A model-driven approach to semi-automatic manage IT based business processes implies to interlink language concepts of the business and IT domain. The paradigm of service-oriented architecture provides a technological basis for reacting to business requirements in a distributed application environment. Services encapsulate functionality to be reused in different processes and can be easily described in design models that should be the result of analyzing the business requirements described in conceptual models. However, this process is nontrivial, iterative, and cannot be fully automated. This paper presents an approach to introduce artifacts to establish a consensus on language level which enhances the comparability of models and allows to semi-automate the transformation process by weakening the strict separation of language creation and language usage.
