Software crowdsourcing for developing Software-as-a-Service

Recently software crowdsourcing has become a viable development paradigm for Software-as-a-Service (SaaS) ecosystems. TopCoder, one of the largest competitive programming communities, enables enterprises to tap into its global talent pool and crowdsource a variety of SaaS development tasks including requirement analysis, architecture design, code, and testing. Many researchers have proposed auction-based modelling methods to characterize general software crowdsourcing. But there are few papers on the comprehensive analysis of SaaS crowdsourcing process and developer community.This paper introduces a holistic analysis framework to model the SaaS-oriented software crowdsourcing from two dimensions: individual behavior in crowdsourcing contests and collective competition in the community. The framework includes a game-theoretical model to describe the competitive nature of software crowdsourcing process. Moreover, the framework defines a competition network to characterize the topological properties of a crowdsourcing community for SaaS development. The analysis of this model indicates that the success of a competitive software crowdsourcing project essentially depends upon the networks of key participants with sufficient skills and dedication for the project. This is validated by a large historical data collected from the Top-Coder website over a ten-year period.
