Integrated enterprise modeling (IEM) is an enterprise modeling method used for the admission and for the reengineering of processes both in producing enterprises and in the public area and service providers. In integrated enterprise modeling different aspects as functions and data become described in one model. Furthermore, the method supports analyses of business processes independently of the available organizational structure. The Integrated Enterprise Modeling is developed at the Fraunhofer Institute for Production Systems and Design Technology (German: IPK) Berlin, Germany.
