I got first job doing COBOL back in 1995. Second code change I did I got called into managers office.
He asked how I felt about change. I stated it was easy being only 2 line change to 1 module.
That change saves us 2 million ukp a year he says.
Ever since tried to write as little as possible . Amazing what you can do when you understand the problem , understand the code and find the one change that does it.
Not sure my method of wandering through code, chatting to everyone and then submitting a 4 line commit would fit with IBM
