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.

The system of transportation is not coherent; it is not treated as integral. Roads compete with with railroads and airlines in chaotic fashion, and at immense cost to the nation.

Management problems are not respecters of the company organization, nor of the talents of the people appointed to solve them.

A stochastic process is about the results of convolving probabilities-which is just what management is about, as well.

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.

It is the concept of likelihood that a real understanding of probability resides, and we must learn how to measure it.
