Abstract
The invisibility of the individuals and groups that gave rise to requirements artifacts hasbeen identified as a primary reason for the persistence of requirements traceabilityproblems. This paper presents an approach, based on modelling the dynamic contributionstructures underlying requirements artifacts, which addresses this issue. We show howthese structures can be defined, using information about the agents who have contributedto artifact production, in conjunction with details of the numerous traceability relationsthat hold within and between artifacts themselves. We describe a scheme, derived fromwork in sociolinguistics, which can be used to indicate the capacities in which agentscontribute. We then show how this information can be used to infer details about thesocial roles and commitments of agents with respect to their various contributions and toeach other. We further propose a categorisation for artifact-based traceability relationsand illustrate how they impinge on the identification and definition of these structures.Finally, we outline how this approach can be implemented and supported by tools,explain the means by which requirements change can be accommodated in thecorresponding contribution structures, and demonstrate the potential it provides for"personnel-based" requirements traceability.
