*Email: nqhung@gmaiI,com ABSTRACT
With the high demands for business agility and reducing costs, BPM tends to move to "Dynamic Business Process Management" and "Intelligent Case Management"
rather than isolate process flows. Business rules and business processes are important factors in determining the requirements of a software system especially in Business Process Management Systems. Although business rules and processes are considered core components of "Business Process Management", both of them are not sufficient to represent all business constructs. In this study, we have compared business process and business rule modeling languages in order to show that no single language is complete with respect to the BWW (Bunge-Wand- Welwr) representation model. Basing on this comparision, we have proposed the integration between BPMN and SBVR in order to meet the entire business construct of business process in accordance with the BWW model.
Keywords: Business Process Management, business rule, business process.
