Abstract

Requirements refinement is not only a process to derive specifications, but also a necessary means towards preparing architectural designs. In this paper, we present a novel refinement framework, comprising methods and process, to move from requirements to design. The framework consists of multiple abstraction levels capturing requirements of different kind and granularity, allows the derivation of designer and user perspectives separately, introduces stages of activities to be carried out in the process, includes refactoring-based methods to carry out the refinement, and provides a structure that allows easy traceability between requirements.
