(1) "Management" Summary Page

This page summarizes articles related to management.

In system development projects, you need not only technical skills but also the ability to move work forward, communicate, make decisions, and involve others.

I have written articles about what went well, what failed, and what I realized later while working on troubled projects and large-scale development sites.

On this page, I have organized useful articles by theme for those who are managing for the first time, those aiming to become PLs or PMs, and those struggling with team or work processes. I hope you will read from the themes that interest you.

1. Where to start | Management Basics

These are the essential articles I want those who are managing for the first time or those who want to improve their practical skills in a short period to read first.

Improve Your Management Skills! (1) The Most Important Management Method in System Development

I would love for people like this to read it!

The reason work doesn't move forward is "size"—The art of manageable design

A must-see for those who often have their work requests rejected!
What is the "manageable size" that is the key to this? Please take a look.

The true nature of "not getting through" is "ambiguity"—How to eliminate gaps by concretizing instructions

"I thought I communicated it properly, but it didn't get across as I intended." The cause might not be the other person, but ambiguous instructions. I explain how to communicate to reduce gaps, which can be used for both AI and people.

Why does "I taught them, but they can't do it" happen?—The true nature of the "structure" that causes training to collapse

When you feel "I taught them, but they can't do it," the cause might not just be the other person's ability. I organize the structures where training fails and explain the perspectives that leaders should review.

2. Design to move work forward

What is important in management is not just giving instructions.
It is important to adjust the size of the work and make the purpose and progress clear so that the other person can start without hesitation.

Here, we summarize ways of thinking to move work forward by viewing the causes of work stoppages not as "lack of ability" but as "design problems."

The wall of explanatory power that talented engineers hit when they become leaders

"I've researched and explained it properly, so why isn't it getting through?"
The reason for this may be that the ability to decipher details and the ability to convey them to others are two different things. We have organized the evaluation criteria that change when an SE becomes a leader.

[Failure and Improvement] On the issue of suddenly starting to talk about details, leaving everyone blank-faced

In meetings for problem-solving tasks, there are times when people suddenly start talking about details, such as saying,
"We must do this for such-and-such."
If you start talking suddenly without an agenda, without materials, and with
nothing displayed, it often leads to a situation where people think, "What are you talking about?."This happens frequently in failing projects, but what should be done about it?

[Failure and Improvement] Communication breakdown caused by mentioning everyone

Have you ever mentioned "@everyone" or "@team" on Teams or Slack and received no response from anyone? Regarding this, I have examined improvement plans by dividing it into:
[Problem 1] Diffusion of responsibility
[Problem 2] Writing is not the end

The real reason chat drags on—the "3-exchange rule" to stop misalignment

In chats like Teams or Slack, there are times when you exchange messages many times but still don't understand or reach a conclusion. This isquite damaging.

3. Adjusting team atmosphere and motivation

Many problems in projects start from slight misalignments in understanding.
The order of chats, mentions, meetings, and explanations. They all seem like small things, but if left alone, they lead to major rework and dissatisfaction.

Here, we have compiled articles to help you improve your daily communication a little and move your work forward smoothly.

[Real Experience Report] Motivation boost! Tips for success with thank-you cards

A highly effective, zero-costthank-you card.
We have summarized the tips for success and reasons for failure.

A talented hawk hides its "thoughts"

With harassment regulations becoming stricter, people have become extremely sensitive about pointing things out to others.
Because of this, some people intentionally say nothing to others and focus solely on self-improvement...
Read the rest in the main article!

Tough but fundamentally solvable: How to face anxiety and dissatisfaction

What do you think is important for fundamentally solving anxiety and dissatisfaction?
⇒⇒⇒ Actually, the order in which you tackle them is important.
What is that order?

4. Training judgment and logical thinking

In management, making decisions based solely on intuition can lead to failure.

Why do you think that way?
Where is the problem?
Is that conclusion really correct?

Here, I have compiled articles for thinking logically and improving the accuracy of your judgments.

Logical Thinking Practice (1) - Why shouldn't you blame others?

"You shouldn't blame others."
This is often said from a moral standpoint, but can you explain it logically?
Please check the logic used to reach this conclusion.

Logical Thinking Practice (2) - Is content business profitable?

"Is content business profitable?"
I compared my conclusion with AI's conclusion.
Counterarguments were also verified, leading to a surprising result.

Logical Thinking Practice (3) - Why can't Japanese companies reduce wasteful meetings?

"This meeting is long, I wish it would end soon"
There must be many people who think this way, so why don't they try to improve meetings? I explored that mystery.

Don't worry about hindsight

Isn't there someone who says "I was against it" when things don't go well later on?

You can say anything in hindsight.
Even if the words themselves were correct, if you don't listen while understanding the context, you will make the wrong judgment.
I have written about this topic in depth.

I thought logically about whether or not to start Kindle Unlimited

Conclusion: Start Kindle Unlimited!
Why did I reach that conclusion?
I thought about it from three points of view.

5. Reflection, Habituation, and Continuous Improvement

A method that worked once won't necessarily work forever.
What's important is to reflect periodically and apply both successes and failures to the next step.

Here, I have summarized articles related to reflection, habituation, and continuous improvement. Recommended for those who want to gradually develop their management skills.

I realized that reflection is indeed important

Reflection, which is surprisingly often underestimated.Reflection.
I think it's hard to find time to reflect on the past because you're chased by the next things you have to do, butsuccessful peopleseem to bedoing it often.
I have written an article again about the importance of reflection.

The logic of a genius (1) Decide to do it, (2) Do it, that's all. (Juni Taisen) No, I don't get it

"Why can that person do it well, but I can't?"
The processing flow was different between a genius and an ordinary person.
So, what should I, an ordinary person, do?
There was a method that even an ordinary person could do!

I want to rewrite, I want to rewrite, I want to rewrite

Sometimes I, too, can enter a state of "genius logic."
"Genius logic: 1. Decide to do it, 2. Do it. That's all."
Please read this in conjunction with that!

6. Career and Life Strategy from a Management Perspective

Management concepts can be applied not only to work but also to your career and life.

Where should you spend your time?
What should you prioritize?
What risks should you avoid, and what kind of future should you choose?

Here, I have compiled articles that consider management positions, annual income, health, and life planning from a management perspective.

People who want to be managers: 86% in India and Vietnam, 21% in Japan

There are few people who want to be managers.
This is striking when compared to other Asian countries.
"Is Japan going to be okay like this?!"
It might actually be an emergency situation.

Life Strategy from Age 50: How to Design Your Life as a "Project"

"At this rate, I might end up having failed at life planning"
I thought about this at age 44, in a hospital bed after surgery.
How did I plan my life after that?
I have systematically summarized the methods I gained for designing life as a "project" up until I went independent and founded my company five years later👇

Does not working overtime actually increase your income? The cost of health risks

In these cases, overtime is a no-go.
⚠️ If you start getting irritable from lack of sleep or stress
⚠️ If your family starts complaining
⚠️ If you don't have a long-term strategy
I will explain each of these in detail.

I realized once again how amazing Amazon is (I'm a little intimidated)

World-class companies are incredible!!
Their serious sense of speed is seriously insane.
I wrote an article about such an event.

Are you still changing your password every month? Security pitfalls that management doesn't know about

Does your company still require employees to change their passwords every month?
If so, please consider reviewing this policy.
It is highly likely that this is weakening security and incurring unnecessary costs.
