Assessing Information Loss in EPC to BPMN Business Process Model Transformation

Much research work has been discussing the transformation between different process modeling languages. The focus was often put on model syntax rather than on the integrity of process content. Here an established approach for evaluating information content is used to assess the information content change that results due to process model transformation from EPC to BPMN business process representation. The results show that induced information change is not significant and provides insights into EPC and BPMN language structures. Contribution of this paper is thus a generic strategy for information content measurement in business process models as well as information theoretical view on business process modeling notations. The findings have implications for analysts and modelers in that they provide guidance on language choice and reduce uncertainty of model transformation.
