Not every big company is bad at this. I used to work for a large company in the aerospace sector (not an aircraft maker) where software was a big part of what they did. I was in the safety assurance part of the company, and on a couple of occasions I had to tell management that the software wasn't up to scratch. One of them was The Big Project On Which Everything Depends. Management didn't even blink. They went straight back to the supplier and spent the next several weeks in tough negotiations about timescale and how the additional costs were going to be split. The project was delayed, and I got zero blowback. They didn't even argue with me. The nearest I got to argument was some careful review of my report, which was perfectly reasonable given the amount of money at stake. I'm posting anonymously here and not naming names because I stand by my duty of confidentiality. But I am proud to have worked there.
