This talk by Russ Ackoff provides you with an all embracing introduction to Systems Thinking and Complexity Adaptive Dynamics.

 

Understanding Systems 

Russ Ackoff most succinctly described what constitutes a system and its core characteristics as:

  • A system is a whole that is defined by its function(s) in one or more containing systems.
  • Every system contains at least two essential parts and these must satisfy three conditions.
    • Every essential part of a system can affect its behavior or properties.
    • The way an essential part affects the properties or behavior of the whole depends on the state or activity of at least one other part of the system.
    • Groups of essential parts, subsystems, also can affect the behavior and properties of the whole system and none has an independent effect on it.

 

Some important properties of a system derive from its definition.

  • When a system is taken apart it loses its essential properties.
  • No part of a system can carry out the function that defines the system.
  • When a system is taken apart its essential parts lose their ability to carry out the function they have in the whole.
  • When the performance of any essential part of a system, taken separately, is improved, the performance of the whole may not be.
