TRACEABILITY OF REQUIREMENTS IN SCRUM SOFTWARE DEVELOPMENT PROCESS

University essay from Mälardalens högskola/Akademin för innovation, design och teknik

Abstract:

Incomplete and incorrect requirements might lead to sub-optimal software products, which might not satisfy customers’ needs and expectations. Software verification and validation is one way to ensure that the software products meets the customers’ expectations while delivering the correct functionality. In this direction, the establishment and the maintenance of traceability links between requirements and test cases have been appointed as promising technique towards a more efficient software verification and validation. Through the last decades, several methodologies supporting traceability have been proposed, where most of them realize traceability by implicitly exploiting existing documents and relations. Nevertheless, parts of the industry is reluctant to implement traceability within software development processes due to the intrinsic overhead it brings. This is especially true for all those light-weight, code-centric software development processes, such as scrum, which focus on the coding activities, trying to minimizing the administrative overhead. In fact, the lack of documentation finishes to hamper the establishment of those trace links which are the means by which traceability is realized. In this thesis, we propose a methodology which integrates traceability within a scrum development process minimizing the development effort and administrative overhead. More precisely we i) investigate the state-of-the-art of traceability in a scrum development process, ii) propose a methodology for supporting traceability in scrum and iii) evaluate such a methodology upon an industrial case study provided by Westermo.
