Russell L. Ackoff: System (page 2)

“Systems science and technology constitute one aspect of systems thinking, but the humanities and arts make up the other. The fact that design plays such a large part in the systemic treatment of problems makes it apparent that art has a major role in it as well. Ethics and aesthetics are integral aspects of evaluating systems… the systems approach involves the pursuit of truth (science) and its effective use (technology), plenty (economics), the good (ethics and morality), and beauty and fun (aesthetics). To compare systems methodology with that of any of the so-called ‘hard’ disciplines—for example, physics—is to misunderstand the nature of systems. The worry is not that the systems approach is not scientific in the sense which physics or chemistry or biology is, but that some try to make it scientific in that sense. To the extent they succeed, they destroy it.”

“Because the Systems Age is teleologically oriented, it is preoccupied with systems that are goal-seeking or purposeful, that is, systems that can display choice of either means or ends, or both. It is interested in purely mechanical systems only.”

Age

“Analysis of a system reveals its structure and how it works. It provides the knowledge required to make it work efficiently and to repair it when it stops working. Its product is know-how, knowledge, not understanding. To enable a system to perform effectively we must understand it—we must be able to explain its behavior—and this requires being aware of its functions in the larger systems of which it is a part.”

“A system is more than the sum of its parts; it is an indivisible whole.”

Russell L. Ackoff

It loses its essential properties when it is taken apart. The elements of a system may themselves be systems, and every system may be part of a larger system.
