When I worked at Chrysler there was a large churn of process engineers. Each successive engineer would come up with some grand idea of how to improve a job/group of jobs on the assembly line.

It didn't matter how logical that "lowly" line guy's (who had been installing said part 800 times per day for twenty years making him the worlds foremost expert on installing said part) argument against was. or how many previous engineers had the same "original" concept, forced implementation of it, wasted time and money.

No, the engineers idea was somehow magically better.

I never met a process engineer there that could accept the fact that their idea was not novel.
