THE RELATIONSHIP AMONG DEVELOPMENT SKILLS, DESIGN QUALITY, AND CENTRALITY IN OPEN SOURCE PROJECTS
In a previous paper, we have found empirical evidence supporting a positive relationship between network
centrality and success. However, we have also found that more successful projects have a lower technical
quality. A first, straightforward argument explaining previous findings is that more central contributors are
also highly skilled developers who are well known for their ability to manage the complexity of code with a
lower attention to the software structure. The consolidated metrics of software quality used by the authors in
their previous research represent measures of code structure. This paper provides empirical evidence
supporting the idea that the negative impact of success on quality is caused by the careless behaviour of
skilled developers, who are also hubs within the social network. Research hypotheses are tested on a sample
of 56 OS applications from the SourceForge.net repository, with a total of 378 developers. The sample
includes some of the most successful and large OS projects, as well as a cross-section of less famous active
projects evenly distributed among SourceForge.net’s project categories.
