Management and technical skillsets are totally different, and in my experience, people who are good at politicking but not great at technical work move up, whereas great technical people tend to not be great at politicking and top out in engineering. The problem is there is often a lot of ego and imposter syndrome to those that move from technical to management, so they like to assert technical decrees or make decisions without trusting or consulting their SME’s. That’s the constant rub I have seen in several orgs now between management and the IT staff.
