I think you need to read between the lines to get what the Engineering Community is saying. When you try to micromanage something without any domain knowledge, you are doomed to scorn and in the long-term, failure. You do not follow a process blindly but understand the domain, your people and business objectives to adapt the process to a particular context. That is where the Software Management community has failed. A process which makes perfect sense in a Consulting context is forcibly thrust upon Product Development teams to everybody's detriment. And they can't see it!
