In this paper, we investigate whether the guideline to use verb-object labels actually contributes to improved model quality in terms of less ambiguity and higher usefulness. In an explorative analysis of the activity labels in the SAP Reference Model we identify three labeling styles that differ in the degree of ambiguity they bring about. Based on these styles we design a survey to test the hypothetical connection between labeling style and quality. The results suggest that indeed the verb-object style is superior to other ways of constructing labels. Our findings are deemed to be useful for modeling practice.enBusiness Process Modeling and ERP SystemsConceptual ModellingEvaluations of Systems Analysis and Design Modelling Methods and TechniquesWorkflow ManagementText/Conference Paper1617-5468
