Common BPMLs such as BPMN 2.0 or EPC are widely accepted and applied in various domains. However, such BPMLs provide a set of generic process modeling elements but do not allow for modeling domain specific concepts. This also holds true for control means as one of the key concepts for process audits. To address this gap, this paper presents an empirically grounded extension of the EPC with modeling concepts for process-integrated control means. The results of a laboratory experiment with 58 participants demonstrate that the extension facilitates a comprehensive enactment of process audits. In conclusion, the results of this research project are contrasted with a previously designed BPMN 2.0 extension in order to present insights we gain from extending two different BPMLs with the same domain concept.enExtending different business process modeling languages with domain specific concepts: the case of internal controls in EPC and BPMNText/Conference Paper1617-5468
