## A good word to show the level of data aggregation.

My business statistics class started at Yokohama National Univerisy for the international students from all over the world.
Just to explain some basics for the new students, I was struggling to show the level of aggregation of data in my class.
This is a concept that you need to learn for managing data itself before studying some statsitics.
Today I found the word “granularity”.
I guess it is not that common word even for English speakers but it really fits the concept.

## Business logics class at Yokohama National University

The semester has just finished at Yokohama National University.

• Business logic and team consensus
• Problems solving

Good job! See you somewhere in the world!

I would be happy to give my lecture(s) of “practical” business logic making (for communication, negotiation and presentation etc.) for your company, university and many kinds of organization.

## How you can develop your facilitation(team discussion) & problem-solving skills in a university program.

We will spend two weeks to tackle the following exercises in a team.

This is for the “Logical thinking” class:

This is not an individual exercise and you need to reach an agreement with your team members, which is exactly the same situation you will face in a company.

You may be required to use almost all the techniques(i.e. facilitation skill & logic development skills) to make an answer.

And this is for “Problem-solving” class:

This is a comprehensive exercise where all the skills learned in the class will be required to get a practical solution.

I am really excited to know how my students will use their skills learned in the class and lead to a “high-quality” answer.

## How you properly summarize your observations? (Induction)

Induction was the main topic in my “Business Logics and Team Consensus” class at Yokohama National University in Japan for the international students.

The first exercise at today’s class was to make a summary of the following three statements:

• Japanese is busy
• Japanese is punctual
• Japanese acts quickly
• Japanese is always in a hurry

It seems that they all make a sense.  But wait a minute!

For instance, “Japanese is busy”…. Acting quickly does not necessarily mean the person is “busy”. The conclusion comes from such assumption which is not drawn from the real observation or fact.

Such mistake makes your logic weak.

As one of the techniques you should remember when you develop your logic using induction, ask yourself about the assumption(s) you make. If the assumption(s) is valid, you may have no problem in your story..

Here are some other exercises in the class today.

An answer to the question above is as follows:

:

This is not an only the answer. But I felt that the students were getting more skilled to construct their ideas logically.

This was the last exercise for today, which took more time to reach to the answer:

Today’s points were:

Don’t add your assumptions too much when you make a conclusion by summarizing your observations. Try to be based on the facts only.

## How can you fix your “logic jump” in your argument?

“Logic jump” was a main topic in my Class  “Business Logics and Team Consensus” at Yokohama National University today.

Many people make mistakes when they develop a logic (or simply to say, message).

You may skip some necessary explanations or assumption you make, which causes misunderstanding and mis-communication.

They are simply explained in the following two cases:

CASE 1 is generally called “Deductive method”.

In your daily conversation, you may never clearly mention any principles, rules which are already known by anybody and are called a”Major premise”.

But what if the major premise is wrong or not the same as other people……??

Sometimes it is a powerful method to clarify the gap of the premises with others so that you make your message.conclusion more reasonable, convincing and logical.

CASE 2 is a common pitfall of skipping some layers of the logic (logic jump).

You may need to fill the gap between a conclusion and reason(s) so that other people can understand how you reach the conclusion. In many cases you may know how you reach it but others may not. By clarifying the “missing” layers, you can reinforce your story/logic significantly.

Here are some exercise, our students tackled as a team in my class:

There is not a single “right” answer but it is quite important to think what are missing and how you can strengthen your logic.

The teams competed with one another in the class and enjoyed the competition so much!

Keep on studying hard!

## “Business Logics and Team Consensus” class at Yokohama National University

“Business Logics and Team Consensus” is designed for undergraduate studnets at Yokohama National University in Japan.

I made the program for the students who need busines skills to develop a logical conclusion individually or as a team. The new semester just staeted last week for English-speaking students from all over the world.

In this class, the students are required to learn how to develop thier arguments logically as communication, negotiation, presentation and planning skills in any kinds of business settings.

The class will follow the four principles described in the chart above: (1) through (4).

In the next class, we will discuss the point (1) above (The message/final conclusion is clearly defined).

My class is extremely practical so that they can use the skills very practically in the real business world. It contains lots of practical exercises.

Many people may start to tackle logic development once those conclusion is given.

But wait! It is too early and you may get lost in the later stages.

For example, when you see the statement “Every child should learn English”, the statement is specific enough? The answer is NO.

You can make it even more specific, which will make your logic more focused and convincing.

• What does ” Every child ” mean? Every child in Japan? or all children in general? or children who want to work globally in the future? Definition may make a big difference in your logic development.
• What is the situation of “local industry is active”? The size of the market is growing? Stable employment? Lots of innovations are generated? etc.
• “Improvemment of operation”? in terms of cost effectiveness, efficiency or something else?

There are many aspects you have to consider to make it more specific before starting to develop your logic. Otherwise you will never know what your logic answers to…..

This is just an entrance of my class and logic development.  Have fun!

## Launched “Data&Story” website in English

The new website in English has just been opened for English-speaking customers.

As I have some classes in English at Yokohama National University, I am always welcome clients who want “business data analysis(Excel-based)”, ” problem-solving” programs taken place in English.

You can try those programs either in Japan or any other countries.

http://data-story.net/english/

My programs are all practical based on my 20 year experience at Hitachi and Nissan.

My clients are large organization which have issues to develop basic business skills in new business development, marketing, sales, administration etc.

While they have huge data and systems, they really do not have human skills to manage those technologies/data. My programs will help you have practical skills to make the most of your business assets.

The human skills will change your organization to be even more competitive with data analysis and logical problem-solving skills.

For more detail, please visit the site and please feel free to ask any questions if any.
