  Requirements are found to change in various ways during the course of a
project. This can affect the process in widely different manner and extent.
Here we present a case study where-in we investigate the impact of requirement
volatility pattern on project performance. The project setting described in the
case is emulated on a validated system dynamics model representing the
waterfall model. The findings indicate deviations in project outcome from the
estimated thereby corroborating to previous findings. The results reinforce the
applicability of system dynamics approach to analyze project performance under
requirement volatility, which is expected to speed up adoption of the same in
organizations and in the process contribute to more project successes.
