Visualizing Use Case Sets as BPMN Processes

The goal of many software projects is the support of business processes. A typical business process spans multiple Use Cases. This poses the difficulty of making the set of encompassing Use Cases consistent with each other and functionality-wise complete with regards to the overall business process. Manual arrangements and reviews of Use Cases are burdensome and time-intensive. Therefore, an automatic approach is needed that restores an overview of the Use Cases and visualizes the control-flow of the resulting business process. Our approach uses pre-conditions, post-conditions, and triggers of Use Cases to automatically assemble business processes in BPMN notation in order to solve this problem.
