What is described here is for me a competent technical manager. As they scale, it is just that their focus cannot be on everything at the same time so they need to pick what is the most important and help a specific team at specific times. It also means that they need a good bullshit detector to dodge those that are skilled at "managing up" and know the real underlying state. Unfortunately the organizations tend to follow Peter's principle and you end up with incompetent managers everywhere that just "manage" and don't understand what is made or how.
