Abstract
The necessity of aligning an enterprise's Information System (IS) model to its Business Process (BP) model is incontestable. However, the main difficulty of establishing/maintaining BP-IS models alignment stems from the dissimilarities in the knowledge of the information system developers and the business process experts. To face these predicaments, we propose a Model Driven Architecture (MDA) compliant methodology that aims to automate the generation of UML models from BPMN models. It allows mastering transformation from Computation Independent Model (CIM) to Platform Independent Model (PIM). The CIM level expresses the BP, which is modelled through the standard BPMN (Business Process Modelling Notation) and, at the PIM level represents the aligned, IS model is generated as use case diagram. Its originality resides in the CIM to PIM transformation which accounts for the BP structural and semantic perspectives in order to generate an aligned IS model that respects the best-practice granularity level of a use case.
