In this article, we transform thoughts from classical strategy and insights from modern complexity science into a novel concept of intervention. In doing so, we pursue two goals: First, to improve the prediction of outcomes, and second, to refine the design of interventions. For the first purpose, we outline approaches to modeling the natural behavior of systems and the effect of interventions. For the second purpose, we propose an idea forthe design of interventions. We call the concepts that relate to modeling system behaviors system dynamics, and those that relate to predicting outcomes of interventions intervention dynamics, and we call the concepts that relate to the design of interventions intervention design.
