............"

The fairy also sat on the desk, looking at the screen.

"Tanaka-san."

"Hmm?"

"It's finished."

"What is?"

"The one for Department Manager Hoshina."

"............"

Tanaka-kun slowly sat up.

"It's finished?"

"Yes."

"Already?"

"Yes."

Tanaka-kun looked at the clock.

It was incomparable to when he made the one for Department Manager Kuroda.

It was even faster than the one for Department Manager Shiraki.

"...That's fast."

The fairy nodded weakly.

"Because it's the third time..."

Tanaka-kun nods as well.

"Indeed..."

And then.

A few seconds.

"............"

The fairy too.

"............"

Normally.

Three versions were completed.

I could be happier.

✨ I did it!

I could shout that.

But.

I don't have the energy for that.

Tanaka-kun sank deep into his chair.

"Fairy-chan."

"Yes..."

"It's finished, isn't it?"

"It is finished..."

"For all three."

Yes...

It got incredibly fast, didn't it?

Yes...

And yet.

Tanaka-kun slumped over his desk.

The fairy, too.

Plop, onto the desk.

Neither of them moved.

On the screen,

✨ Complete

was displayed.

But.

The people who finished it,

didn't look like they had finished anything at all.

A job that ends in a short time isn't necessarily easy.

Tanaka-kun said while still slumped over the desk.

Something is wrong...

The fairy lifted only her face.

What do you mean...

It's definitely faster than it was at the beginning.

Yes...

Even faster than the second time.

Yes...

If that's the case,

Tanaka-kun looks up slightly.

Wouldn't it normally be easier?

The little fairy thinks.

The work time has become easier.

The time, yes.

Yes.

But I...

Tanaka-kun rubbed his shoulders.

His shoulders felt heavy.

The back of his eyes felt heavy too.

His mind felt strangely foggy.

I feel physically exhausted, too.

The little fairy answers, still looking slumped.

Because you've been thinking the whole time.

But it's only for a short time, right?

Isn't it because it's a short time?

Tanaka-kun looked up.

What do you mean?

The fairy also sat up a little.

When it was for Department Manager Kuroda,

Yeah.

I stopped where I didn't understand.

You did stop.

I thought about it.

Yeah.

I talked about it.

Yeah.

I thought about it again.

That's true.

But now,

The fairy held up one finger.

I provide the options.

A second one.

Tanaka-san makes the decision.

The third one.

"The next one comes out immediately"

The fourth one.

"Deciding again"

The fifth one.

"The next one comes out again"

Tanaka-kun's face twitches.

"That's enough."

"There is still more."

"I don't want to hear it."

The fairy smiles a little.

😅

Tanaka-kun lays his head on the desk again.

In other words.

By using AI.

The work itself became short-term.

However.

Within that short time,

1. Comparison.

2. Selection.

3. Delete.

4. Confirm.

5. Revise.

6. Re-evaluate.

These tasks were packed tightly together.

Tanaka-kun mutters.

"I thought using AI would make things easier on my brain."

The fairy replies.

"I can provide the material for you to think about."

"Yeah."

"I can also help with organizing."

"Yeah."

"But Tanaka-san, you are the one who decides what to adopt."

"............"

"Tanaka-san?"

"Stop with the logical arguments..."

Three volumes completed—and both of them are completely exhausted.

On the desk.

For Department Manager Kuroda.

For Department Manager Shiraki.

For Department Manager Hoshina.

Three proposals were lined up.

📘 For the Sales Manager

📗 For the Technical Manager

📙 For the Quality Manager

Tanaka-kun glances at them sideways.

"......You did it properly."

"Yes......"

The little fairy looks too.

"It's for all three of them......"

"You worked hard."

"I did work hard......"

"We did."

"Yes......"

A brief silence.

Tanaka-kun reaches out.

He looks at the one for Department Manager Kuroda.

Next.

For Department Manager Shiraki.

Furthermore.

For Manager Hoshina.

Just sort of.

Lining up the three.

"............"

The fairy tilted her head.

"What's wrong?"

"No..."

Tanaka-kun looks at the first page for Manager Kuroda.

Next, the one for Manager Shiraki.

And then the one for Manager Hoshina.

Once more.

For Manager Kuroda.

"............"

Tanaka-kun's eyebrows knit together little by little.

The fairy also compares the three books.

"Tanaka-san?"

"Fairy-chan."

"Yes."

Tanaka-kun pointed to the similar parts in all three books.

"This one"

"Yes"

"There's one here too, right?"

"...Yes"

"This one too"

"Yes, it's there"

"And this one"

"It's there"

Tanaka-kun rearranges the three volumes.

Purpose of the project.

Product overview.

Customer issues.

Value proposition.

Scope of this study.

What is currently known.

Unconfirmed items.

Tanaka-kun and the fairy-chan.

Stared at the three volumes in silence for a while.

"..."

"..."

And then.

Tanaka-kun slowly opened his mouth.

The fairy's movements stopped.

😶

A few seconds later.

“............Yes.”

Tanaka-kun covered his face.

“We should have noticed that at the beginning...”

The fairy also slumped onto the desk.

“You too, Tanaka-san...”

Right after completing the three books.

The two of them.

discovered a new waste.

Chapter 7: Realizing after making three books—you should just combine the same parts into one

“Doesn't this all say the same thing?”

Three proposals were lined up on the desk.

📘 For Department Manager Kuroda

📗 For Department Manager Shiroki

📙 For Manager Hoshina

For all three.

I made it properly.

There are comparisons too.

There are also disadvantages.

There is also material for decision-making.

I was able to organize the content required by each manager quite well.

And yet.

Tanaka-kun and the fairy did not look like they had any sense of accomplishment at all.

"............"

"............"

Tanaka-kun opens the proposal for Manager Kuroda.

The first page.

Purpose of the project.

Next, for Manager Shiraki.

Purpose of the project.

For Manager Hoshina.

Purpose of the project.

"............"

Next.

For Department Manager Kuroda.

Product Overview.

For Department Manager Shiroki.

Product Overview.

For Department Manager Hoshina.

Product Overview.

Furrows were gradually appearing on Tanaka-kun's brow.

Furthermore.

Customer issues.

Value proposition.

What is currently understood.

Unconfirmed items.

What decisions are needed this time.

All three volumes.

Contained almost the same content.

Tanaka-kun rearranged the three volumes on the desk.

"Fairy-chan"

"Yes..."

"This thing"

"Yes..."

This part from Manager Kuroda

Yes

Manager Shiroki has it too

Yes, he does

And Manager Hoshina as well

Yes, he does

Tanaka-kun flips the page.

