Abstract. Today’s enterprises are dynamic where many variances of businessprocess models can exist due to several reasons such as: the need to target differ-ent customer types, rely on particular IT systems or comply with speciﬁc countryregulations. Automated maintenance of the consistency between process variantsis an important goal that saves the time and efforts of process modelers. In thispaper, we present a query-based approach to maintain consistency among processvariants. We maintain the link between the variant process models by means ofdeﬁning process model views. These views are deﬁned using, BPMN-Q, a visualquery language for business process models. Therefore, dynamic evaluation forthe deﬁned queries of the process views guarantee that the process modeler isable to get up-to-date and consistent status of the process model. In addition, ourview-based approach allows the building of a holistic view of related variants ofthe same process model. Keywords: Business process design, Reuse, Querying business processes, Pro-cess variants.
