But if the business decides that this promotion is bringing in a lot of new customers and it wants to keep the promotion going, this can be done easily by changing the decision in the event specification. As in the business rules case, the objectives of agility and governance cannot be achieved unless both the definition of the business circumstances that make up the event and the corresponding decision-based actions are accessible and visible to the business community. Business Event Processing (BEP) performs equivalent functions to BRMS, providing a business-user interface for authoring, editing and viewing both the event conditions and the related actions (or rules), and the technical support to detect the defined event during operations and trigger the specified actions.

These decision-making rules are then either invoked synchronously within each execution instance of the process, or are triggered by event technology that enables them to be driven asynchronously when a set of circumstances occur. However it is important to understand that operational decision making can be used within any IT activity, not just those govern...
