Prior research has shown that customer-reported software faults are often the result of violated dependencies that are not recognized by developers implementing software. Many types of dependencies and corresponding measures have been proposed to help address this problem. The objective of this research is to compare the relative performance of several of these dependency measures as they relate to customer-reported defects. Our analysis is based on data collected from two projects from two independent companies. Combined, our data set encompasses eight years of development activity involving 154 developers. The principal contribution of this study is the examination of the relative impact that syntactic, logical, and work dependencies have on the failure proneness of a software system. While all dependencies increase the fault proneness, the logical dependencies explained most of the variance in fault proneness, while workflow dependencies had more impact than syntactic dependencies. These results suggest that practices such as rearchitecting, guided by the network structure of logical dependencies, hold promise for reducing defects.

Open source software (OSS) communities live and die with the continuous contributions of programmers who often participate without direct remuneration. An intriguing question is whether such sustained participation in OSS projects yields economic benefits to the participants. Moreover, as participants engage in OSS projects, they take on different roles and activities in the community. This raises additional questions of whether different forms of participation in OSS communities are associated with different economic rewards and, if so, in which contexts. In this paper, we draw upon theories of signaling and job matching to hypothesize that participants who possess “proof” of their skills in OSS projects are financially rewarded for their activities in the labor market. More specifically, we distinguish between participation in OSS communities that is associated with a signaling value for unobserved productivity characteristics and an additional value that accrues to participants whose OSS roles and acti...
