This problem is pretty much every company I've ever worked for if/when they got over six engineers. I spend more time and a hell of a lot more energy than I should trying to keep managers or easily enthused engineers from hugging the project to death.
I ended up becoming a process expert out of a sense of self preservation. I use process a lot, but it's always in support of the 'why's. I don't always talk about the 5 Whys but it's always there, and in my experience the people who are usually the problem can't ever manage more than three.
The worst of these are also the sort of people who, if your speedometer was broken, would insist that the car is not moving. Even after you told them to look out the window.
