When organisations are formed of people with perfectly aligned incentives, they don't need to be managed. Such people know what needs to be done and have the expertise and autonomy to make it happen.
Of course, such an organisation is hopelessly unlikely to retain this utopian state as the number of employees rises above 2. And it becomes vanishingly improbable if outside funding is involved.
So management is the act of taking care of something which can't take care of itself. A symptom: like an antibody, it arises when a system gets of out whack and its continued presence indicates a chronic condition.
The best thing management can do is to put systems in place to make itself redundant. So, by this definition, anything it does which promotes the opposite goal is a mistake.
