Document Creation Techniques of Foreign Consultants: 'Structure' Matters More Than 'Appearance'
"Why is that document so easy to understand?"
People who have seen decks (presentation materials) from foreign consulting firms like McKinsey, BCG, Bain, Accenture, or Deloitte often feel this way. It is not that there is an excessive amount of text, nor is the design particularly elaborate. Yet, after looking at it, the core message remains clear.
Conversely, when looking at documents created in-house, one often encounters situations where "the slides are packed with text but I don't know what they are trying to say" or "there are graphs but I don't know what they represent." Even with abundant data, the viewer is left without a clear sense of "what am I supposed to do with this?"
This difference is not about design sense. It is a problem of the document's "structure."
The techniques that foreign consultants practice in document creation are a collection of systematic methods that can be learned consciously. In this article, I will thoroughly explain these techniques by dividing them into the "layer of thinking" and the "layer of creation."
Why do consultants' documents "get the message across"? — The fundamental difference
Before getting into the technical aspects, let's understand the fundamental difference in mindset.
Most people pack their documents with "what they know, what they have researched, and what they have thought about." This is a "sender-perspective" document. The creator understands the meaning, but the recipient is left with the question, "So, what are you trying to say?"
Consultant documents are created from a "receiver-perspective." Working backward from "what judgment or action the person viewing this document should ultimately take," they present only the necessary information in the necessary order.
This "backward-thinking approach" is the core of consultant documents.
"Who is reading this (audience)," "what state are they currently in (context)," and "what do I want them to decide through this document (goal)"—if these three points are not clear, no amount of design will make sense.
There is something consultants always do before creating a document. It is the self-questioning of repeating "So What?" and "Why So?" "What is the reason for showing this data?" "What can be said from this analysis?" "What do I want the other party to do in response?"—elements that cannot answer these questions are deleted from the document.
Technique 1: The Principle of "One Slide, One Message"
The first thing you notice about consultant documents is the low density of the slides. A graph, a few lines of text, and that's it—these slides follow one after another.
Many people think, "Is it okay to have so little information?" but this is an intentional design. If you pack multiple messages into a single slide, the reader's gaze and attention become scattered, and eventually, they lose track of "what is important."
The principle of "One Slide, One Message" is the rule of placing only one "claim" on each slide. That message should be written as a complete sentence in the title section (header) of the slide.
For example, the title "Third Quarter Performance" is just a "topic," not a "message." This conveys nothing to the viewer. "Third-quarter sales increased by 15% year-on-year, exceeding the plan by 5%"—this is a message.
This technique is called an "Assertion Title." It is a state where the slide title is a sentence with a verb and a subject that expresses "what I want to say" rather than "what it shows."
By thoroughly applying assertion titles to all slides, the "structure of claims" of the entire document becomes visible. If you read only the slide titles, you can follow the claims of the entire document—this is the ideal form of a consultant's deck.
Practical Tip: After writing the title, check if you can say "therefore, what should be done or what can be said" in one sentence. If you cannot, the title is not a message.
Technique 2: Design the entire document using a pyramid structure
Not only individual slides, but the entire document structure also requires a 'logical skeleton.' Consultants design the entire deck using a 'pyramid structure.'
At the apex of the pyramid, one 'main message (what you want to convey throughout)' is placed. In the layer below, 'evidence supporting the main message (about 3 to 5 points)' is lined up. In the layer below that, 'data, facts, and analysis results' that support each piece of evidence are placed.
Documents that lack this structure end up in a state where 'various facts and data are lined up, but it is unclear what can be concluded from them.' Even if the data is sufficient, the apex of the pyramid (the conclusion) is missing.
Steps for document design
Before creating a deck, consultants first create a 'storyline (an outline of the slide flow).'
Write the main message in one sentence: e.g., 'We should focus on the XX business,' 'We need to change the cost structure'
Identify 3 to 5 points of evidence to support that message: Organize 'why that can be said' in a MECE manner
Identify data, facts, and analysis to support each piece of evidence: Necessary graphs, numbers, and case studies
Consultants perform this work in Excel or a notepad first, and only open PowerPoint after the skeleton is set—this is a golden rule for consultants. 'Thinking after opening PowerPoint' is the worst way to create a document. Your thinking gets pulled by the constraints of the tool, and it becomes a 'task of filling in' slides.
Technique 3: Graphs are for 'visualizing the message'
Many people believe that 'using graphs makes things easier to understand.' However, in reality, I frequently see documents where 'it somehow became harder to understand after turning it into a graph.'
Consultants have clear principles for graphs.A graph is a 'tool to visualize a message,' not a 'tool to show data comprehensively'.
If 'what you want to say from this data' is clear, the type of graph, display range, color usage, and title are all optimized to convey that message. With the mindset of 'I want to show all this data,' a graph becomes nothing more than a container for data.
