Beyond Soundness: On the Semantic Consistency of Executable Process Models
Executable business process models (like BPEL-based Web service orchestrations) build on the specification of process activities, their implemented business functions (e.g., Web services) and the control flow between these activities. Before deploying such a model, it is important to verify control-flow correctness. A process is sound if its control-flow guarantees proper completion and there are no deadlocks. However, a sound control flow is not sufficient to ensure that an executable process model indeed behaves as expected.
