A service-oriented method for domain and business process modelling

In this paper, we present Precise SOM (Precise Service Oriented Modelling) —a novel lightweight method for integrated domain and business process modelling—which follows the service-oriented paradigm, uses a UML profile as notation and provides detailed workflows to guide the production of the models. In our method, the UML models are precisely defined by means of a metamodel and of a set of constraints, and by restricting UML to the essential language constructs, to help modellers to avoid common mistakes and to guarantee, by construction, a good quality. Precise SOM has been validated by detailing how it can be used in various modelling tasks, some of them illustrated by a (industrial) case study.
