The reuse of existing business parts offers a solution to the business process flexibility and the business agility for the information system. Indeed, to reach this flexibility, a solution can be done by the reuse of business fragments to create or to adapt another business process (BP). These business fragments can be obtained from the decomposition of functional business process into small business units. The aim of this paper is to propose an approach for business process decomposition using BPMN. The proposed approach is presented as pattern.
