Abstract
Open source developers, particularly the elite developers who own the administrative privileges for a project, maintain a diverse portfolio of contributing activities. They not only commit source code but also exert significant efforts on other communicative, organizational, and supportive activities. However, almost all prior research focuses on specific activities and fails to analyze elite developers’ activities in a comprehensive way. To bridge this gap, we conduct an empirical study with fine-grained event data from 20 large open source projects hosted on GITHUB. We investigate elite developers’ contributing activities and their impacts on project outcomes. Our analyses reveal three key findings: (1) elite developers participate in a variety of activities, of which technical contributions (e.g., coding) only account for a small proportion; (2) as the project grows, elite developers tend to put more effort into supportive and communicative activities and less effort into coding; and (3) elite developers’ efforts in nontechnical activities are negatively correlated with the project’s outcomes in terms of productivity and quality in general, except for a positive correlation with the bug fix rate (a quality indicator). These results provide an integrated view of elite developers’ activities and can inform an individual’s decision making about effort allocation, which could lead to improved project outcomes. The results also provide implications for supporting these elite developers.

- Unveiling Elite Developers’ Activities in Open Source Projects
Recommendations
Elite developers' activities at open source ecosystem level
ICSE '20: Proceedings of the ACM/IEEE 42nd International Conference on Software Engineering: Companion ProceedingsOSS ecosystems promote code reuse, and knowledge sharing across projects within them. An ecosystem's developers often develop similar activity patterns which might impact project outcomes in an ecosystem-specific way. Since elite developers play ...
Assisting the elite-driven open source development through activity data
ESEC/FSE 2020: Proceedings of the 28th ACM Joint Meeting on European Software Engineering Conference and Symposium on the Foundations of Software EngineeringElite developers, who own the administrative privileges for a project, maintain a diverse profile of contributing activities, and drive the development of open source software (OSS). To advance our understanding and further support the OSS community, I ...
Assessing the efficacy of user and developer activities in facilitating the development of OSS projects
Although the development of open source software (OSS) projects is known to be critically dependent on many key factors, the precise contribution of the various user and developer activities toward the development of an OSS project is unknown. Therefore,...
