In its simplest sense, systems thinking gives you a more accurate picture of reality, so that you can work with a system's natural forces in order to achieve the results you desire. Finally, systems thinking is founded on some basic, universal principles that you will begin to detect in all arenas of life once you learn to recognize them. A system is a group of interacting, interrelated, and interdependent components that form a complex and unified whole. Most systems thinkers focus their attention on living systems, especially human social systems. However, many systems thinkers are also interested in how human social systems affect the larger ecological systems in our planet.
Every system has a purpose within a larger system.
All of a system's parts must be present for the system to carry out its purpose optimally. If you removed any one of these components, this system could no longer function. A system's parts must be arranged in a specific way for the system to carry out its purpose. Systems change in response to feedback. The word feedback plays a central role in systems thinking.
