Analysis and validation of control-flow complexity measures with BPMN process models

Abstract

Evaluating the complexity of business processes during the early stages of their development, primarily during the process modelling phase, provides organizations and stakeholders with process models which are easier to understand and easier to maintain. This presents advantages when carrying out evolution tasks in process models - key activities, given the current competitive market. In this work, we present the use and validation of the CFC metric to evaluate the complexity of business processes modelled with BPMN. The complexity of processes is evaluated from a control-flow perspective. An empirical evaluation has been carried out in order to demonstrate that the CFC metric can be useful when applied to BPMN models, providing information about their ease of maintenance. © 2009 Springer Berlin Heidelberg.
