Emerging business models, value configurations, and information technologies interact over time to create competitive advantage. Modern information technology has to be studied, understood, and applied along the time dimension of months and years, where changes are the rule. Such changes created by interactions between business elements and resources are very well suited for system dynamics modeling. System dynamics models represent a frame-work for understanding both successful and unsuccessful IT management over time. Systems dynamics simulations provide insights into the important interactions between IT investments and firm performance over time.
