Systems Models and Thinking

Overview


Systems thinking attempts to understand processes in terms of systems of interconnected pieces. The simplest version of systems models are the bathtub models.

Basic Setup


  • Elements - are the actors in the systems. Elements generally need to have a measurable aspect to them. The measures associated with elements are often referred to as stocks.
  • Relationships - are inter-connections between the elements. One element influences another through its relationship. The rate of change of one element is referred to as a flow.
  • Purpose or Function - what the system is trying to accomplish.