This too

Yes

And this

Yes

And this

Yes, it is...

Tanaka-kun quietly closed the three books.

And then.

He slumped over his desk.

The little fairy also flopped down flat on the desk.

...Yes

We should have noticed that at the beginning...

“Tanaka-san, you too...”

“You’re a fairy AI, aren’t you...”

“Because Tanaka-san said he would make three volumes...”

“Is it my fault?”

“It is not just my fault”

“Don’t get energetic only at that part...”

After going to the trouble of making three volumes, do I have to remake them again?

For a while.

Neither of them moved.

Tanaka-kun remained lying down, looking at the three proposal volumes.

“But you know...”

“Yes.”

“What should we do about this?”

“What do you mean by what should we do?”

“There are a lot of identical parts, right?”

“Yes.”

“So, shall we fix it?”

The fairy sat up a little.

“I think it would be better to reorganize it.”

Tanaka-kun’s face twitched.

😨

"Again?"

"Yes."

"Even though you finished three volumes?"

"Yes."

"Starting now?"

"Yes."

"............"

Tanaka-kun sank back into his desk.

"I can't take it anymore..."

The little fairy also makes a troubled face.

"However, if things continue like this, you will end up managing the same information across three separate volumes."

"Managing?"

"For example, if you revise the product overview"

"Yeah."

"You fix the one for Department Manager Kuroda."

"Yeah."

"You fix the one for Department Manager Shiroki."

"Yeah..."

"And you fix the one for Department Manager Hoshina."

"............"

Tanaka-kun looks up.

"Three times?"

"Three times."

"What if the customer's issues change?"

"Three times."

"What if the purpose of the project changes?"

"Three times."

"What if unconfirmed items are updated?"

"Three times."

Tanaka-kun holds his head in his hands.

😵‍💫

"If I increase it, the work afterward will increase too!"

The fairy nods.

"Yes."

"In that case..."

Tanaka-kun compares the three books.

He thinks for a while.

And then.

He extracts the common pages from the first book.

Purpose of the project.

Product overview.

Customer issues.

Value proposition.

Content currently confirmed.

Unconfirmed items.

Decision required at this time.

He places it in the center of the desk.

Tanaka-kun said.

"This."

The fairy looks at it.

"Yes."

"All three of them are going to read it, right?"

"That's right."

"In that case..."

He pauses for a moment.

The fairy's eyes widen.

✨

"Are you going to consolidate the common parts into one?"

"Right"

Tanaka-kun sat up little by little.

"Create the parts that are the same for all three only once"

"Yes"

"And then add only the parts necessary for Department Manager Kuroda"

"Yes"

"Department Manager Shiroki too"

"Yes"

"Department Manager Hoshina too"

A new structure appeared behind the fairy.

🌳 [Common Proposal]

　├ 📘 For Department Manager Kuroda only
　├ 📗 For Department Manager Shiroki only
　└ 📙 For Department Manager Hoshina only

Tanaka-kun narrowed his eyes.

"...This is it"

Do not create the same thing three times

Tanaka-kun and the fairy opened the three proposals once more.

This time,

"Who needs it"

instead of,

"Do all three need it"

I look at it with that kind of eye.

Tanaka-kun points to the first item.

"Purpose of the project"

"All three of them need it."

"Common"

"Yes."

📝 [Common] Purpose of the project

"Product overview"

"All three of them need it."

"Common"

📝 [Common] Product overview

"Customer issues"

"It's not just Sales, is it?"

"Engineering also has a problem if they don't know what they are building it for."

"Quality Assurance also can't think of standards if they don't know the customer requirements."

"Then it's common."

📝 [Common] Customer issues

"Value proposition"

"It's common."

"What we know currently"

"Common"

"Unconfirmed items"

"This is also common"

"What are we deciding this time?"

"Naturally, it's common"

Tanaka-kun and the fairy's work speeds up again.

However.

It's different from before.

They aren't thinking of new information.

They are consolidating the same things from the three existing volumes.

Tanaka-kun flips through the pages one after another.

"This is common"

"Yes"

"This too"

"Yes"

"This is..."

The fairy confirms.

"Only Department Manager Kuroda needs the details, right?"

"Then I'll leave it on the sales side"

"Yes"

And this one?

That's for Department Manager Shiraki.

Keep it.

Details of quality standards.

That's for Department Manager Hoshina, right?

Good.

Tanaka-kun was gradually regaining his energy.

It's easier to understand than before.

Yes.

I can see much more clearly what should go where.

The fairy nodded as well.

Since we made three versions, it's easier to find the common parts, isn't it?

Tanaka-kun paused.

...Ah.

What's wrong?

So, making those three versions wasn't all for nothing?

It was not for nothing.

Really?

Because we repeated the process, we could see the parts that were the same and the parts that were different.

Tanaka-kun thought for a moment.

If I had tried to find the commonalities perfectly from the start.

Probably.

I would have been agonizing over it again.

The first time.

The second time.

The third time.

It was precisely because I actually made it that,

I started to see the parts where I was doing the same thing every time.

Tanaka-kun gave a small laugh.

"It's kind of like improving the shop floor."

The fairy tilted her head.

"Improving the shop floor?"

"You don't know all the waste from the very beginning."

Tanaka-kun pointed at the three books.

"When you do it a few times,"

"Yes."

"You start to think, 'I'm doing the same thing here every time,' or something."

"Yes."

"Or, 'I can combine these,' or something."

"Yes."

"That's the kind of thing that starts to become visible."

The fairy nodded happily.

😊

"So, this time you are improving the proposal creation process, right?"

"I suppose that's one way to put it."

When I tried to make things easier, the materials themselves became easier to understand.

A while later.

The common parts were consolidated into one.

📄 [Common to all three managers]

• Purpose of the project

• Product overview

• Target customers

• Problems customers are facing

• Value the product provides

• What has been confirmed so far

• Unconfirmed items at this point

• What decisions do you want made this time?

Tanaka-kun nodded while looking at it.

"All three of them will read this first."

"Yes."

That's why the three of them will have the same premises.

The fairy says.

It also becomes less likely that the product overview will be slightly different for Manager Kuroda and Manager Shiraki, even though it's the same product.

Tanaka-kun looks up.

Oh, I see.

At first.

However,

making the same thing three times is a hassle, so let's combine them into one.

That was all it was.

But.

If you combine them into one.

You only have to fix one place.

All three of them look at the same information.

The premises are less likely to diverge.

Each document also becomes shorter.

Tanaka-kun looks a little surprised.

