Abstract-Simulations are today very common and are used frequently for education, testing, research, development, gaming etc. With a simulation and a decision support system, certain factors are manipulated depending on what event is being emulated. This report is about how to proceed to develop an environment with the basis of an expert system, which helps project managers to develop a software project. By developing a simulation model, based on a specific software development model, that model could be implemented in a project game, this to give the player the possibility to control and steer certain events in the project and to vary the result of the game.
