Systems Dynamics is a methodology used to understand the behavior of complex systems over time. It focuses on the interactions and feedback loops within a system, allowing for the analysis of how different components influence one another. This approach is particularly useful in fields like economics, environmental science, and organizational management. By creating simulation models, practitioners can visualize potential outcomes and test various scenarios. This helps in identifying leverage points for effective intervention and decision-making. Overall, Systems Dynamics provides valuable insights into the dynamics of systems, enabling better planning and management.