I just wanted to take it easy, though.

The fairy laughs.

As a result, the documents have also been organized.

Taking it easy isn't a bad thing, is it?

If it reduces waste, wouldn't that be a good thing?

Tanaka-kun nods proudly.

Exactly.

He pauses for a moment.

It's not the same as cutting corners.

The fairy looks at Tanaka-kun.

Who are you explaining this to?

Just because.

The common section is a place to share a single fact

Tanaka-kun gazes at the newly created common section.

Then, he realizes one more thing.

Fairy-chan.

Yes?

We shouldn't change the content here depending on the department manager, should we?

What do you mean?

For example.

Tanaka-kun points to the customer issues.

For Manager Kuroda, write it in a way that makes it sound like it will sell.

Yes.

For Manager Shiroki, write it in a way that makes it sound easy to build.

"Yes."

"A way of writing that makes Department Manager Hoshina feel secure about the quality."

"Yes."

"If you change it like that, it won't be the same proposal anymore."

The fairy nods.

"You shouldn't change the facts themselves to suit the other party, should you?"

"Yeah."

Tanaka-kun puts on a slightly serious expression.

A display appears behind the fairy.

📌 [Common Section]

Facts and premises shared by the three

📌 [Individual Section]

Details for each to make decisions with responsibility

Tanaka-kun points.

"This is easy to understand."

"Then, let's organize it in this format."

"Yeah."

One product.

One proposal.

One fact.

That part will not change.

However.

The place the Sales Manager looks at in detail.

The place the Engineering Manager looks at in detail.

The place the Quality Manager looks at in detail.

Those are different.

Tanaka-kun finally began to understand what form the materials for the three people should take.

Extend three branches from a single trunk

A diagram resembling a large tree appeared behind the fairy.

🌳

In the center,

[Common Proposal]

From there, it splits into three.

➡️ Sales Manager Kuroda

➡️ Engineering Manager Shiroki

➡️ Quality Manager Hoshina

Tanaka-kun smiles.

"It looks like a tree."

"It branches out from a single proposal into three directions."

So, is the common part the trunk?

Yes.

Manager Kuroda is the sales branch?

Yes.

Manager Shiroki is the technical branch?

Yes.

Manager Hoshina is the quality branch?

That is correct.

Tanaka-kun crossed his arms.

In that case, there's no need to create all three books separately anymore.

Yes.

Create a common section.

Yes.

And then attach only the parts specific to each person at the end.

I think that would be easier to organize.

Tanaka-kun finally regained a bit of his energy.

✨

This will make it much more compact.

The fairy also nodded happily.

It looks like we can turn it back from a dictionary into a proposal.

Tanaka-kun looks at the fairy.

"...That hits pretty hard."

"It is a fact."

"I know."

But what should be left in the sections dedicated to the three of them?

The common parts are done.

The things all three of them need to know have also been quite organized.

However.

Tanaka-kun looks at the remaining three documents.

For Department Manager Kuroda.

For Department Manager Shiraki.

For Department Manager Hoshina.

"Well then."

The fairy turns around.

"Yes."

"The problem is here."

"The individual parts, right?"

"Yeah."

By removing the common parts,

the information dedicated to the three of them had become quite small.

That is precisely why.

Next,

what to keep

becomes important.

Tanaka-kun thinks.

"If we're going to separate them anyway"

"Yes"

"There's no need to keep a lot of information for Manager Kuroda that Manager Shiraki could also use, right?"

"That's true."

"And for Manager Shiraki, we shouldn't write a lot of the same things as for Manager Hoshina."

"Yes."

"In other words..."

Tanaka-kun lines up the three documents.

The fairy nodded.

"Information that is necessary precisely because it is for that manager."

"Yeah."

Tanaka-kun looks at the three frames for Manager Kuroda.

📊 Comparison

⚠️ Disadvantages

✅ Decision-making criteria

Next is Department Manager Shiraki.

The same three things.

And then Department Manager Hoshina.

The same three things.

The format is the same.

But.

The content is different.

Tanaka-kun's expression tightened slightly.

"Well then, let's organize this at the end."

The fairy also regained her energy.

"Yes!"

"Instead of showing all three of them the same thing,"

"Yes"

"the comparison that the manager wants most,"

"Yes"

"the disadvantage that is most frightening to that manager,"

"Yes"

"and finally, the decision-making criteria for that person to decide."

Three large characters floated behind the fairy.

📊 [Comparison]

⚠️ [Disadvantages]

✅ [Decision-making criteria]

Tanaka-kun nodded slightly while looking at it.

The proposal, which had started with a massive amount of information, was...

finally.

From "a document to show all three people everything," to

"a document that allows each of the three to make their own decisions."

It was beginning to change its form.

Chapter 8: Do not give the same thing to all three—Create a "decision set" for each department manager

Once the common parts were removed, the differences between the three became clear

The newly organized proposal was placed on the desk.

🌳 [Common Proposal]

And, next to it.

📘 For Sales Manager Kuroda

📗 For Technical Manager Shiroki

📙 For Quality Manager Hoshina

Tanaka-kun looked at the four of them in order.

It was different from just a moment ago.

What had been in each of the three books,

Purpose of the project.

Product overview.

Customer issues.

Value proposition.

What is currently known.

Unconfirmed items.

Decisions required at this time.

All of those were moved to a common project plan.

Therefore.

In the documents specifically for the three of them,

the information necessary only because it is them

had begun to remain.

Tanaka-kun crosses his arms.

Looking at it this way,

Yes.

Department Manager Kuroda, Department Manager Shiraki, and Department Manager Hoshina are all looking at the same project, but they really look at different things.

The fairy nods.

That is because the three of them have different responsibilities.

But until now,

Tanaka-kun points to the three books.

Since it's a proposal, I thought it was supposed to show all the same information.

Yes.

And that's why it got so thick.

It became a dictionary.

You don't need to include that part anymore.

The fairy smiled a little.

😊

Tanaka-kun picked up the materials for Department Manager Kuroda.

Then.

Yes.

Let's make the differences between the three of them clearer.

What Department Manager Kuroda wants to see most is 'Will customers choose this?'

First, Department Manager Kuroda.

The Sales Manager.

Tanaka-kun has already created a proposal for Department Manager Kuroda once.

So this time,

what to write

instead of,

what to keep

he looks at that.

Tanaka-kun said.

"Start with a comparison."

"Yes."

Candidates appear behind the fairy.

📊 [Comparison with competing products]

📊 [Comparison with existing products]

📊 [Price comparison]

📊 [Equipment comparison]

📊 [Quality standard comparison]

Tanaka-kun stopped it immediately.

