Thinging the Use Case Model

10/07/2019 ∙ by Sabah Al-Fedaghi, et al. ∙ 0

Use cases as textual visual modeling techniques have become a key construct and the foundation of the most popular de facto standard technique for performing software requirements analysis and specification. This paper describes use cases in terms of a recently proposed model, the thinging machine (TM) model. Such a link to TM strengthens the notion of use cases and clarifies related concepts. For example, the concept of events is utilized in an unconstrained way in use cases, and TM may contribute in this direction. Several selected use cases are remodeled using TM. This study provides many insights. For example, one result shows that use cases are an activation apparatus of mega-triggering (high-level events) wherein a group of submachines (processes) are actuated.
