RESUMO:

The delivery of addressed software issues (i.e., bug fixes, enhancements, and new features) is what drives software development. Previous research has investigated what impacts the time to triage and address (or fix) issues. Nevertheless, even though an issue is addressed, i.e., a solution is provided and tested, such an issue may still suffer delay before being delivered to end users. Such delays are frustrating, since end users care most about when an addressed issue is available in the software system (i.e, released). In this matter, there is a lack of empirical studies that investigate why addressed issues take longer to be delivered compared to other issues. In this thesis, we perform empirical studies to understand which factors have strong association with the delay to deliver addressed issues. In our studies, we find that 34% to 98% of the addressed issues of the ArgoUML, Eclipse and Firefox systems have their integration delayed by at least one release. Our explanatory models achieve ROC areas above 0.74 when explaining delivery delay. We also find that the workload of integrators and the moment when an issue is addressed are the factors with the strongest association with delivery delay. We also investigate the impact of rapid release cycles on the delay to deliver addressed issues. Interestingly, we find that rapid release cycles of Firefox are not related to faster delivery of addressed issues. Indeed, although rapid release cycles address issues faster than traditional ones, they take longer to deliver such addressed issues. Moreover, we find that rapid releases deliver addressed issues more consistently than traditional ones.
