Abstract. In the context of Services Oriented Architecture (Soa), complex systems are realized through the design of business–driven processes. Since the design of a complete process can be very complex, composition tools such as aspects and features propose to define large systems by composing smaller artifacts (more easy to understand) into a complex one. But these techniques shift the system complexity into the definition of composition directives able to build it. At composition time, process designers needs to be supported to understand and assess their designed systems. We propose in this article a set of visualizations to represents composition and then identify patterns and categorization. We use the Adore framework as underlying composition platform. We validate this work by presenting in this article instance of these visualizations obtained from a Car Crash Crisis Management system (CCCMS, a comparison referential for Aspect Oriented Modeling techniques). We use these vi...
