   Abstract:
   The provision of business services, in practice, exhibits the processes of several organisations, run in parallel for their local stakeholders, with points of synchronisation serving to coordinate the differently executing parts. Current workflow tools restrict business process coordination to single workflows. This means different processing parts are unnaturally coupled into the same unit of modularity, thereby restricting workflow reusability. We demonstrate three extensions which serve to coordinate the execution of concurrently executing and interdependent workflows: the adaption of synchronous and asynchronous messaging for inter-workflow communication, the aborting of inter-related execution paths for coordinated exception handling and the exclusive, i.e. atomic, execution of nested processes in the context of concurrently executing processes. These extensions are applied at the conceptual level of specification, illustrated through highlights from an industrial case study and assigned a formal semantics
