In this paper we propose an approach to treat business rules as a separate component of business model used in business process deployment. Using this approach, we can define, customise and deploy business processes that are directly dependent upon business rules. Moreover, business rules can be applied efficiently and consistently to a business process. Furthermore, we are able to incorporate these rules into another business process, where each process depends upon some specific rules, policies, procedures and standards. The approach also provides the flexibility to allow business process automation to be more customisable, flexible, efficient and reusable.
