I entered the electronics department of Isogo Technical High School because I wanted to study computers.
The reason I chose it was because I was in the training of making my own computer and it was the technical high school closest to my home.
The actual training began with the creation of the circuit board.
What I want to say is that programmer SE is a fight against loneliness.
Although the occupation is different, when I was in the first oval, Mr. Yuji Itoigawa, the general manager of the management department, often
Managers can complain about being lonely.
My impression was quite meticulous and delicate. Cleaning and tidying up was a big concern.
He has a rough personality and is the exact opposite of himself, who likes puzzles and Go.
For some reason, Mr. Yasuo Masuzawa, the manager of the information processing section, who reports directly to me, tells me about the current cost accounting and problems at the site.
Ask yourself. It's been three years since I joined the company, but ...
From now on, the chief of the information processing section is popular in the field, and about the manufacturing process and production control.
He had excellent knowledge, but lacked knowledge of accounting work.
Inside Oval, the management department, manufacturing department, and sales department were not very close to each other.
This may be good or bad because I was enrolled in the information processing section of the management department.
Itoigawa often said that the management department would be hated by both the manufacturing department and the sales department.
The view is that if you don't do that, you'll end up with a company of good friends.
Under such circumstances, Fujitsu decided to start an in-house system.
I also had the opportunity to talk to Fujitsu people, and I was clearly told that my thoughts (Hideki Kaneko) were old.
With this, the information processing section is not useful, and there were other reasons, but that is probably the number one cause.
The relocation destination was the sales window of the factory, but overtime work increased due to complaints and paperwork from sales.
I retired because I was about to break my body.
As I heard after retirement, Fujitsu and Oval seem to have developed to the point of trial.
Since then, when I say Fujitsu, I hate it.
Another impression I had was when I went through the banking system.
Mr. Tadataka Murao, General Manager of NEC's Finance Department.
I still think that there is a place that values etiquette when it comes to financial matters.
I retired from NEC and learned independently, I like baseball, I hate small things
He seemed to be in business.
The atmosphere in the workplace was quite violent and always yelled at me.
There is a reason to be convinced. Development has been prolonged for nearly a year.
Computer system development is a task that cannot be done without business knowledge and computer knowledge.
This business knowledge is accounting, tax, and banking knowledge.
.
If you study business knowledge to some extent, there are places where it is okay, but computer knowledge is
It is advancing day by day.
Therefore, it was designed by his boss who was working on a general-purpose machine such as old COBOL.
Computer systems had an old idea, a slow design.
I think.
I think so because I am in charge of the data migration team.
I think it was a department that I could understand.
If you're a programmer, just do one thing and do what you're told! !!
The main task of the data migration team is to check for inconsistencies and summarize the requests of banks, which are direct customers.
Therefore, everything that does not suit the customer is fixed.
The hardest part was the reliability of the data.
With the new system, the bank side has raised what the intermediate files are like.
The program for it was to be done by myself without a design document.
Therefore, I had no choice but to ask the person in charge of business directly. It takes an unusual amount of time.
I could understand the flow and the regular period to some extent, but I couldn't understand the loan, exchange, self-sufficiency, and foreign affairs.
It may be because there are some materials for current and regular loans, but there are few materials for loans, foreign exchange, self-sufficiency, and foreign countries.
Eventually, the comprehensiveness check totals table program made several modifications to speed up the process,
The relayed log file, which is an intermediate file, is incomplete until all logs can be confirmed.
The reason was that the specifications were not clear, and even if it was understood, it was done manually, and the data migration team was disbanded.
After a few years, "BankingWeb21" (BankingWeb21, BW21) was published on Wikipedia online.
"We have invested more than 20 billion yen in four countries: Japan, China, the United States, and India.
Developed but a blunder of the century "
Was written.
That should be the reason why only Yachiyo Bank and Mie Bank were adopted and as a package in advance
The program I made was forced to undergo a major remodeling at Yachiyo Bank.
It looked like a poor quality tool and system for banks
I think.
From now on, I think computer systems are a mass of ideas.
If the ideas do not match, the customer will dislike it and it will not work well.
I also think that equal communication is bad because the ideas do not fit.
There is also an idea that this is considered to be poor communication between groups.
