Does Experience Matter? Factors Affecting the Understandability of the Business Process Modelling Notation

This study proposes and tests an instrument for measuring the understandability of the selected business process modelling notation. Based on empirical research, we evaluated differences in the understandability of business process modelling notations between the groups of respondents, experienced and inexperienced in business processes modelling, and we identified the features of notations that determine the understandability of the modelling technique. Three notations were subjected to the diagnosis: EPC, BPMS, and BPMN. The analysis of differences in the understanding of a notation may be helpful when testing the process-related competence of people participating in process modelling and analysis projects.
