This paper introduces an executable system dynamics simulation model developed to help project managers comprehend the effects of requirements volatility. Requirements volatility and its effects were studied using various analysis and modeling techniques. The requirements volatility study results were used to design major simulator components that were integrated into a previously developed and validated simulator, leveraging pre-existing software risk related systems dynamics research. The base simulator was also extended to provide an encompassing view of the requirements engineering process. The distributions used for stochastically simulating the requirements volatility risk effects and requirements engineering factors were derived from a survey that included over 300 software project managers. The simulator can be used as an effective tool to demonstrate the researched effects of requirements volatility on a software development project.
