The information system performance depends on the operational efficiency of the implemented business processes, but also on their ability to meet the non-functional requirements, especially those of performability (performance and reliability). Indeed, the modelling phase of business processes is a critical phase within the BPM (Business Process Management) lifecycle. Nevertheless, the notation BPMN (Business Process Model and Notation) which is the de facto standard for business process modelling, is limited to the contemplative modelling of their behavior enabling developers to capture their functional requirements. As part of a productive modelling approach, integrating performability requirements of business processes at design-time is essential to enable their automatic analysis and to predict their quality of service. This article classifies and compares contributions among the most recent or referenced in this field. The aim is to highlight their limitations and to identify the criteria of an efficient approach.
