Business profit simulation class (Final exam)

Final exam case was announced last week.

The students are required to complete their own business financial plan and give an individual presentation in two weeks.


This is the case:


There is no “right” answer but the plan must be feasible and reasonable while meeting all the business requirements given in advance.


They have already learned the techniques to develop a business financial plan.

Making reasonable assumptions and adjustments to meet the requirements are the key!


Good luck and enjoy it !




Final exams at Yokohama National University

I have announced two final exams of the classes I have at Yokohama National University.

  • Business Logics and Team Consensus


・Business Problem Solving Logics and Frameworkfinal-presentation-announcement-problem-solving

Every student is assigned to a team and they still have two weeks to prepare for the final team-presentation.

I am looking forward to their excellent outputs.


How do you make sure of the MECE structure?

Keeping MECE (Mutually Exclusive and Collectively Exhaustive) is one of the biggest challenges for applying the logical thinking concepts for practical issue-solving.


In my class, students learn how to develop a logic tree while keeping the MECE structure in a practical way.


One of the tips is using “Pair concept” for coming up with possible alternative ideas.

The concept logically leads to a solid logic tree as follows:


Once you have an idea of possible cause (in the chart above, “Promotion was not effective”), you may draw an alternative cause by asking yourself “WHAT IF this is not a cause”.


In the chart above, the alternative is “Price up”.


Similarly you may repeat the same practices until you cannot come up with any other ideas.

In addition to the simple “pair concept” practice, you may apply the “category approach” as follows:



The words in blue in the chart above show “category names”, while descriptions in the white boxes are possible causes.

Using “Category names” allows you to lead alternative ideas much more easily by applying the pair concept to the category itself, rather than to the possible causes.


In my problem solving class, students repeat this excercises until they can make a solid tree showing all possible causes logically. It does not take much time, only a couple of practices are required.








Business management (Profit simulation) class at Yokohama National University VOL2

This is another video from my class “Business management with accounting and finance” at Yokohama National University for the international students.

Students are developing their own financial plan(simulation) for the business with Excel.

This is a technique I used to use in Nissan to propose a new business and/or new affiliate companies to the executives including the CEO.

You can make a profit simulation to see when and how much profit you will get in a certain year in the future with a variety of assumptions.

It is extremely practical, which you cannot learn at an ordinary schools or universities.


I would be happy to conduct an intensitve course (a few days/ a week etc.) in you need the program.

Business management (Profit simulation) class at Yokohama National University VOL1

A video from the“Business management with accounting and finance” class at Yokohama National University.

This is a very practical class for student to learn how to develop a business profit simulation by Excel.
Not only a simple profit simulation but also scenario analysis and senstivity analysis are discussed for the risk assessment.
Please contact me if you are interested in the program.

Profit simulation class to launch at Yokohama National University

This monthe, as an intensive program, I will launch a new class, ” Business management with accounting and finance” at Yokohama National Univesity.


In the class, students will learn how to develop a busines profit simulation with Excel.

You have to justify your business plan( and its profitability) to a final decision maker to get an approval.

You will always be required to propose how profitable the new business will be based on your simulation, whih shows how much profit you will and when.

In the class, the students will also learn how to simulate its potential risks in a qunatitative ways(with Excel).

I am very excited to launch the new class and would be happy to conduct the class at your company/university even outside of Japan.


4 KEY REQUIREMENTS for your logic development

When you develop your argument (message or conclusion), you have to meet four requirements in order to make your story convincing/logical.

This is a memo from my class of “logical problem solving”  at Yokohama National University:

Key requirements

First, you need to make clear what you need to address to directly support the conclusion. For example, I asked my students to develop their logic to support the following conclusion:

“Yokohama National University is the best school”

Many students, as I had expected, listed many reasons to show “the university is a GOOD university or BETTER university”, neither which is a direct answer to the original issue/conclusion. In order to support it, you need to show why you can say it is THE BEST, for which you need to show uniqueness of the university, not just showing good points or better points.

Second, when you address some reasons to support the conclusion, you need to make sure that the reasons meet MECE requirement. If you miss, even unconsciously, any critical reasons, it makes your argument very weak to convince somebody. In other word, it needs to be comprehensive.

Third, in addition to the comprehensiveness, those reasons need to be objective. Sometime you may rely on your own experience, which is very personal and limited in general. Reasons to show should be more general and objective so that you have convincing reasons.

Finally, even if you prepare many “good ” reasons, they need to logically and directly support the conclusion. Still many people make a common mistake of “logical jump”. In such case you need to show some more layers between the reason and conclusion to bridge the gap.

Also, the reason may only partially support the conclusion and you may need to have more direct reason(s) to the conclusion. You may use some “logical thinking” techniques to reinforce the connections.

Your presentation, discussion, negotiation and communication will be much more convincing and logical when you are aware of the requirements above, when you make your logic.

I would like to help you apply those concepts to practical problem solving, especially in business setting.
