The new core ITIL titles have been commissioned and structured to be read as a five title series, each building on the work of the other. As the five core titles reflect the lifecycle of services, their appeal encompasses the entire spectrum of people involved at any stage of the framework. So, without being the prime audience, everyone involved will benefit from access to the entire library. Publications in the Suite: Service Strategy, Service Design, Service Transition, Service Operation, Continual Service Improvement. The suite of titles offers considerable costs savings against purchasing all five titles individually.
