following constructs: An action is an object neutral description of activities: a verbal description of a work task, a lawsuit or proceeding; A function describes the change of state of a defined status into another defined one of objects of a class by using an action; and An activity specifies necessary resources for the state transformation of objects of a class the controlling order described by a function and these for the execution of this transformation in the enterprise, in each case represented by an object state description. Views All modeled data of the looked-at-enterprise are recorded in the model core of an Integrated Enterprise Modeling (IEM) model in two main views: the "information model"; and the "business process model". All relevant objects of an enterprise, their qualities and relations are shown in the "information model". It is class trees of the object classes "product", "order" and "resource" here. The "business process model" represents enterprise processes and their relations to each other. Activities are shown in their interaction with the objects. Process modeling The structuring of the enterprise processes in Integrated Enterprise Modeling (IEM) is reached by its hierarchical subdivision with the help of the decomposition. Decomposition means the reduction of a system in a partial system which respectively contains components which are in a logical cohesion. The process modeling is a partitioning of processes into its threads. Every thread describes a task completed into itself. The decomposition of single processes can be carried out long enough until the threads are manageable, i.e. appropriately small. They may turn out also not too rudimentary because a high number of detailed processes increases the complexity of a business process model. A process modeling person, therefore, has to find a balance between the effort complexity degree of the model and possible detailed description of the enterprise processes. A model depth generally recommends itself with at most three to four decomposition levels (model levels). On a model level business process flows are represented with the aid of illustrated combination elements. There are these five basic types of combinations between the activities: Sequential order: At a sequential order the activities are executed after each other. Parallel branching: A parallel branching means that all parallel branched activities to be executed have to be completed before the following activity can be started with. It is not necessary that the parallel activities are executed at the same time.
