Agree. I have repeatedly said one mangement fundamental is control is commensurate to accountability. Thereafter, what you write deals with increasing control or decreasing depending on outcomes.

I also agree with point about canning or demoting senior staff. My better half had to deal with a complete jerk senior manager. It took an act of God to make the organization hold that clown accountable. In the end his team was downsized, but I'm not sure if he ever lost his title. Why? Senior managers + HR are serious believers in the unitary theory of the executive. As I say it takes an act of God to make them see what they did is not right by definition.
