Welcome!

We are a global association of ~1400 grappling with how to effectively create change in an increasingly complex world. Our emphasis is on the application of a systems thinking approach and the rigor of System Dynamics computer simulation to make progress on diverse challenges. Don’t be like Bob pushing the domino, join us as we build our capacity to change the world, together.
