Many OSS projects are composed of a mix group of firm-paid and volunteer developers, with different motivations, collaboration practices and working styles. As OSS development consists of collaborative works in nature, it is important to know whether these differences have an impact on collaboration between difference types of stakeholders, which lead to an influence in the project outcomes. In this paper, we empirically investigate the firm-paid participation in resolving OSS evolution issues, the stakeholder collaboration and its impact on OSS issue resolution time. The results suggest that though a firm-paid assigned developer resolves much more issues than a volunteer developer does, there is no difference in issue resolution time between them. Besides, the more important factor that influences the issue resolution time comes from the collaboration among stakeholders rather than from individual characteristics.}, keywords = {COLLABORATION, companies, coordination, defects, feature requests, geronimo, jira, qpid, qt, social network analysis, volunteer}, author = {Duc, Ach Nguyen and Cruzes, Daniela S. and Ayala, Claudia and Conradi, Reidar} } @article {springerlink:10.1007/s10588-006-9006-3, title = {Correlating temporal communication patterns of the Eclipse open source community with performance and creativity}, journal = {Computational \& Mathematical Organization Theory}, volume = {13}, year = {2007}, note = {"Social network data was collected from the Eclipse component development groups{\textquoteright} online mailing lists by using the online process tool (Gloor and Zhao, 2004).

It measures the productivity of each community and seeks to identify correlations that exist between group communication characteristics and productivity attributes. The study uses the TeCFlow (Temporal Communication Flow) visualizer to create movie maps of the knowledge flow by analyzing the publicly accessible Eclipse developer mailing lists as an approximation of the social networks of developers and users. Thirty-three different Eclipse communities discussing development and use of components of Eclipse such as the Java Development Tools, the different platform components, the C/C++ Development Tools and the AspectJ extension have been analyzed over a period of six months. The temporal evolution of social network variables such as betweenness centrality, density, contribution index, and degree have been computed and plotted. Productivity of each development group is measured in terms of two indices, namely performance and creativity. Performance of a group is defined as the ratio of new bugs submitted compared with bugs fixed within the same period of time. Creativity is calculated as a function of new features proposed and implemented. Preliminary results indicate that there is a correlation between attributes of social networks such as density and betweenness centrality and group productivity measures in an open source development community. We also find a positive correlation between changes over time in betweenness centrality and creativity, and a negative correlation between changes in betweenness centrality and performance.}, keywords = {bug fixing, bugs, bugzilla, communication, creativity, developers, eclipse, email, email archives, feature requests, mailing lists, performance, productivity}, issn = {1381-298X}, url = {http://dx.doi.org/10.1007/s10588-006-9006-3}, attachments = {https://flosshub.org/sites/flosshub.org/files/16.pdf}, author = {Kidane, Yared and Gloor, Peter} } @article {flosswp113, title = {The Impact of Ideology on Effectiveness in Open Source Software Development Teams}, journal = {MIS Quarterly}, volume = {30}, number = {2}, year = {2006}, note = {"...we collected data related to OSS projects hosted on Sourceforge (www.sourceforge.net)."

This paper develops a framework of the OSS ideology (including specific norms, beliefs, and values) and a theoretical model to show how adherence to components of the ideology impact effectiveness in OSS teams. The model is based on the idea that ideology provides clan control, which is important in OSS development settings because OSS teams generally lack formal behavioral and outcome controls. The paper hypothesizes both direct effects of ideology on OSS team effectiveness and indirect effects via influences on affective trust, cognitive trust, and communication quality. Hypotheses are tested using survey and objective data on OSS projects. Four effectiveness measures are used to capture unique aspects of effectiveness in OSS including both the extent to which a team attracts input from the community and the team{\textquoteright}s success in accomplishing project outcomes. Results support the main thesis that OSS team members{\textquoteright} adherence to the tenets of the OSS community ideology enhances OSS team effectiveness.
