Steve Jobs famously said, "I don't hire smart people to tell them what to do. I hire them to tell me what to do". He didn't always live up to that but his point was valid.
Management is all about choices with limited information - there is rarely one clear and obvious route forward, but a strategy of following all routes simultaneously will lead to failure as there needs to be focus.
So somebody has to make that choice and then drive that focus through the organisation.
This can be very difficult when the choice isn't clear and obvious - as lots of smart people will have different views.
That's the art of management - you need to make the right choices most of the time. and when you've made the wrong one correct quickly, but you also need to be able to get the organisation to rally behind that choice, even if not everyone agrees.
I think org charts would better fit how I think of the organizations they represent if they were drawn upside-down, like a tree.
I think this is often wrong for two reasons
- the layers are not entirely disconnected - the devil is often in the details
- hard to detect BS from subordinates
