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.

This thesis deals with project management and with different ways in which can be cur-rently approached. Beside the conventional, classical approach based on processes, modern approaches based on the theory of constraints and agile principles are discussed. Based on analysis, the main objective of the thesis is firstly to find weaknesses in the classical project management and strong key elements of modern approaches and after that to make suggestions to enhance the classical approach with the selected strong elements of modern approaches.

Syften med denna uppsats är att kartlägga hur utvecklare upplever platsoberoende scrum-utveckling, vilken problematik som uppstår samt om effektiviteten påverkas. För att uppnå studiens syfte och besvara de frågeställningar som formulerats i rapporten har data samlats in. Denna data har dels varit kvantitativ, där data har samlats in från en verksamhet som bedriver systemutveckling med metodiken scrum. Data har även varit kvalitativ där data i form av intervjuer har samlats in. Den insamlade datan har sedan analyserats för att kunna svara på forskningsfrågorna.   Efter genomförd analys har slutsatser dragits för att kunna uppfylla uppsatsen ursprungliga syfte. Den insamlade empirin tyder på att det finns viss problematik relaterad till kommunikation som blir tydlig när arbetet bedrivs platsoberoende. Den insamlade datan tyder även på en försämrad upplevelse av den sociala miljön när arbetet bedrivs platsoberoende. Slutligen tyder även det analyserade resultatet på en minskad effektivitet när arbetet övergått till platsoberoende. Det teoretiska ramverket ligger som grund för att redogöra för befintliga teorier som är relevanta för undersökningen. Rapporten redogör för befintliga teorier som är relaterade till platsoberoende arbete, agil utveckling, scrum utveckling samt hur effektivitetet av scrum-utveckling kan mätas. / The purpose of this thesis is to map how individuals experience remote scrum development, what problems arise and whether efficiency is affected. In order to achieve the purpose of the study and answer the research-questions formulated in the report, data has been collected. This data has been partly quantitative, where data has been collected from a business that conducts system development with the methodology scrum. Data has also been qualitative where data in the form of interviews have been collected. The collected data has then been analyzed in order to answer the research questions. After completing the analysis, conclusions have been drawn in order to fulfill the thesis' original purpose. The collected empirical evidence indicates that certain problems related to communication become clear when the work is conducted remote. The data collected also indicates a deteriorating experience of the social environment when the work is conducted remote. Finally, the analyzed result also indicates a reduced efficiency when the work has shifted to remote. The theoretical framework is the basis for presenting existing theories that are relevant to the study. The report describes existing theories that are related to site-independent work, agile development, scrum development and how the effectiveness of scrum development can be measured.
