A quality performance model for cost-benefit analysis of non-functional requirements applied to the mobile handset domain

Research output: Chapter in Book/Report/Conference proceedingPaper in conference proceeding


In market-driven requirements engineering for platform-based development of embedded systems such as mobile phones, it is crucial to market success to find the right balance among competing quality aspects (aka nonfunctional requirements). This paper presents a conceptual model that incorporates quality as a dimension in addition to the cost and value dimensions used in prioritisation approaches for functional requirements. The model aims at supporting discussion and decision-making in early requirements engineering related to activities such as roadmapping, release planning and platform scoping. The feasibility and relevance of the model is initially validated through interviews with requirements experts in six cases that represent important areas in the mobile handset domain. The validation suggests that the model is relevant and feasible for this particular domain.