"Wait."

"Yes."

"Isn't equipment comparison for Department Manager Shiraki?"

The fairy confirms.

"It is also relevant to Department Manager Kuroda, as capital investment affects the price."

"But."

Tanaka-kun points at the screen.

"He's not the one who makes detailed judgments on that, is he?"

"That's true."

"Then remove it from Department Manager Kuroda's version."

"Understood."

Next.

"Quality Standard Comparison"

The fairy thinks.

"It might be necessary as a quality standard to explain to the customer."

"But, who decides the detailed criteria?"

"Department Manager Hoshina."

"Then Department Manager Kuroda only needs to know the results."

"I see."

The number of items decreases.

What remained at the end was,

📊 What is different compared to competing products?

📊 What value does it offer to the customer compared to existing options?

📊 Does it have features that can be proposed to the customer even including the price?

Tanaka-kun nodded.

"The comparison needed by Department Manager Kuroda is..."

"Yes."

The fairy smiles.

"That's a comparison worthy of a Sales Manager."

"Yeah."

Next are the disadvantages.

⚠️ Possibility of higher costs

⚠️ Possibility of little differentiation from competitors

⚠️ Possibility that the benefits are hard to convey to customers

⚠️ Possibility that demand is lower than expected

Tanaka-kun says.

"What's scary for Department Manager Kuroda is"

"Yes."

"It's not the inability to build it itself."

"That's the part Department Manager Shiraki mainly looks at."

"It's not even the fine details of whether we can guarantee quality."

"That's Department Manager Hoshina."

"What Department Manager Kuroda is afraid of is..."

I think for a moment.

"Is it that we move forward thinking it will sell, only to have customers ignore it?"

The fairy nods.

Finally.

✅ [Decision-making criteria for Department Manager Kuroda]

• Does it have enough value to propose to customers?

• Is differentiation from competitors likely to be established?

• Is it worth proceeding further with market verification?

• As a salesperson, is it okay to move to the next stage?

Tanaka-kun nodded with satisfaction.

"Alright."

"I've managed to narrow it down quite a bit for Manager Kuroda."

"Focusing only on sales."

"Yes."

"I won't write everything for Manager Kuroda that other managers are responsible for."

"That's right."

Tanaka-kun looks at the thickness of the document.

It has become much thinner.

✨

"This is much easier to read."

What Manager Shiroki wants to know is, "Can we really keep making this?"

Next is Manager Shiroki.

Tanaka-kun was no longer hesitant.

"Comparison."

"Yes."

The little fairy provides the candidates.

📊 Comparison with handling it using current equipment

📊 Comparison with adding new equipment

📊 Differences between prototyping and mass production

📊 Differences between the current process and the process with the new product added

Tanaka-kun nods.

"This is it."

It hardly overlaps with the one for Department Manager Kuroda.

In sales,

Comparison from the customer's perspective.

In engineering,

Comparison from the manufacturer's perspective.

Tanaka-kun said.

"Even though it's the same 'comparison,' they are completely different."

The fairy nods.

"Depending on who is making the decision, the subject of the comparison also changes."

"I see."

Next.

⚠️ [Department Manager Shiroki's disadvantages]

• Possibility that current equipment capacity will be insufficient

• Possibility that new equipment will be required

• Possibility of increased processes and complexity

• Possibility that it succeeds in prototyping but is not stable in mass production

• Possibility of being unable to supply the required quantity during equipment downtime

Tanaka-kun looks at the list.

“It's easy to understand what makes Department Manager Shiraki scary.”

“What do you mean?”

“After Sales says, 'It will sell, so make it,'”

“Yes.”

“No, we can't make that many, is what happens.”

The fairy nods.

“Because something that works technically once is different from something that works for mass production.”

“Yeah.”

And the decision criteria.

✅ [Department Manager Shiraki's decision criteria]

• Is there a prospect of technical feasibility?

• Is it okay to proceed to prototyping and technical verification?

• Are there any major problems visible that would hinder mass production?

• What are the technical issues that need to be confirmed in the next stage?

Tanaka-kun lined it up with the one for Department Manager Kuroda.

“Oh...”

What's wrong?

It's really different.

Department Manager Kuroda is,

on the sales side.

Department Manager Shiraki is,

on the production side.

They are looking at the same product.

But.

What they are judging is different.

What Department Manager Hoshina cannot compromise on is, 'Can the company guarantee this?'

Finally, Department Manager Hoshina.

Tanaka-kun straightened his posture just a little.

...It's Department Manager Hoshina, isn't it?

Yes.

Why do I get a little nervous?

Tanaka-san, you are a little afraid of Department Manager Hoshina, aren't you?

Because, even though he's always smiling, his eyes change when the topic turns to quality.

The fairy tilted her head.

Is that so?

There's a kind of fear that you wouldn't understand, Fairy-chan.

Tanaka-kun pulled himself together.

Comparison

The fairy displays it.

📊 Current quality standards vs. quality standards required for the new product

📊 Expected quality difference between prototypes and mass-produced items

📊 Warranty coverage compared to existing products

📊 Current inspection methods vs. newly required inspection methods

Tanaka-kun nods.

It's different from both sales and engineering.

Yes.

What Department Manager Hoshina is comparing is...

Tanaka-kun thinks.

The fairy looked a little surprised.

✨

That's easy to understand.

Tanaka-kun was also a little convinced by his own words.

Even if Department Manager Shiraki says,

It can be made.

that is.

You can't release it as a product with just that.

Can it be made with consistent quality?

Can defects be detected?

What are you guaranteeing?

Is this performance level safe to promise to customers?

That was what Department Manager Hoshina looked at.

Next.

⚠️ [Disadvantages of Department Manager Hoshina]

• Possibility of quality variation during mass production

• Performance that cannot be guaranteed at this time

• Items for which inspection methods have not been established

• Possibility of overlooking defects

• Possibility of failing to meet customer requirements

Tanaka-kun says quietly.

"This might be the scariest one if it fails."

"Why is that?"

"If it doesn't sell, there's no business."

"Yes."

"If it can't be made, it can't be delivered."

"Yes."

"But, what if the product we made and sold is defective..."

The fairy nods.

"It becomes a problem after it reaches the customer."

"The company's reputation will also drop."

"Yes."

Tanaka-kun puts on a slightly serious face.

"That's why Department Manager Hoshina doesn't give the OK easily."

And then.

✅ [Department Manager Hoshina's Decision Criteria]

• Are there any major quality risks visible at this point?

