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

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

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.

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

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

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

Instead of trying to specify a system in full detail, specify it only somewhat. You can then ride on the dynamics of the system in the direction you want to go.
