Rather new concepts like Model Driven Architecture (MDA) or Service Oriented Architecture (SOA) will make it necessary to focus more on the top layers of enterprise tier architecture, that is to say system modeling and dynamic process management. The methodologies of systems theory provide the theoretical foundation and have to be the starting point for system modeling efforts, not the given IT-infrastructure or particular processes as it can be found widespread. Of course domain analyse and modeling is an ambitious objective, many projects failed in the past because of system complexity and variety in combination with the therefore necessary data, structural and behavioural views. We want to present an modeling approach which focuses on functionalities in an very heterogeneous environment divided in encapsulated subsystems, namely the shop floor. According to the SOA paradigm, which postulates platform independent and dynamic functionality invocation in a distributed environment via services, hiding the behind structure and behaviour, we build up a service repository for the shop floor, adding data entities and roles which are needed for process description. Hence we do not consider service realization, but only the control and data flow between the services, system complexity and variety is reduced to a level which makes UML constructs handsome and promising tools for modeling and monitoring process life cycles.
