Projections of Abstract Interorganizati...

Distributed interorganizational business processes are constituted by cooperating private processes of different partners. These private processes must be aligned to fulfill the overall goal of the (virtual) interorganizational process. Process views are considered as an excellent concept for modeling such interorganizational processes by providing a good balance between the information needs and privacy requirements of the partners. We follow a top-down development approach, where first an abstract global process is designed. Then each task of the global process is assigned to one of the partners. Finally, a partitioning procedure is applied to generate views of the global process for each partner. The partners can then develop or adopt their private processes based on their views. We present a novel algorithm for the automatic partitioning of any block-structured process with any arbitrary assignment of partners and have proven its correctness.
