"Projects to be studied were selected from those hosted on SourceForge, (http://sourceforge.net/)"
"we chose projects for which data we need for our analysis are publicly available, meaning a large number of bug reports"
"we chose teams with more than 8 developers"
"Only 140 projects of SourceForge met the first two requirements in 2002 when we drew our sample"
kicq, gaim, phpmyadmin, dynapi
"First, we obtained data indica- tive of the effectiveness of each project, such as its level of activity, number of downloads and development status"
"we elected to use objective data about the bug- fixing process. Hence, the main source of data about the bug-fixing process was obtained from the archives of the bug tracking system, which is the tool used to support the bug-fixing process"
