It is terribly important to appreciate that some things remain obscure to the bitter end.

Policy-making, decision-taking, and control: These are the three functions of management that have intellectual content.

A slowly moving queue does not move uniformly. Rather, waves of motion pass down the queue. The frequency and amplitude of these waves is inversely related to the speed at which the queue is served.

The strategies that managers employ are at least as important as the facilities at their disposal.

There is, then, a logical priority about the arrangements, and logic has nothing to do with time.

According to the science of cybernetics, which deals with the topic of control in every kind of system (mechanical, electronic, biological, human, economic, and so on), there is a natural law that governs the capacity of a control system to work. It says that the control must be capable of generating as much "variety" as the situation to be controlled.

If cybernetics is the science of control, management is the profession of control.
