Compositional verification of business processes modelled with BPMN

Abstract:

A specific check that is required to be performed as part of the Business Process Modelling (BPM) is on whether the activities and tasks described by Business Processes (BPs) are sound and well-coordinated. In this work we present how the Model-Checking verification technique for software can be integrated within a Formal Compositional Verification Approach (FVCA) to allow the automatic verification of BPs modelled with Business Process Modelling Notation (BPMN). The FVCA is based on a formal specification language with composition constructs. A timed semantics of BPMN defined in terms of the Communicating Sequential Processes + Time (CSP+T) extends untimed BPMN modelling entities with timing constrains in order to detail the behavior of BPs during the execution of real scenarios that they represent. With our proposal we are able to specify and to develop the Business Process Task Model (BPTM) of a target business system. In order to show a practical use of our proposal, a BPTM of an instance of a BPM enterprise-project related to the Customer Relationship Management (CRM) business is presented.
