Abstract

BPMN 2.0 is an OMG standard and one of the leading process modelling notations. Although the current language specification recognises the importance of defining a visual notation carefully, it does so by relying on common sense, intuition and emulation of common practices, rather than by adopting a rigorous scientific approach. This results in a number of suboptimal language design decisions that may impede effective model-mediated communication between stakeholders. We demonstrate and illustrate this by looking at BPMN 2.0 through the lens of the Physics of Notations, a collection of evidence-based principles that together form a theory of notation design. This work can be considered a first step towards making BPMN 2.0's visual notation more cognitively effective.
