Essential Characteristics of the Systems Model

A system is a whole that cannot be divided into independent parts without losing its essential characteristics as a whole. It follows from this definition that, a system’s essential defining properties are the product of the interactions of its parts, not the actions of the parts considered separately. Therefore, when a system is taken apart, or its parts are considered independently of each other, the system loses its essential properties. Furthermore, when performance of each part taken separately is improved, the performance of the system as a whole may not be, and usually isn’t. --Russell Ackoff
