Recker (2010) makes a related point post analysis of 120 BPMN models. Interested in the frequency of occurrence of all 50 BPMN constructs he identified a relatively small set frequently used: normal flow, task, start/end events, pool, data-based XOR. Recker (2010, p. 192) argues that “there is a core of BPMN symbols used for the simple documentation
of organisational processes” with the majority remaining either limited to specialist application (e.g. process orchestration) or unnecessary overhead.
