Business Process Verification: The Application of Model Checking and Timed Automata

The most important result to standardize the notation for graphical representation of Business Processes (BPs) is the Business Process Model and Notation (BPMN). Despite the BPs modeled with BPMN being able to support business designers, BPMN models are not appropriate to support the analysis phase. BPMN models have no formal semantics to conduct qualitative analysis (validation and verification). In this work is presented how Model Checking (MC) verification technique for software and Timed Automata (TA) formal language are integrated within a formal verification approach to check BPs modeled with BPMN. Also, are introduced a set of guideline to transform BPMN models into TA. The use of our approach allow to business analysts and designers to perform evaluation (i.e., qualitative analysis) of BPs, based on the formal specification of BP–task model with TA. The application of the approach is aimed to evaluate the behavior of the BP–task model with respect to business performance indicators (for instance, service time, waiting time or queue size) derived from business needs, as is shown in an instance of an enterprise–project related to Customer Relationship Management.