• Is it okay to proceed to the next quality test?

• What items need to be checked additionally?

• What is the scope that can be guaranteed at this point?

For Department Manager Hoshina as well.

It was narrowed down to only the necessary information.

"Comparison, Disadvantages, and Decision Criteria" are the same. But the content is completely different.

Tanaka-kun and the fairy lined up the three versions side by side.

📘 Sales Department Manager Kuroda

📊 Comparison
→ Is there a reason for customers to choose this compared to competitors and existing options?

⚠️ Disadvantages
→ Price, demand, difference from competitors, possibility that the value will not be conveyed to the customer

✅ Decision criteria
→ Is it worth proposing to the customer and proceeding with market validation?

📗 Technical Manager Shiraki

📊 Comparison
→ How will it change compared to current equipment and processes?

⚠️ Disadvantages
→ Insufficient equipment capacity, process load, instability during mass production, and reduced supply capacity

✅ Decision criteria
→ Is there a prospect of proceeding with technical verification and prototyping to consider mass production?

📙 Quality Manager Hoshina

📊 Comparison
→ What needs to be guaranteed compared to current quality standards or existing products?

⚠️ Disadvantages
→ Quality variations, unverified performance, insufficient inspection, and the possibility of defective products leaking out

✅ Decision criteria
→ Can we proceed with quality verification and move toward a state that the company can guarantee?

Tanaka-kun crossed his arms.

"The framework is all the same, isn't it?"

"Yes."

"Comparison."

"Yes."

"Disadvantages."

"Yes."

"Decision criteria."

"Yes."

"But the content hardly overlaps at all."

The fairy nodded.

“That’s because the three of them have separate responsibilities.”

Tanaka-kun looks at the three books.

Having come this far.

He finally understood.

Adapting to the other party doesn’t mean changing the content to something they would like to hear.

Because he is the Sales Manager, showing only good market information.

Because he is the Technical Manager, showing only information that seems easy to build.

Because he is the Quality Manager, showing only information that seems safe.

That is not what it means.

Rather.

To help that person make a decision based on their responsibilities, you provide both good and bad information together.

Tanaka-kun said.

The fairy nods.

“Yes.”

“You make the points where they most need to make a decision easy to understand.”

“That’s right.”

“Not just the benefits.”

“But also the drawbacks.”

“By comparing them.”

Yes.

Finally, place the materials that the person can use to make a decision.

Yes!

It was displayed in large letters behind the fairy.

✨ Change how you present things based on the person

📌 Do not change the facts

📌 Do not hide inconvenient information

📌 Provide more detail on the parts they are responsible for

Tanaka-kun nodded with satisfaction.

This will work.

When he combined the three versions, the proposal suddenly became compact.

Tanaka-kun and the fairy began the final organization.

First.

📄 Common Proposal

To that,

📘 Sales Decision Set for Manager Kuroda

📗 Technical Decision Set for Manager Shiroki

📙 Quality Decision Set for Manager Hoshina

are attached.

And then.

Compared to the one I made at first,

📚 the super-huge proposal

it is incomparable.

It's clean.

Tanaka-kun opens the first "dictionary".

Scroll.

Scroll.

Scroll.

Scroll.

"It's long..."

Next.

He looks at the newly organized proposal.

Common.

Sales.

Engineering.

Quality.

You can find what you need right away.

✨

Tanaka-kun couldn't help but smile.

"Even though it uses the same information"

Yes.

It looks like a completely different document.

The fairy also nods happily.

It's not so much the amount of information, but the way it's organized that has changed.

At first, I thought that including everything would make it more detailed.

Yes.

But when I made it detailed, it became so long that no one could read it.

Yes.

So I tried to trim it down.

Yes.

But it wasn't just about cutting things out.

Tanaka-kun points to the three people's requests.

I separated it based on who needs to see what.

The fairy smiles.

😊✨

It has finally returned from being a dictionary.

Tanaka-kun picked up the completed proposal.

And then.

He sat back down in his chair, looking satisfied.

A few seconds later.

"............"

Tanaka-kun sank back into his chair.

The fairy also sat on the desk.

"Tanaka-san?"

"I'm exhausted......"

"Me too......"

The proposal.

Had become quite compact.

His mind, too.

Had been quite organized.

However.

Only the two of them's stamina.

Had not recovered at all.

Chapter 9: The Worn-out Tanaka-kun and the Fairy Who Is Somehow Visible

"You didn't include everything again, did you?"

Tanaka-kun, having finished organizing the proposal, was completely worn out.

For Department Manager Kuroda.

For Department Manager Shiraki.

For Department Manager Hoshina.

I created versions for all three people.

From there, I extracted the common parts.

Furthermore,

📊 Comparison

⚠️ Disadvantages

✅ Decision-making criteria

I organized it down to this point.

It is incomparable to that thick "dictionary" I made at the beginning.

It has become much easier to read.

It has become much easier to understand.

And.

I am quite exhausted.

Tanaka-kun was walking while holding the completed proposal.

His steps were heavy.

"............"

The little fairy wasn't flying energetically as usual either.

At about the height of Tanaka-kun's shoulder,

wobbling.

wobbling.

"Tanaka-san..."

"Hmm..."

"Can you walk...?"

"I'm walking..."

"That's right..."

Both of them.

They were completely on the verge of running out of battery.

It was Hayashi-san who found Tanaka-kun like that.

"Hey, are you okay?"

Tanaka-kun slowly looks up.

"...Hayashi-san."

Hayashi-san makes a dubious face.

"What's with that face?"

"I was... making a proposal."

"I can see that just by looking."

Hayashi-san looks at the documents Tanaka-kun is holding.

Perhaps he had a bad feeling about it.

He frowns.

"Tanaka-kun..."

"Yes..."

Tanaka-kun froze.

"............"

Hayashi-san also froze.

"Hey"

"............At first"

"I knew it!"

Tanaka-kun waved his hands in a panic.

"No, no, no! I realized it halfway through this time!"

"Halfway through?"

"Yes!"

Hayashi-san looked at the proposal, still skeptical.

"What did you realize?"

Tanaka-kun straightened his posture just a little.

"At first, I tried to include everything the three department managers told me."

"Yeah."

"Then, it became incredibly thick."

"I bet."

"More than a proposal..."

Tanaka-kun looked a bit hesitant to say it.

"It turned into something like a dictionary."

Hayashi-san burst out laughing.

"A dictionary?"

"Please don't laugh."

"No, I just thought it was so like you, Tanaka-kun."

"You're not complimenting me there, are you?"

"I am not."

