To determine how well the model fits reality, one determines how valid the model is for the current situation. This is somewhat different to the nature of simulation modelling in the military domain, another major application of simulation in operational research, where models tend to be of a much larger scale and where they are. The model itself is organized around the six primary management processes of Plan, Source, Make, Deliver, Return and Enable. We need to know where design fits into the whole research process from framing a question to finally analysing and reporting data. This change management model was created in the 1950s by psychologist Kurt Lewin. Static models are systems of equations that are solved once.
