Evaluating process quality in GNOME based on change request data

The lifecycle of defects reports and enhancement requests collected in the Bugzilla database of the GNOME project provides valuable information on the evolution of the change request process and for the assessment of process quality in the GNOME sub projects. We present a quality model for the analysis of quality characteristics that is based on evaluating metrics on the Bugzilla database, and illustrate it with a comparative evaluation for 25 of the largest products within GNOME.
