Abstract : In the context of Services Oriented Architecture (Soa), com- plex systems are realized through the design of business–driven processes. Since the design of a complete process can be very complex, composi- tion tools such as aspects and features propose to define large systems by composing smaller artifacts (more easy to understand) into a com- plex one. But these techniques shift the system complexity into the def- inition 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 compositions of business–processes and then identify patterns and categorization. We use the Adore framework as underlying process composition platform. We validate this work by presenting in this article instance of these visualizations obtained from a Car Crash Crisis Man- agement system (CCCMS, a comparison referential for Aspect Oriented Modeling techniques). We use these visualization to assess the Cccms realization.