How to choose the type of graph
Want to show changes over time→ Line graph or bar graph (time on the horizontal axis)
Want to show proportions/composition ratios→ Stacked bar graph or pie chart (however, consultants prefer stacked bars because pie charts are difficult to compare)
Want to show the correlation between two indicators→ Scatter plot (bubble chart)
Want to compare the magnitude of multiple items→ Horizontal bar graph (arranging in descending order makes the maximum and minimum clear)
Clearly state the message in the title
Use 'action titles' for graph titles as well. Instead of 'Sales Trends,' write 'Sales have grown at an annual rate of 20% over the past three years.' Ideally, the reader should know 'what should be seen' the moment they read the title before looking at the graph.
Technique 4: SCQA—Designing a story from situation to issue
For large proposals and strategy documents, you need not only data and logic but also a 'story that draws the reader in.' The story design framework used by consultants is 'SCQA'.
S (Situation): Confirm the situation or facts that the reader already knows and agrees with. Create empathy here by making them think, 'Yes, that's exactly right.'
C (Complication): Show the problems, changes, or issues that have newly arisen in that situation. This is the part where a turning point like 'However...' or 'But...' is introduced.
Q (Question): The question that naturally arises from that problem. It is the form of a question that would pop into the reader's mind, such as 'So, what should we do?' or 'What is the cause?'
A (Answer): The answer to that question becomes the main message.
Let's look at an example.
S: 'Our flagship product holds a 40% share of the domestic market, maintaining the top position in the industry.'
C: 'However, due to the influx of low-cost competing products from the Asian market, the overall market price has fallen by an average of 15% over the past year.'
Q: 'How should our company respond to this price competition?'
A: 'The best strategy for our company is to avoid price competition and focus on high-value-added segments.'
With this SCQA flow, just by reading the first page of the document, it becomes clear 'why this document is necessary,' and the reader naturally becomes eager to know the 'answer.'
Technique 5: Convey everything first with an 'Executive Summary'
When creating long documents (20–30 pages or more), consultants always place an 'Executive Summary' at the beginning.
An executive summary is a condensation of the document's main conclusions, findings, and recommendations into 1–2 pages. Executives often have limited time and may not read every page. The design must ensure that by reading only the summary, one can fully understand 'what this document is trying to say.'
The structure of an executive summary is a summary of 'the top of the pyramid -> the 3–5 supporting points directly below it' on 1–2 pages. Detailed data and analysis are included in subsequent pages, designed so that 'those interested in the summary can proceed to the detailed pages.'
In documents from Japanese companies, there is often no executive summary (or there is a 'summary' at the end). However, in the consultant's philosophy, 'conclusions come first'—a document where the conclusion cannot be understood until the end wastes the reader's time.
Technique 6: 'Subtraction' in design—everything depends on what you omit
One of the reasons consultant documents feel 'clean' is their **thorough 'subtraction design.'**
Keep the elements in your slides to a minimum. Decorative borders, gradients, elaborate animations, and colorful designs—these are all extraneous elements that 'attract attention but hinder the understanding of the content' and should be eliminated.
Basic Design Rules Followed by Consultants
Limit fonts to two types: Stick to just two types: one for headings and one for body text. Having too many font types makes the visual presentation noisy.
Limit colors to three: Stick to three colors: a base color (white), a text color (black or dark navy), and an accent color (one color). Use the accent color only to 'highlight the most important information.' Too many colors make it impossible to tell what is important.
Keep text per slide within 200–300 characters: Slides are meant to be 'seen,' not 'read.' Lining up long blocks of text creates pressure to 'read it,' which distracts the audience's focus.
Use a grid to unify alignment: By aligning text, graphs, and diagrams to a grid, you create an 'orderly' impression on the slide. Misaligned layouts give the impression that 'this person is sloppy.'
Do not fear white space: White space is not 'empty space' but a 'design element that guides the eye.' When there is white space around important information, that information stands out.
The role of design is not to 'make things beautiful' but to 'help the audience understand the message.' From that perspective, you realize that 'subtraction' is the most important design skill.
Technique 7: Thorough 'So What?'—Giving Meaning to Every Element
Showing data, using graphs, including tables—these are all just 'means.' Consultants constantly ask 'So What?' about every element in their documents.
'I am including this graph to show X,' 'I am including this table to enable a comparison of Y,' 'I am including this case study to demonstrate the feasibility of Z'—if you cannot answer the 'reason for existence' of every element, it should be deleted from the document.
Documents created with the mindset of 'I worked hard to research this, so I'll include it' or 'It's a waste not to include all the data I analyzed' may have a lot of information, but they fail to answer 'So what?' Consultants actually prepare with the resolve that 'most of what I researched will not be included in the document.'
The quality of a document is determined more by 'what you cut' than by 'what you included.'
You can only have the 'courage to cut' if the 'goal of the document' is clear. If the goal is to 'decide between Plan A and Plan B,' then details about Plan C or raw market research data are unnecessary. If the goal is clear, you can naturally judge what should be cut.
