Global and Geographically Distributed Work Teams: Understanding the Bug Fixing Process and Potentially Bug-prone Activity Patterns

Abstract of talk. The main goal of this research is focused on the better understanding of the bug life cycle and potential human related factors that may be more prone to be buggy than others. This study is done thanks to the existence of publicly available data sources that help to retrieve the point in time when an issue has been fixed in the source code, but also to trace, through the study of the history stored in the versioning system, when that issue was introduced, by whom and what was modified. This will help to better understand how issues are being introduced in the source code and improved the knowledge over the bug life cycle. In addition, it is possible to undertake specific studies related to typical patterns of activity that may be more prone to be buggy than others. This study has focused on two of them: experience and the time of the day.
