This highly-paid factory efficiency expert was enthusiastically explaining how he works. "You just listen to the workers. They know where the inefficiencies are"
I've worked with senior managers who have zero regard for the knowledge of the people doing the work. It might be those workers don't have some over-arching conceptual framework for how the company works, but they do have intimate and sometimes deep knowledge of what they do all day. And not taking advantage of that is a huge blind spot.
