Modelling the contribution structure underlying requirements

Abstract

Improvements in requirements traceability (RT) are essential for developing better quality software
\nsystems. Based upon empirical investigations with practitioners, and an extensive survey of techniques and
\ntool support for requirements engineering (RE), we explain why conventional RT can only support limited
\nimprovements in quality, and suggest extensions required to provide further improvements. These
\nextensions revolve around the ability to continuously model, and hence trace, those who have contributed
\nin the production and refinement of the requirements specification (RS). In this paper, we propose an
\napproach to support such modelling, outline preliminary details, and discuss how it provides the
\nfoundations for developing quality software.