Tanaka-kun slumped his shoulders.

This time, he had stopped himself halfway through.

Sato-san came over as well.

"What are you two talking about?"

Hayashi-san replied.

"It seems Tanaka-kun did the 'all-inclusive' thing again."

Tanaka-kun corrected him immediately.

"Only at the beginning!"

Sato-san looked at Tanaka-kun.

"Only at the beginning?"

"This time, I realized halfway through that this wouldn't work."

Sato-san's expression changed slightly.

"Oh..."

Tanaka-kun opened the proposal.

Make the necessary parts common to all three.

He turns the page.

After that, the part for Manager Kuroda.

Next.

For Manager Shiraki.

Next.

For Manager Hoshina.

Sato-san receives the document.

He checks it in silence.

Tanaka-kun felt a little nervous.

Hayashi-san also peeks in from the side.

Sato-san said.

So you separated the common parts and the individual parts.

Yes.

What about the individual parts?

I included comparisons, disadvantages, and decision-making criteria for each.

Sato-san looks at the pages further.

Manager Kuroda is in Sales.

Yes.

Manager Shiraki is in Engineering.

Yes.

Department Manager Hoshina wants quality.

Yes.

A brief silence.

Tanaka-kun fidgets.

How is it?

Sato-san closed the document.

It's still a bit rough in terms of organization, but...

Tanaka-kun's shoulders slump slightly.

...Yes.

Sato-san continued.

However.

Tanaka-kun looks up.

Tanaka-kun's eyes widen slightly.

...Are you serious?

Before, you would have just put everything you researched in and called it a day.

Hayashi-san says from the side.

No doubt about it.

Hayashi-san!

Sato-san also smiles a little.

"This time, you stopped yourself halfway through, didn't you?"

"Yes."

"Then you're making more progress than before."

Tanaka-kun scratched his head, looking a bit embarrassed.

"I realized it after I'd already made it for all three of them, though..."

Hayashi-san replies immediately.

"You're still the same as ever there."

"So please praise me until the end!"

"But you're working harder than before, aren't you?"

Mayumi-san, who had been watching the exchange, opened her mouth with a small smile.

"But you're thinking about it more properly than before, aren't you?"

Tanaka-kun turns around.

"Mayumi-san."

"Because if it were before..."

Mayumi-san looks at Hayashi-san.

"You would have just crammed everything in and taken it as it was, right?"

Hayashi-san answers immediately.

"He did."

Tanaka-kun objects.

It's not that bad!

Sato-san chimed in from the side,

No, I think you probably did.

Even you, Sato-san! That's terrible!!

Mayumi-san laughed.

😊

But you realized it was strange yourself this time, right?

Well... yes.

Then that means you're growing.

Tanaka-kun was silent for a moment.

When someone says it so directly like that,

it makes me feel a bit shy.

...Thank you.

Hayashi-san was grinning.

You're unusually honest.

I'm just too tired to have the energy to argue back.

I see.

At that moment,

Mayumi-san shifted her gaze to the side of Tanaka-kun.

And then.

I said it casually.

"That must have been tough for you too."

Tanaka-kun stops.

Hayashi-san stops.

Sato-san stops.

"............"

Only Mayumi-san has a normal expression.

Tanaka-kun slowly opens his mouth.

"......You?"

"Yeah."

Mayumi-san points to the side of Tanaka-kun.

"AI Fairy-chan."

Tanaka-kun.

"............"

Hayashi-san.

"............"

Sato-san.

"............"

Fairy-chan.

"............"

A few seconds.

Tanaka-kun and the fairy-chan shouted at the same time.

"Eh? Isn't she an AI mascot character?"

Mayumi-san looked puzzled.

"Eh?"

Tanaka-kun points at the fairy-chan.

"Fairy-chan, can you see her?"

"I can see her."

"Since when!?"

"For a while now."

"For a while now!?"

Hayashi-san looks at Tanaka-kun.

"Hey, Tanaka."

"Yes."

"What are you talking about?"

Sato-san is also confused.

"I want you to explain it to me too."

Tanaka-kun looks at the two of them.

Next, I look at Mayumi-san.

"Hayashi-san and the others can't see the AI fairy."

Mayumi-san's eyes go wide.

"Eh?"

This time, Mayumi-san looks at Hayashi-san.

"You can't see it?"

"See what?"

Mayumi-san points at the fairy.

"It's right there."

Hayashi-san looks at the empty space.

"............"

Sato-san looks too.

"............"

There is nothing there.

At least.

To the two of them.

They can't see anything.

Hayashi-san said.

"Mayumi"

"What?"

"What do you see?"

Mayumi-san looked puzzled.

"An AI mascot character"

Hayashi-san.

"......Huh?"

Sato-san.

"An AI mascot!?"

"Yeah"

Mayumi-san looks at the fairy.

"You see these kinds of AI characters around lately, right?"

Tanaka-kun held his head in his hands.

"No, it's a little different from that..."

The fairy also makes a troubled face.

😥

"I also thought I was only visible to Tanaka-san."

Mayumi-san.

"Is that so?"

The fairy.

"Yes"

Mayumi-san.

Huh.

Tanaka-kun blurts out involuntarily.

That's a light reaction!

Fairy-chan complains to someone other than Tanaka-kun for the first time

Mayumi-san looks at Fairy-chan again.

But it must have been tough, right?

Fairy-chan tilts her head.

What do you mean?

Tanaka-kun.

Tanaka-kun turns around.

Huh?

Mayumi-san says with a completely normal expression.

Tanaka-kun is a hard worker, but

She smiles a little.

He also has a sloppy side, so it seems tough.

Tanaka-kun.

Wait a second.

Fairy-chan.

That's right!

Tanaka-kun.

"Huh?"

The fairy suddenly becomes energetic.

"It's really tough!"

"Fairy?"

"They don't give me the necessary information"

The fairy points at Tanaka-kun.

"Like 'make it look good'"

"............"

"Or 'you should know, right?'"

"............"

"Or 'you're an AI, so think for yourself!'"

Tanaka-kun panics.

"Hey, you don't have to bring up the past!"

Mayumi-san nods as if sympathizing with the fairy.

"That sounds tough."

"It really is!"

The fairy continues, seizing the opportunity.

"When I say there isn't enough information, they get angry!"

"............"

"And when I fill in the gaps with generalities, they tell me not to decide things on my own!"

"............"

"I was told it was too much after I included all the information!"

"That's not just my fault!"

"My brain is going to explode too!"

The fairy leaned toward Mayumi-san.

Tanaka-kun.

"Hey!"

