In December 2005, the OGC issued notice of an ITIL refresh,[2] commonly known as Information Technology Infrastructure Library v3 (ITIL v3). The project culminated in the publication of five new core texts and a web based glossary on 30 May 2007. The ITIL Refresh project is being led by Sharon Taylor, chief architect of the ITIL Refresh, and president of the Aspect Group.
A key change to ITIL under version 3 has been a repositioning of the framework from the previous emphasis on process lifecycle and alignment of IT to "the business", to the management of the lifecycle of the services provided by IT, and the importance of creating business value rather than just the execution of processes. Consequently, it was rebranded ITIL Service Management Practices in order to represent service management 'best practice'. It is a publicly stated aim of the refresh to include more reference to ROI.
[edit] Version 3 structure
ITIL v3 comprises a set of core texts supported by additional complementary and web based materials. While the version 2 volumes were only available in English, limiting their use in non-English speaking countries, the core titles in version 3 are being translated into other languages. Among the initial target languages are Portuguese, Spanish, Japanese, Hindi/Urdu, Arabic, Mandarin and Dutch. This initiative is being led by the IT Service Management Forum, with resources and support from OGC.
[edit] ITIL v3 core volumes
* Service Strategy focuses on the identification of market opportunities for which services could be developed in order to meet a requirement on the part of internal or external customers. The output is a strategy for the design, implementation, maintenance and continual improvement of the service as an organizational capability and a strategic asset. Key areas of this volume are Service Portfolio Management and Financial Management.
* Service Design focuses on the activities that take place in order to develop the strategy into a design document which addresses all aspects of the proposed service, as well as the processes intended to support it. Key areas of this volume are Availability Management, Capacity Management, Continuity Management and Security Management.
* Service Transition focuses on the implementation of the output of the service design activities and the creation of a production service or modification of an existing service. There is an area of overlap between Service Transition and Service Operation. Key areas of this volume are Change Management, Release Management, Configuration Management and Service Knowledge Management.
* Service Operation focuses on the activities required to operate the services and maintain their functionality as defined in the Service Level Agreements with the customers. Key areas of this volume are Incident Management, Problem Management and Request Fulfillment. A new process added to this area is Event Management, which is concerned with normal and exception condition events. Events have been defined into three categories:
o Informational events -- which are logged
o Warning events -- also called alerts, where an event exceeds a specified threshold
o Critical events -- which typically will lead to the generation of Incidents
* Continual Service Improvement focuses on the ability to deliver continual improvement to the quality of the services that the IT organization delivers to the business. Key areas of this volume are Service Reporting, Service Measurement and Service Level Management.
ITIL v3 uses the word "continual" as opposed to ITIL v2's references to "continuous" service improvement (CSIP). Continual implies an activity that is undertaken on a phased, regular basis as part of a process. Continuous is more suitable for the definition of activities intended to operate without pause, such as the ultimate goal of availability.

Criticisms of ITIL
ITIL has been criticized on several fronts, including:
* The books are not affordable for non-commercial users
* Accusations that many ITIL advocates think ITIL is "a holistic, all-encompassing framework for IT governance";
* Accusations that proponents of ITIL indoctrinate the methodology with 'religious zeal' at the expense of pragmatism.
As Jan van Bon (author and editor of many IT Service Management publications) notes,
There is a lot of confusion about ITIL, stemming from all kinds of misunderstandings about its nature. ITIL is, as the OGC states, a set of best practices. The OGC doesn’t claim that ITIL’s best practices describe pure processes. The OGC also doesn’t claim that ITIL is a framework, designed as one coherent model. That is what most of its users make of it, probably because they have such a great need for such a model...[17]
CIO Magazine columnist Dean Meyer has also presented some cautionary views of ITIL,[18] including five pitfalls such as "becoming a slave to outdated definitions" and "Letting ITIL become religion." As he notes, "...it doesn't describe the complete range of processes needed to be world class. It's focused on ... managing ongoing services."
The quality of the library's volumes is seen to be uneven. For example, van Herwaarden and Grift note, “the consistency that characterized the service support processes … is largely missing in the service delivery books."[19]
In a 2004 survey designed by Noel Bruton (author of 'How to Manage the IT Helpdesk' and 'Managing the IT Services Process'), ITIL adopting organizations were asked to relate their actual experiences in having implemented ITIL. Seventy-seven percent of survey respondents either agreed or strongly agreed that "ITIL does not have all the answers". ITIL exponents accept this, citing ITIL's stated intention to be non-prescriptive, expecting that organizations will have to engage ITIL processes with their existing overall process model. Bruton notes that the claim to non-prescriptiveness must be at best one of scale rather than absolute intention, for the very description of a certain set of processes is in itself a form of prescription. (Survey "The ITIL Experience - Has It Been Worth It", author Bruton Consultancy 2004, published by Helpdesk Institute Europe, The Helpdesk and IT Support Show and Hornbill Software.)
While ITIL addresses in depth the various aspects of Service Management, it does not address enterprise architecture in such depth. Many of the shortcomings in the implementation of ITIL do not necessarily come about because of flaws in the design or implementation of the Service Management aspects of the business, but rather the wider architectural framework in which the business is situated. Because of its primary focus on Service Management, ITIL has limited utility in managing poorly designed enterprise architectures, or how to feed back into the design of the enterprise architecture.
The BOFH notes that “ITIL manuals are like kryptonite to enthusiasm."
