There is growing application of simulation to practical training in management of business on strategic and operational level. In use are simple models where a business is immersed in a much bigger market which sets the context, and others where the context is set dynamically by the actions of the competitors (3), (4).The simulation exercises reported are centered on the question of how to appreciate the impact of a reactive context in managing a business (1). The Implementation of Simulation with continuous simulation (Dynamo, etc.) gives easy appreciation of the impact of operational dynamics in a reactive strategic context.
