The System Dynamics Approach
System Dynamics is a computer-aided approach for strategy and policy design.
The main goal is to help people make better decisions when confronted with complex, dynamic systems. The approach provides methods and tools to model and analyze dynamic systems. Model results can be used to communicate essential findings to help everyone understand the system’s behavior.
It uses simulation modeling based on feedback systems theory that complements systems thinking approaches. It applies to dynamic problems arising in complex social, managerial, economic, or ecological systems. System Dynamics can be applied to social, managerial, economic, ecological, and physiological systems.
Recognizing cause and effect in a system
From cause and effect to behavior
Levels and Rates
Building blocks for change over time
Modeling and Simulation
Using computation to show outcomes
Making better decisions based on analysis and understanding
The basic idea behind System Dynamics is that feedback loops capture the interactions between the system parts and how they lead to a certain overall pattern of behavior over time
System Dynamics is a branch of systems theory that includes model simulations to understand the dynamic behavior of complex systems as they change over time
Diagrams of the primary feedback loops in the system are often converted into computer simulations to model how changes in one part of the system may affect others and the overall pattern of development

Freely available policy simulation model. It gives everyone the chance to design their own scenarios to limit future global warming.
From Systems Thinking to System Dynamics
Systems thinking is a way to describe and understand the causality and interrelations between variables within a system. System Dynamics quantifies the impact of those interactions.
Systems thinking is a causality-driven, holistic approach to describing the interactive relationships between components inside a system as well as influences from outside the system. Its background emerges from various fields including philosophy, sociology, organizational theory, and feedback thought.
System Dynamics complements systems thinking by quantifying interactions and develops a time-dependent view of how the system behaves. The approach focuses on building computer models that represent and simulate complex problems in which behavior changes. These models bring to light less visible relationships, dynamic complexity, delays, and unintended consequences of interactions.
