Top-Down Design of Collaborating Proces...

Interorganizationalbusiness processes aim to integrate local processes to support the seamlesscooperation of organizations. Process view approaches are an adequate methodbalancing the communication requirements for enabling collaboration and therequired privacy hiding internals of private business processes. We focus on atop-down scenario for the development of interorganizational processes, wherefirst an abstract global process is designed. Then each step of the globalprocess is assigned to one of the partners and a local process is generated foreach partner as a view on the global process. Finally, the partners implementor adopt their processes based on their views. We present an algorithm for the fullyautomatic generation of views for any block-structured input process witharbitrary partner assignments, provide a method for merging the partner's viewsto reconstruct the global process and prove the correctness of the viewgeneration method.
