Transforming use case maps to the core scenario model representation

Scenarios describe system functionalities and, when supplemented with performance annotations, provide a basis for performance analysis. This thesis presents a Core Scenario Model (CSM), which includes common scenario information in the Use Case Maps (UCM) notation and in UML 2.0 activity diagrams and interaction diagrams. The intent is to enable automatic transformations from a given scenario model to CSM, and then from a CSM model to performance models, hence enabling performance analysis early in the development process. CSM captures scenarios, performance, and deployment information, and is flexible enough to support multiple input scenario notations and output performance languages. The thesis also includes a transformation from UCM models to CSM. Such automatic transformation enables the quick generation of performance models, ready to be analyzed. The results from performance analysis can be traced back to improve design decisions and any changes in design can be updated in performance models quickly through re-generation
