Proposal of square metrics for measuring Business Process Model complexity

Business Process (BP) metrics are used for controlling the quality and improving models. We give an overview of the existing metrics for describing various aspects of BP models. We propose simple yet practical square metrics for describing complexity of a BP model. These metrics are easy to interpret and provide some basic information about the structural complexity of the model. The proposed metrics are to be used with models built with Business Process Model and Notation (BPMN). It is currently the most widespread language used for BP modeling.
