Abstract

We describe a hybrid computer simulation model of the software development process that is specifically architected to study alternative ways to configure global software development projects, including phased-based, module-based, and follow-the-sun allocation strategies. The model is a hybrid system dynamics and discrete event model. In this paper, test cases have been developed for each allocation strategy, and project duration under each configuration is computed under a range of plausible assumptions for key parameters. The primary finding is that although under ideal assumptions, follow-the-sun is able to produce impressive reductions in time-to-market, under more realistic assumptions the reverse is true, thus corroborating findings by other researchers. Further analysis reveals the presence of some interaction between the assumptions, but the results remain robust.
