Process Implementation with Executable Models

Abstract

In the previous chapters, we learned how to create conceptual process models and use them for documentation and analysis purposes. Because of their purpose, these models are intentionally abstract in nature, i.e., they do not provide technical implementation details. This means that conceptual process models must be systematically reworked into executable process models to be interpreted and automatically executed by a software system, such as a BPMS. In this chapter, we propose a five-step method to incrementally transform a conceptual process model into an executable one, using the BPMN language. As part of this method, we also show how to make use of two other standards complementary to BPMN: CMMN and DMN.
