Abstract Details

2019, MS, University of Cincinnati, Engineering and Applied Science: Computer Science.
To understand requirements traceability in practice, we present a preliminary study of identifying questions from requirements repositories and examining their answering status. Investigating 345 open-source projects results in 20,622 requirements questions, among which 53% were answered successfully, 15% were answered unsuccessfully, and 32% were not answered at all. To be able to answer the requirements traceability questions effectively, the developers need traceability links. we found that the trace links can differ based on the usage of those links for various tasks. We present this via an empirical study where we explicitly assign the participants into 3 trace-usage groups of one requirement: ?nding its implementation for verification and validation purpose, changing it within the original software system, and reusing it toward another application. The results uncover what we call “gray links”—around 20% of the total traces are voted to be true links with respect to only one task but not the others. We provide a mechanism to identify such gray links and discuss how they can be leveraged to advance the research and practice of value-based requirements traceability. For traceability in practice, developers need to consider the usage if requirements traceability questions to provide a successful answer.
