This sort of verbal obfuscation is what gives PROCESS a bad name… !
What we really mean is this. We increasingly have to think of IT as more than a collection of technical bits (servers, databases etc.) We need to think of IT as being a SERVICE and that we, as technical people and professionals, SUPPORT that Service. We then DELIVER that Service to the BUSINESS, for the purpose of making MONEY.
When we start thinking of IT as a Service, then we start thinking about how do we manage it better. Say “what are we trying to achieve overall?” Rather than “what does this team do?”
ITIL was conceived by the British Government who approached various organisations and experts to write the books which were originally published in the 1980s. These were revised in 2001 and 2002, and the library has expanded in scope since then. The latest version is being developed for publication in 2007.
Sometimes these methodologies can get in the way, sometimes they help. Either way, they can be useful, if you “pick-and-choose” what will help you. And remember - ITIL is NON-PRESCRIPTIVE - IT does not demand that you do anything!
Just as PRINCE2 is a methodology, an approach, which can be used successfully by development teams to manage projects, So ITIL is an approach, a set of “best practices” for managing the day-to-day support activities in Production.
This is what the ITIL library actually consists of. Recently Added: Introduction to ITIL Software Asset Management Small-Scale Implementation
As mentioned, the key volumes are SERVICE DELIVERY and SERVICE SUPPORT. They are often what is called “Core ITIL”. Most people, when they talk about ITIL, are thinking of these two books only, and the chapters in them. So, when we talk about ITIL, we need to understand what is meant by these 11 topics.
Fact One: The books themselves are meant to guide; they are not steadfast laws. None of the authors, contributors or publishers ever expected organizations to adhere to every word of their publications. Fact Two: You can't implement ITIL with just processes and technology. You must address the people involved as well. ITIL demands attention to three components: people, process and technology. Changes in process improve efficiency and effectiveness. Changes in technology reduce costs and accelerate responsiveness. But you ultimately have to change people to develop the culture you need to better support the business and optimize availability of critical IT services. (Brian Johnson)
What is the it SMF? A not-for-profit organisation owned by its members, the it SMF is a major influence on, and contributor to, industry b est practice , Standards and personal development, working with a wide range of governmental and standards bodies worldwide.Formed in the UK in 1991, there are now national chapters in an ever-increasing number of countries. There is an International body that guides and supports existing and emerging chapters, their website is www. itsmf .org .

Time for Questions…
The ITIL definition of IT “Service” - is this helpful ?? “ An integrated composite that consists of a number of components such as management processes, hardware, software, facilities and people that provides a capability to satisfy a stated management need or objective.” Dictionary of IT Service Management
Think of MANAGING IT as PROVIDING a SERVICE £ IT SERVICE SERVICE DELIVERY SERVICE SUPPORT BUSINESS Align IT services with the needs of the Business Improve the Quality of the Service Reduce the long-term costs
Think in terms of PROCESSES rather than SKILLS Functional Organization Process Approach Using a Process Approach, we no longer think in terms of individual technical teams “doing their own thing”. Rather we think in terms of the overall goal which should be directed to the main goals of the organization .

ITIL emphasises that IT should be seen as a service to the business.
ITIL could be (part of) a Quality Management strategy to improve the quality of the IT Service for the business.
Introducing clear processes should enable the company to grow and/or bring on more staff more easily.
Being based on a “best practice” approach means that you do not have to reinvent the wheel.
Cost reduction - Standardising “how you do things” can simplify and reduce costs.
Professionalism / Clear points of contact with external organisations and stakeholders.

Is ITIL a panacea for all IT Infrastructure Management challenges?
It never claims to be !
It is a set of good practice processes to be used as a “toolkit”
ITIL itself speaks about:
Process / Product / People.
Implement ITIL as part of a Strategic Cultural change in the organisation, which should include:
Metrics, Operational Tools, Processes, Standards.
Can you implement “parts” of ITIL and ignore the rest?
Remember that to make processes succeed you need appropriate data.
