On the Cognitive Effectiveness of Routing Symbols in Process Modeling Languages
Process models provide visual support for analyzing and improving complex organizational processes. In this paper, the authors discuss differences of process modeling languages using cognitive effectiveness considerations, to make statements about the ease of use and quality of user experience. Aspects of cognitive effectiveness are of importance for learning a modeling language, creating models, and understanding models. They identify the criteria representational clarity, perceptual discriminability, perceptual immediacy, visual expressiveness, and graphic parsimony to compare and assess the cognitive effectiveness of different modeling languages.
