"First, we chose projects for which data we need for our analysis are publicly available (not all projects allow public access to the bug tracking system). Second, we chose teams with more than 8 members...we tried to select more and less suc- cessful development teams. To this aim we used the definitions of success proposed by [9], who suggest that a project is successful if it is active, the resulting software is downloaded and used and the code matures"
"Kicq, Gaim and PhPmyAdmin were chosen" - effective
DynAPI was chosen as an example of a less effective project"
"We collected data indicative of the success of each project, such as its level of activity, number of downloads and development status. We then collected data from the archives of the bug tracking system, the tool used to support the bug fixing process"
