Integrating goal-oriented and use case-based requirements engineering: The missing link

Combining goal-oriented and use case modeling has been shown as an effective method of requirements engineering. To ensure the quality of such modeled artifacts, a conceptual foundation is needed to govern the process of determining what types of artifacts to be modeled, and how they should be specified and analyzed for 3Cs problems (completeness, consistency and correctness). However, such a foundation is missing in current goal-use case integration approaches. In this paper, we present GUIMeta, a meta-model, to address this problem. GUIMeta consists of three layers. The artifact layer defines the semantics and classification of artifacts and their relationships. The specification layer offers specification rules for each artifact class. The ontology layer allows semantics to be integrated into the entire model. Our promising evaluation shows the suitability of GUIMeta in modeling goals and use cases.
