The purpose of business process diagrams is mainly to make the communication between process-related stakeholders more effective. Currently, BPMN (Business Process Model and Notation) is the leader and de-facto standard for business process modeling. However, the notation and their corresponding diagrams have been perceived as complex by many different researchers. Much work was already done in order to manage such complexity by changing or extending the existing BPMN notation. In this paper, we will propose a solution that aims to decrease the complexity of business process diagrams without changing the notation or existing approaches by introducing opacity-driven graphical highlights.