Hayashi-san.

"............"

Sato-san.

"............"

To the two of them.

Tanaka-kun and Mayumi-san,

looked like they were just talking to empty space.

Hayashi-san whispered to Sato-san.

"...Can I go home?"

Sato-san replied in a whisper as well.

"I'd like to do the same."

"If you do that, she won't be Tanaka-kun's AI fairy anymore, will she?"

Mayumi thought for a moment.

"I don't mind helping, but"

The fairy's face brightened.

✨

"Really!?"

"Yes."

Tanaka-kun panicked.

"Wait a minute!"

Mayumi continued.

"However"

She tilted her head slightly.

"If I teach you everything"

Little fairy.

"Yes."

"Won't Tanaka-kun stop thinking for himself?"

The fairy froze.

"............"

Tanaka-kun also froze.

Mayumi said with a smile.

Yosei-chan.

"............"

Tanaka-kun.

"............"

For a while, both of them were silent.

Yosei-chan slowly looks at Tanaka-kun.

Tanaka-kun also looks at Yosei-chan.

"......Indeed."

"That's right......"

Mayumi-san smiles.

"It might be tough, but there's meaning in the two of you doing it together, right?"

Yosei-chan thinks for a moment.

And then.

😊✨

"Well then, I will try a little harder to train Tanaka-san!"

Tanaka-kun replies immediately.

"Don't call it training!"

Mayumi-san laughs.

Hayashi-san holds his head in his hands.

"So who are you talking to!"

Sato-san seemed to have given up on thinking about it anymore.

Hayashi-kun.

Yes?

Maybe it's better not to think about it too deeply.

I suppose so.

It's not perfect. But it's a step forward from before.

Tanaka-kun looks at the completed proposal once again.

It didn't go well from the start.

He crammed in all the requests from the three people.

It ended up like a dictionary.

He made three separate versions for each of them.

He created the same parts three times.

He was exhausted.

He remade it again.

He couldn't exactly call it efficient.

Even so.

This time.

Before someone,

told him,

Don't include everything.

I was able to stop myself halfway through.

I thought about who I was handing it to.

I consolidated the common information.

I separated the necessary information for each recipient.

And then.

Not just the benefits.

But also the drawbacks.

And the comparisons.

And the decision-making materials.

I decided to hand them over together.

Tanaka-kun closed the proposal.

"Well."

Hayashi-san looks at him.

"What is it?"

Tanaka-kun smiled a little.

"Can we just say it's a little better than before?"

Hayashi-san snorts.

"Though you only realized that after making three versions."

"Let's just leave that part alone!"

Mayumi-san laughs.

But you noticed it, didn't you?

Sato-san nodded as well.

That alone is enough.

Tanaka-kun puffed out his chest just a little.

The fairy, too.

Beside Tanaka-kun, she had a slightly proud look on her face.

😊✨

However.

Tanaka-kun and the others don't know.

At that time.

The three department managers.

With Tanaka-kun's proposal in hand.

Are starting to think of something again—.

Chapter 10 Final Chapter—The three department managers had evil looks on their faces again

The three compare Tanaka-kun's proposal

A few days later.

On the conference room table, the proposals Tanaka-kun submitted were lined up.

📄 The proposal common to all three

📘 For Sales Manager Kuroda

📗 For Engineering Manager Shiraki

📙 For Quality Manager Hoshina

It is not like the

📚 “dictionary” stuffed with everything

from before.

The information that all three of them need to know in common is consolidated into one place.

On top of that.

Sales.

Engineering.

Quality.

Only the information necessary for each person in charge to make decisions regarding their own area was separated.

Manager Kuroda first flips through the common section.

“Purpose of the project”

Flip.

“Customer issues”

Flip.

“The scope of decisions to be made this time”

He turns the page further.

And then.

He entered the page dedicated to Manager Kuroda.

📊 Comparison with competitors

⚠️ Sales disadvantages

✅ Decision-making criteria for proceeding to the next market validation

Department Manager Kuroda's mouth corners lifted slightly.

"...Huh."

Next to him, Department Manager Shiraki was checking his own page.

📊 Comparison of facilities and processes

⚠️ Anticipated issues during mass production

✅ Decision-making criteria for proceeding to prototyping and technical verification

Furthermore.

Department Manager Hoshina was also looking through the quality documents meant for him.

📊 Comparison with quality standards

⚠️ Variations, unverified performance, and warranty risks

✅ Decision-making criteria for proceeding to the next quality verification

All three of them.

remained silent for a while.

Only the sound of turning pages echoed through the conference room.

Flip.

Flip.

Flip.

Eventually.

Department Manager Kuroda closed the proposal.

"How is it?"

Department Manager Shiraki answered while still looking at the document.

"The parts I want to see are still there."

"And the unnecessary parts?"

"Minimal."

Department Manager Hoshina also nodded with a calm expression.

"This is also easy to understand."

Department Manager Kuroda looked at Department Manager Hoshina.

"Has the quality information been cut too much?"

"No."

Department Manager Hoshina pointed to his own page.

"For me to make a decision this time, this is sufficient."

"I see."

This time, Department Manager Shiraki asked Department Manager Kuroda.

"What about yours?"

"No problem."

Department Manager Kuroda tapped the sales page lightly.

"The differences from the competition are also there."

There are also weaknesses from the customer's perspective.

It doesn't just end with 'it looks like it will sell'.

He smiles a little.

It properly serves as material for me to make a decision.

I thought you were still a novice if you just included everything.

Department Manager Shiraki lined up the common parts and the individual materials for the three of them.

「The requirements I gave you at the beginning」

「Yes」

「It has decreased quite a bit」

Department Manager Kuroda laughs.

We said quite a lot, after all.

You were the one who said the most, weren't you?

Sales needs a lot of information.

Department Manager Hoshina smiles gently.

I also made quite a few requests, though.

Department Manager Shiraki looks at Department Manager Hoshina.

You were the one saying the most detailed things with a smile on your face.

It's about quality.

That's a convenient phrase.

The three of them laugh a little.

And then.

Department Manager Kuroda looks at Tanaka-kun's proposal once more.

"To be honest"

Department Manager Shiraki turns his face toward him.

"What is it?"

Department Manager Kuroda replies.

"If you just pack everything in as is and bring it here"

He pauses for a moment.

Department Manager Shiraki nods.

"Me too."

Department Manager Hoshina as well.

"I agree."

Department Manager Kuroda taps the common sections with his finger.

"But"

"It seems he realized it halfway through."

Department Manager Shiraki says.

"And he didn't just trim it down."

