[#1]

Mr. Katsushige Hamaguchi

Murata Manufacturing Co., Ltd.

JMP User history:

1999 Five From around the month

My surprising side:

It's a shy place. It may seem scary at first impression because he is shy, but in reality it is not so, and he has a mild and sociable personality.

I like hot springs and saunas, so I went to the area around Tokyo quite a bit. I used to use "Ofuro no Osama" in Oimachi near Haneda Airport and Tokyo Station. ® "is. There are various baths and the sauna is large. We also recommend "Hisamatsuyu" in Nerima Ward, "Kuranoyu" in Higashimatsuyama, and "Shimizuyu" in Musashikoyama. Outside of Tokyo, "Ranpu no Yu" in front of Izumo City Station is also good. Although it is small, the quality of the spring is very good.

1. JMP What is your favorite feature of?

It is a link function between data and graph. Click on the part of the graph that interests you to highlight the graph and data.

2. What was your first job?

University 1 I worked at a consumer electronics retail store during the summer vacation of the year. When I wanted to get a job related to electrical machinery in the future, I was recruited for a part-time job at the university. Sony's "Walkman" was the first product sold in charge of the audio-related floor. ® I remember it was. While working, I realized that the other person wouldn't be interested in anything unless I was serious about it. When I seriously said, "I feel this product like this, so I think it's good," I remember being told by customers to buy it.

3. What made you interested in statistics?

"Quality Control Seminar Basic Course" sponsored by the Union of Japanese Scientists and Engineers 6 I took the seminar for a month. Before that, I had some understanding of mathematical formulas and calculations, but even if I knew it as a mathematical formula, I did not fully understand what it meant and how it was used in my work. In the process of learning from the basics in this seminar, my understanding of statistics deepened and my interest naturally increased. At the same time, in-house JMP I was even more interested in introducing.

4. When did you first do your statistical work?

In 1997, we started to revise our own statistical analysis software. At that time MS-DOS from Windows® At the time of transition to MS-DOS What was made in the base Windows® We ported it to the base and supported internal users.

5. What was your most proud moment as a professional?

After attending the in-house training, you may be asked "How should I analyze this data?" At such times, I was very happy to realize that "I learned statistics and data analysis and became interested in it."

Recently, I have been consulted for data analysis as an in-house business support. I analyze it together while listening to the explanation from the counselor, but when I check it using the link function of the graph, I noticed a change at a certain point and said, "Did you maintain the equipment at this time?" I was happy to see that the cause was exactly that, and the consultant was very surprised to find out by data analysis.

6. Which part of your work do you like?

Now I am an instructor for in-house training. When providing on-site support, some employees are interested in using what I have taught before, such as design of experiments, even after their work has changed. JMP I'm doing data analysis at. " It's still rewarding to get such a reaction at work.

7. Recently JMP How are you using?

SQC ( Statistical Quality Control , Statistical quality control) education and follow-up of in-house engineers. actually JMP We provide practical guidance on how to utilize this in your work.

8.JMP What was your first project with?

In-house software that was used in the past is made by another company ( JMP ) Was a switching project. We are starting to store manufacturing process data in a database, and our software was not powerful enough to analyze that data. JMP "Exploratory data analysis" turned out to be very effective, JMP Will be introduced. Japanese version at that time JMP It was before the release of, so the English version JMP and JMP For internal use while having the support staff teach JMP I created an operation manual.

9. JMP Developers and John Sall Is there anything you would like to tell us?

In the "Decisive Screening Plan" 6 Is it a cause? 7 At least if it is a cause 20 The number of experiments is required, but from the standpoint of actual development, it will not be easy to handle that number. I would like to have a function that can produce results with a small number of experiments and a function that plans the optimum experiment from the various data and knowledge that I have now.

10. How do you think the fields of data science and analytics will change in the future?

With the progress of AI, the "data analysis" that is being performed now will be in the future AI Will do it all. In that case, the comprehensive and creative field becomes "human work".

The creative area of our manufacturers is "research and development." I think it will be important from now on how to utilize statistics in that work. In other words, I wonder if I will eventually become a job as a data scientist.

Analyzing with a large amount of data is no longer a "human job", and it is a game of how to produce results with a small amount of data, so it is necessary for humans to think properly. is. JMP I hope that it will continue to be software that assists such places.
