Using system dynamics modeling to manage projects

The paper focuses on improving the planning and tracking abilities of software projects through the utilization of system dynamics modeling. A prototyped software project management tool, which incorporates a system dynamics model of the concurrent incremental development process, was developed and is described. The tool enables project personnel to plan and track a project in terms of schedule, budget, and quality. It also provides a “what if” capability that enables project personnel to assess the impact of proposed project control actions in terms of schedule, budget, and rework hours. These proposed actions are analyzed, utilizing the underlying system dynamics model which evaluates the actions in terms of dependencies and feedback loops among project variables. The concepts discussed in the paper and demonstrated through the prototype tool should be integrated into existing project management tools to increase their power and effectiveness
