Reference Model for the Design of Compatible ERP-Modules in the Machinery and Equipment Industry

摘要

Companies today face the challenge to encounter increasing market dynamics with the help of rather static IT-systems. Especially the monolithic ERP-systems require high cost and time efforts for adaptation and lead to the use of additional, non-integrated applications in order to serve process requirements in producing companies. This leads to a fragmented IT-system-landscape that prohibits a real-time, valid representation of the as-is situation and that is barely adaptable. This significantly limits a company's ability to detect deviations and to govern the order management under dynamic conditions. The paper at hand focuses on a comprehensive research project dealing with modularization of ERP systems into compatible modules that can be configured to a whole system within the approach of a service oriented architecture. An integrated information management model regarding the IT-support for order management processes within the engineer-to-order production is developed. Combining process activities with the perspective of data-flows and IT-functionalities, the model builds the bases for the clustering of IT-functionalities to ERP-modules and the design of their respective interfaces.
