A Quality Model for Requirements Management Tools

Abstract:

This chapter proposes the use of quality models to describe the quality of requirements management tools. We present the COSTUME (COmposite SofTware system qUality Model development) method aimed at building ISO/IEC 9126-1-compliant quality models, and then we apply it to the case of requirements management. We emphasize the need to use UML class diagrams to represent the knowledge about the domain prior to the quality model construction, and also use actor-based models to represent the dependencies of requirements management tools with their environment, and then comprehend better the implications of quality factors. We show the applicability of the quality model in a real experience of selection of a requirements management tool.
