Process is about HOW you do things.
Product is about WHAT you make.
I do think that both are necessary but taken to the extreme as you see in Japan and US doesn’t lead to any easy reconciliation.
It was pretty much impossible to get these (highly accomplished and talented) engineers to accept that their way (hardware and some firmware) would not work on software.
It usually ended up with them, labeling my efforts to introduce flexibility as some variant of “lazy, bad-quality engineering.” Hard sell.