Technique 8: The Culture of Review—Don't Just 'Make and Finish'
A culture that is thoroughly ingrained in foreign consulting firms but rarely seen in Japanese companies is the 'strict document review.'
Once a document is completed, someone other than the author must perform a 'review.' The reviewer points out issues from the perspective of 'Does the logic of this document hold up?', 'Is the data usage correct?', 'Is the message in the title appropriate?', and 'Can it be understood when read from the client's perspective?'
Reviews involve not just correcting typos, but essential feedback such as 'The So What in this graph is weak,' 'The messages on slides 5 and 7 are contradictory,' or 'The S in SCQA is too long and the reader will get bored.'
Without this review culture, a consultant's document quality cannot be maintained. A document must not be something that 'the person who made it understands,' but something that 'the person who receives it understands.' To achieve this, it is essential to have it checked by eyes other than the author's.
If you are working alone and have no reviewer, a simple method of 'reading it again the next morning after completion' is also effective. Immediately after creating it, you have the illusion that 'I understand it,' but if you leave it overnight and read it again, parts where you think 'I don't know why this graph is here' will become visible.
Practical Application: The Document Creation Workflow
Now that you understand the eight techniques, let's organize the actual document creation process. Consultants do not "start thinking after opening PowerPoint." They proceed with the following steps.
Step 1: Confirm the Goal (5 minutes) Clarify "who" will read this document, "when," and "for what purpose." You need specificity, such as "providing material for decision-making to the executive board for Thursday's meeting."
Step 2: Create a Storyline (15–30 minutes) Without opening PowerPoint, think about the slide structure using a notepad or whiteboard. Organize only in text: "What to say first, what evidence to show next, and what action to request at the end." The time spent struggling in this step will dramatically shorten your later PowerPoint work.
Step 3: Create Slides (Main Work) Once the storyline is solid, create the slides in PowerPoint. Write the action title for each slide first, then place the evidence (graphs, data, tables) that supports that title. Simply following the rule of "writing the title first" significantly lowers the risk of creating "slides where the point is unclear."
Step 4: Review the Overall Flow (10 minutes) Read only the titles of all slides in sequence. Check if the connected titles form a "story." Check for contradictions, leaps in logic, or redundancies.
Step 5: Review (Fresh Eyes) If possible, have someone else review it. If that is difficult, "reading it again the next morning" can serve as a substitute.
Common Patterns of "Disappointing Documents": Learning from Mistakes
To understand document creation techniques more deeply, let's organize the patterns of "what not to do."
Pattern 1: A Series of "5 Bullet Points" Slides Documents filled entirely with bullet points like "- XX," "- YY," and "- ZZ" hide the message. Bullet points are a "list of elements," not a "logical structure." After stating the message in the action title, use bullet points as evidence for it.
Pattern 2: Graph Titles Like "Trends in XX" As mentioned above, "Trends in XX" is a topic, not a message. This type of title is the reason why people are left thinking, "So, what was the point?" after looking at a graph.
Pattern 3: Presentations Ending with "That is all. Any questions?" Just writing "End" on the final slide leaves the audience wondering, "So, what should I do?" It is a consultant's ironclad rule to always clearly state the "next action (who, what, by when)" on the final slide.
Pattern 4: No "Bridge" Between Slides There are documents where each slide is understandable on its own, but the audience doesn't know "why the topic changed" when moving to the next slide. Simply adding a brief remark (transition) at the beginning of each slide, such as "Building on the previous slide, let's now look at..." will significantly improve the overall flow.
Summary: "Document Creation is the Visualization of Thought"
Let's summarize the eight techniques.
One Slide, One Message: Clearly state the message with an action title
Pyramid Structure: Design the storyline before opening PowerPoint
Graphs are Tools to Visualize Messages: Optimize type, title, and color for the purpose
SCQA: Engage the reader with a story of Situation → Complication → Question → Answer
Executive Summary: Put the conclusion at the beginning, and details on subsequent pages
Subtractive Design: Use only two fonts, three colors, and make effective use of white space
Thorough 'So What?': Be able to explain the 'reason for existence' of every element
Review Culture: Always have someone other than the creator check the work
The common thread among these is that 'document creation is the visualization of thinking.' The essence of document creation is the process of converting the ideas in your head into a form that allows the recipient to take action.
By consciously practicing these techniques one by one, the quality of your documents will certainly improve. As a first step, try changing the titles of all slides in your next document to 'action titles.' You will be able to experience for yourself just how much that alone changes the structure of the document.
The quality of a document is a mirror that reflects the 'quality of thinking' of the person who created it. Someone who can create easy-to-understand documents is valued as someone who can think in a structured way. Document creation skills are a universal asset for business professionals, regardless of job type, industry, or position.
'Good documents are born from good thinking. Good thinking is born from good questions.' The reason consultants keep asking 'What is the purpose of this document?' before they start creating it is precisely because they live by this principle.
