A Pattern-Based and Model-Driven Approach for Deriving IT System Functional Models from Annotated Business Models

Abstract

Companies increasingly demand IT systems to support (part of) their business. In order to maximize return on investment, these systems need to be perfectly aligned both with the business and with the legacy applications with which they will be integrated. In this vein, this paper presents a pattern-based and model-driven approach for deriving IT system functional models from annotated business models. First, we explain how to annotate the BPMN 2 business models with information useful for deriving the functionalities. Then, we introduce a set of patterns aimed to help identifying the functionalities and the relationships existing among them from the annotated business models. Finally, we present an ATL model transformation that, based on the previous patterns, allows us to obtain UML2 Use Case Diagrams.
