The successful operation of a designed system usually involves feedback.
The feedback of output from some parts of a system to input for other parts
can be used to encourage what is going on in a system, discourage it, or
reduce its discrepancy from some desired value. The stability of a system
can be greater when it includes appropriate feedback mechanisms.
