Process works though, because not everyone on your team is going to be an "A" student, and if you have 500 employees, you simply don't have the time and bandwidth to make a custom process for each person. There's wide ranges of ability at every company, even prestigious FAANGs and investment banks and pretty much everywhere. The great benefit of layering on heavy process and bureaucracy is that you can get homogenized, reliable, reasonable-quality, but not consistently outstanding, output from the A, B, C, and D players, without terrible risk that someone who doesn't know what they are doing (who every company has) fucks everything up. As the saying goes, every process you encounter is scar tissue from a past fuck-up. What you sacrifice with all this bureaucracy is the absolutely brilliant output you could be getting from the A players, but the cost is usually worth mitigating the risk of disaster.