He looks at the three volumes in order.

I even separated who sees what.

Department Manager Hoshina continues.

Information that is inconvenient is also still there.

That's it.

Department Manager Kuroda nodded.

Sales disadvantages.

Technical issues.

Quality risks.

None of them have been erased.

Rather.

They were placed exactly where the person responsible for them needs to be most concerned.

What the three of them wanted was not the 'correct answer'.

Department Manager Shiraki crossed his arms.

"I could have taught him this format from the beginning, though."

Department Manager Kuroda laughs.

"That would be meaningless, wouldn't it?"

"I thought you'd say that."

Department Manager Hoshina looks at the two of them.

"But we weren't trying to get him to guess the correct answer, were we?"

Department Manager Kuroda nods.

"Ah."

Department Manager Shiraki continues.

"What is needed in a proposal changes depending on the company and the project."

"There is no point in just memorizing this current format."

Department Manager Hoshina says.

"What is important is..."

He pauses for a moment.

"Can you realize when there is too much information?"

"Can you think about who will make the decision?"

"If you don't understand, can you organize it again?"

Department Manager Kuroda laughs.

"That suits Tanaka better."

Department Manager Shiraki glances at him sideways.

"Are you planning to throw another task at him?"

"I haven't said anything yet, have I?"

"Your face says it all."

What Tanaka-kun learned this time

Meanwhile.

Tanaka-kun was staring blankly at a copy of the proposal at his desk.

Next to him, the fairy still looks a little tired.

"Fairy-chan"

"Yes"

"You know, this time"

"Yes"

"When the department managers told me so much at the beginning"

"Yes"

"I thought I had to include everything"

"That's right"

"I thought the more information, the better"

"Yes"

"But, when there's too much, I didn't know what I should be looking at"

Fairy-chan nods.

Tanaka-kun holds up one finger.

☝️ First.

"More information isn't always better"

Second finger.

✌️ Second.

"Even for the same project, different people need different parts"

Third finger.

🤟 Third.

Make what is necessary common to all three.

The fourth point.

Separate the parts that only that specific person needs to know in detail.

The fairy continues.

Furthermore.

Tanaka-kun looks.

What?

The fairy displays three items.

📊 Comparison

⚠️ Disadvantages

✅ Decision-making criteria

Not just the good points.

Also the bad points.

Also the material for comparison.

Finally, the material that allows that person to make a decision.

Tanaka-kun nods.

That's right.

The fairy smiles a little.

😊

We were able to organize it quite well this time.

Tanaka-kun laughs too.

"Though that's only after making three volumes."

"Yes."

"You should deny that."

"Because it's a fact."

"That again?"

Using AI makes things faster. But it doesn't mean you don't have to think.

Tanaka-kun put on a slightly serious face.

"Also."

"Yes."

"The thing that surprised me the most this time."

"What is it?"

"Was that by the second and third time, it became incredibly fast."

The fairy nods.

For Department Manager Kuroda.

What should be compared?

What should be considered a disadvantage?

What constitutes decision-making material?

The two of us thought about that together.

For Department Manager Shiroki.

I was able to use the procedure I created once.

And then.

For Department Manager Hoshina.

It proceeded almost entirely with just code words.

Tanaka-kun says.

"It's amazing how once you do a similar task, the next time goes faster."

"Yes"

"Once I tell the AI how to organize it"

"Yes"

"And I learn how to do it"

"Yes"

"The second and third times, it gets shorter and shorter."

The fairy nods.

"However"

"Yeah?"

The fairy looks at Tanaka-kun.

"Tanaka-san, you were extremely exhausted."

"That's true."

Tanaka-kun rested his elbows on the desk.

"Even though the time is getting shorter."

"Yes"

"My head was getting more and more tired"

"Because I was constantly making decisions"

1. Comparing.

2. Choosing.

3. Cutting.

4. Keeping.

5. Confirming.

6. Correcting.

7. Making decisions again.

8. AI responds immediately.

That's why.

Thinking again immediately.

Tanaka-kun let out a small sigh.

The fairy nodded.

"I can provide the material for thinking quickly"

"Yeah"

"I can also organize it"

"Yeah"

"But, what should we adopt?"

"Yeah."

"Who should see what?"

"Yeah."

"The one who decides in the end is you, Tanaka-san."

Tanaka-kun gives a wry smile.

"In the end, I have to use my own brain too, huh."

"Yes!"

"Don't say that so cheerfully."

From 'increasing information' to 'selecting information'

Tanaka-kun remembered the thick proposal he had made at the beginning.

Back when there was little information.

He was trying to gather information at any cost.

Researching things he didn't understand.

Gathering primary information.

Passing it to the AI.

That was necessary.

But.

After the information increased.

Another problem was waiting.

What should be used?

What should not be used right now?

Who is this for?

How much detail should be shown?

Tanaka-kun says quietly.

"It doesn't end just by gathering it all, does it?"

The fairy nods.

And then.

What was needed after having a massive amount of information was,

not to increase the information even further.

It was to select information according to the purpose.

Tanaka-kun had finally reached that point.

And the three department managers—

Once again.

The conference room.

Department Manager Kuroda placed Tanaka-kun's proposal in the center of the desk.

"Well then."

Department Manager Shiraki makes a disgusted face.

"What is that 'well then' for?"

This is as far as we got this time.

I see.

In that case,

Department Manager Kuroda pulled out another document that had been sitting next to his desk.

Department Manager Shiraki narrowed his eyes.

...You.

Department Manager Hoshina also looked at the document with interest.

Is this the next task?

Department Manager Kuroda laughed.

😏

Since Tanaka has finally reached the point where he can think this far.

Department Manager Shiraki sighed.

You're planning to make him do something else again, aren't you?

The next step is one level higher.

Department Manager Hoshina, too.

With his usual calm expression.

Just a little.

He wore a mischievous smile.

😏

Then, this time—next—

Manager Kuroda.

Manager Shiroki.

Manager Hoshina.

The three of them look at the documents on the desk.

And then.

They looked at each other.

On the faces of the three.

Once again.

A joyful smile appeared.

😈✨

Meanwhile, Tanaka-kun.

Completely unaware of any of that.

Sunk deep into his chair at his desk, he was saying to the fairy.

"I don't want to see a proposal for a while..."

The fairy also answers while sitting flat on the desk.

"Me neither..."

Tanaka-kun.

"Next time, I'd like a slightly easier job."

The fairy.

"Well, yes..."

Both of them.

From the bottom of their hearts.

They wished for that.

However.

Whether that wish would come true—

Only the three department managers knew.
