While there are plenty of processes out there that likely don't need to be, there are I'd venture a lot more where the value generated isn't necessarily obvious to the guys in the trenches. I'm happy to explain this to anyone who asks (and have) and we occasionally even have an issue crop up where hey, look how useful this "busywork" you did earlier is right now, but the point is to a certain degree you should expect to simply obey the stated rules even if you don't IMMEDIATELY see their value. It's just respectful.
I'd also say it's far too easy to conflate "mindless obedience" and "respectful behavior" these days.
Maybe this should be a rule of thumb: Don't criticize anything during your first six months. If it's your first job out of school, don't criticize anything during your first year. Learn what's really going on, and why things are the way they are. Then you can criticize.
