A typical composite Web service is built of basic Web services, both internal and external, over which the integrator does not have a complete control. The service-based integration of enterprise systems raises the need for the analysis of non-functional characteristics of a composite Web service. Such an analysis should cover dependability (for instance, the reliability of the main process, sensitivity analysis on component reliability, etc.) and performability aspects (e.g. determining the optimal process structure for a given level of reliability) as well. The paper discusses how graph transformations can be used to adapt formal methodologies for analyzing SOA models. This way a flexible and extendable analysis framework can be developed for Web service-based business processes.
