The use of conceptual system models and other tools to improve the understanding of how the feedback, delays and decision‐making policies in a system's structure generate the system's behavior over time. Systems thinking does not use computer simulation. Systems thinking involves (i) seeing interrelationships and feedback loops instead of linear cause–effect chains, and (ii) seeking processes of change over time rather than events/snapshots. Systems thinking helps people see things on three levels events, patterns of behavior and system structure.
