Linear measure of books on shelves in my dwelling:
I have EIGHT cabinets full of books, some double-shelved, plus another four or five boxes of books (because I've run out of space on my cabinets.) Each cabinet has between four to six shelves. Each shelf is at least five feet long.
8 * 4 * 5 = 160 linear feet of books, minimum.
Software Quality In a Non-Software Company?
For over five years, I worked for an international biotech company that has been around for over 150 years. My title was "Senior X Engineer", where X varied from Software to Bioinformatics. I had specializations in genetics and statistics.
I have been where you are.
And I was not able to get my company to wake up, either.
You have already talked with the CEO. The CEO has listened, and he told you that he has bigger things to worry about.
That is the final answer. Things will not change at your company.
I strongly advise you: update your resume, and find another place that cares about quality. Because poor quality software will be discovered. The managers will actively seek someone to blame. And because you complained, those same managers are likely to blame you for the bad quality.
No, it's not fair. It happens anyway.
I'm serious: you are on a sinking ship, and you will be the first one blamed. Update your resume, find a new job while you're getting your current paycheck, and switch.
