In response to a growing complexity within the value creation in companies as well as in supply chain networks, corporate decision making tasks are primarily organized in a function-oriented way. This functional orientation is inevitably reflected in departmental objectives and corresponding objective systems which define the possible optimization strategies with respect to the decision making tasks of individual departments. Based on such department-specific objective systems, the development of conflicts of objectives between departments can be observed. This paper proposes a model-based approach to create systematization for describing interdepartmental conflicts of objectives. Based on actuating variables, control variables, result variables and objectives, the objective systems and measures of individual departments are interlinked and integrated in a cybernetic model. This cybernetic model allows the description of significant cause-effect relationships between the departments in order productions. Additionally, the impacts of the decisions of individual departments on the objective systems of other departments can be derived from the model. The model as developed is restricted to the objective system of order productions but can be transferred by way of pertinent adaptations and extensions of the specific objective system to other order fulfillment processes. The transparent presentation of interdepartmental cause-effect relationships makes it possible to increase collaboration between departments. Departments are empowered in the cybernetic model to align and optimize their actions to reflect overall corporate goals and the objective systems of other departments. Furthermore, in addition to the existing empirically motivated studies, the introduced model can expand the systematic development of collaboration in companies.
