WHAT IS SYSTEM?

Everybody is familiar with the word system and uses it in everyday language. We speak of heating systems, communication systems, economic systems, and transportation systems. We talk of cultural and social systems. The word system is used because it conveys the idea that these things are made up of parts and that the parts somehow interact with each other for some purpose or reason. A system is an organized or complex whole – an assemblage or combination of things or parts performing as a complex or unitary whole.

This definition implies several ideas. First is the concept of interdependency. If a change occurs in one part or set of parts, it affects all other parts of the system. This affect on each part may be direct or indirect.

A second implication of the definition of a system is the concept of wholism. This means that the system should be considered as a functioning whole. Changes in parts of the system and in the functioning of elements of the system should be considered from the standpoint of the system’s overall performance.

A third concept implied by the definition is synergism. This refers to the interactive effect of the parts of the system working together. The actual interaction of the parts creates an effect which is greater than the effect of the parts acting separately.
