Community source has emerged as a unique way of developing enterprise software systems that require significant investments from partnering organizations. This new way of software engineering raises new questions on the issue of successful project development, which are significantly different from previous studies. The objective of this study is to develop a model for assessing project success under community source development. In this paper, we present a case of community source project called Kuali to understand the research questions, propose a unique research model for a survey study, outline the related hypotheses, and discuss our data collection methodology. We believe that our study is unique and will have significant impact on the successful introduction of the community source approach to enterprise application development.
