Correlation Engine
Correlation Engine is a concept raised in the Event Management process contained with the Service Operation volume of the new ITIL version 3.
The Correlation Engine is an intelligent processing unit that contains business rules (which are formulated as part of Service Design). Event Correlation is one of the activities of the event management process and it is here that an event is assessed, before an event trigger is generated that determines the response selection for the specific event.
The correlation engine is first assesmbled during the Service Design phase, but the business rules it contains are continually updated as part of feedback received from Operations Mangement and the Problem Management process
