Its been years since I attended the MIT Executive Course on System Dynamics taught by John Sterman. Even so it made a lasting impression on me. Based on the works of Jay Forrester and Peter Senge I learned the principles of system dynamics and how to develop models and simulators. While commercial modeling software exists it is a bit expensive.
Enter Insight Maker provided by Gene Bellinger of Systems Thinking World – it’s a free and open source tool for creating such models and simulations. I encourage you to check it out.
