Business process modelling in the context of SOA – an empirical study of the acceptance between EPC and BPMN

The successful introduction and use of service oriented architecture (SOA) is based on its symbiosis with the business process management (BPM). A precisely targeted usage of process modelling is an integral part of BPM. Event-driven process chains (EPC) and the business process modelling notation (BPMN) are the first choice for the process-oriented modelling. Business process execution language (BPEL) processes can be generated from both these models. They orchestrate the services of the SOA platform, thus, leading to the new IT applications without much expensive programming. The following contribution will introduce the results of an empirical survey on the acceptance comparison of EPC and BPMN.
