Resolution trend of just-in-time requirements in open source software development

Research in "just-in-time" requirements engineering has recently emerged. Some research has explored the nature of just-in-time requirements analysis in open source software (OSS) systems. Whereas, others have focused on techniques, such as traceability-enabled refactoring and horizontal traceability, in order to help manage just-in-time requirements. Little is known, however, about the resolution trends of just-in-time requirements in OSS development. In this position paper, we analyze the resolution time of the requirements of Firefox and Mylyn, and identify interesting patterns throughout their development history. Our analysis instigates five intriguing questions regarding the characteristics of just-in-time requirements engineering for OSS systems, and opens further research avenues in this area.
