The ability to acquire knowledge is an important determinant of performance for organizations. Developers and users can contribute knowledge to multiple OSS projects, and thereby create links between them through which knowledge can flow and facilitate performance. The contributions a project receives will affect its performance differently depending on the role of the participant and their relationship to other projects. The ability of projects to implement knowledge contributions into code will depend on the level of competition in the knowledge niche in which they exist. We examine how project performance is affected by user- and developer networks, and propose hypotheses relating network density, diversity, and competition to a project’s knowledge contributions and implementation.
