It's lived experience. My management is a lot happier when I move too fast to really pay attention to the problems and use my expertise, and the output is good enough that nobody really complains. Building most software is no longer skilled work; it takes minimal training. The industry just hasn't caught up yet.
Well. I own my business and I really hate this attitude that some startups executives have. I want quality. Not blind speed. I want speed to be a by product of a well built product and a system that builds it. Not a bunch of slop thrown over the wall that I have to then debug and fix.
