Towards rule-based pattern perspective for BPMN 2.0 business process models

Rules and processes constitute powerful representation forms. Although the same notions can be expressed in both of these representations, there is a significant difference in abstraction levels between processes and rules. In practice, rules are mostly used for the specification of rule task logic in processes. In this paper, we present various options where and how rules can be perceived in business processes. We introduce rule-based pattern perspective for process models, focusing on BPMN 2.0 Business Process Models.
