Quality metrics for business process modeling

Modeling business processes is vital when improving or automating existing business pocesses, documenting processes properly or comparing business processes. In addition, it is necessary to be able to evaluate the quality of a business process model, which in tern requires a set of quality metrics. Most of the works proposed to evaluate business process models deal with quality by adapting software metrics. This is possible, because software products and business processes software are quite similar. Our contribution in this paper consists in adapting object oriented software metrics to business process models. This adaptation is based on correspondences which we establish between BPMN (Business Process Modeling Notation) concepts and object oriented concepts. By adapting object oriented metrics, we aim to obtain new metrics which give us more information about the complexity of business processes, cohesion between process tasks and coupling between processes themselves.
