Contribution structures offer a way to model the network of people who have participated in the requirements engineering process. They further provide the opportunity to extend conventional forms of artifact-based requirements traceability with the traceability of contributing personnel. In this paper, we describe a case study that investigated the(More)
The invisibility of the individuals and groups that gave rise to requirements artifacts has been identified as a primary reason for the persistence of requirements traceability problems. This paper presents an approach, based on modelling the dynamic contribution structures underlying requirements artifacts, which addresses this issue. We show how these(More)
Software traceability is a sought-after, yet often elusive quality in software-intensive systems. Required in safety-critical systems by many certifying bodies, such as the USA Federal Aviation Authority, software traceability is an essential element of the software development process. In practice, traceability is often conducted in an ad-hoc,(More)
For anything but the simplest of software systems, the ease and costs associated with change management can become critical to the success of a project. Establishing traceability initially can demand questionable effort, but sustaining this traceability as changes occur can be a neglected matter altogether. Without conscious effort, traceability relations(More)
It is widely assumed that following a process is a good thing if you want to achieve and exploit the benefits of traceability on a software development project. A core component of any such process is the definition and use of a traceability information model. Such models provide guidance as to those software development artifacts to collect and those(More)
Requirements engineering visualization is a rapidly growing field of research; however, the specific characteristics of what makes for effective visualizations during a particular engineering phase have not yet been distinguished. Visualizations, when coupled with traditional practices, augment the ability of resulting requirements artifacts to reach a wide(More)
The challenges of implementing successful and cost-effective traceability have created a compelling research agenda that has addressed a broad range of traceability related issues, ranging from qualitative studies of traceability users in industry to very technical and quantitative studies. Unfortunately, advances are hampered by the significant time and(More)
This paper describes lessons from running software development projects across three globally distributed educational institutions. What was innovative about this study was that two of the institutions were located in service providing countries, conventional on-shore/offshore roles were reversed, and students were exposed to the realities of global supply(More)
Traceability is demanded within mature development processes and offers a wide range of advantages. Nevertheless, there are deterrents to establishing traceability: it can be painstaking to achieve initially and then subject to almost instantaneous decay. To be effective, this is clearly an investment that should be retained. We therefore focus on reducing(More)
