This article answers frequently asked questions about the IT Infrastructure Library (ITIL), as an aid to CIOs considering implementing ITIL in their organizations.
ITIL is a Service Management framework.
What is Service Management? The ITIL publication, Planning to Implement Service Management defines IT Service Management (ITSM) as "management of services to meet the customers' requirement," where services are "the deliverables of the IT services organization as perceived by the Customers; the services do not consist merely of making computer resources available for customers to use."
I have found it useful to define ITSM as follows: "Managing IT as a services business, where resources are deployed and managed to a discrete set of defined services, and where the quality of those services as perceived by the customer is the #1 driving and aligning force in the organization, with quality being defined as 'matched to user and business needs as they evolve.'"
In a nutshell, ITSM is about organizing and managing the IT function around services with discrete value propositions, rather than just technology or customers/business units.
What is ITIL?
ITIL is a set of publications that provide descriptive (what to do and why) guidance on IT service management. Created in the late 1980s by a UK government agency and later expanded for use in all organizations, ITIL has become the international de facto standard for service management. Four features make ITIL unique:
- Vendor-neutral, best practice guidance. ITIL is a synthesis of ideas drawn from international IT practitioners—not academic theory of how things should be or a vendor's view of how to operate their products.
- Non-proprietary. While the ITIL publications aren't free, anyone can apply ITIL concepts freely in their organization.
- Comprehensive and consistent. Rather than providing isolated advice, ITIL attempts to describe every key process in IT service management and to use consistent, common sense definitions and distinctions across each process.
- Widely adopted, encouraging industry alignment and making it a defensible choice for how to organize the business of IT.
- Service Desk Function
- Incident Management
- Problem Management
- Change Management
- Configuration Management
- Release Management
- Availability Management
- Capacity Management
- Financial Management
- Service Level Management
- IT Service Continuity Management
Anyone implementing ITIL should have these books, along with the Security Management publication, as Service Delivery refers to but does not include this content.
Although Service Support and Service Delivery receive the majority of attention, there are additional ITIL publications, including:
- The Business Perspective: Business continuity management, partnerships and outsourcing, surviving change and business transformation
- ICT Infrastructure Management: Network service, operations, systems, and local processor management, and computer installation and acceptance
- Applications Management: Software development lifecycle
- Planning to Implement Service Management: ITIL benefits, how to achieve them
- itSMF ITIL Pocket Guide: presents the Service Support and Service Delivery content in capsule form and is a popular reference in the ITIL community.
- IT Service Management, an Introduction is a handy reference as well, as it summarizes all current ITIL titles.
Questions you have may include, What can I gain by adopting ITIL in my organization? What will ITIL do for me? What can I accomplish with ITIL?
Benefits derived from ITIL implementation include increased:
- Competitive advantage through cost reduction and by enabling growth and agility by the flexibility and scalability inherent in standardized processes and service organization
- Business efficiency through streamlining of IT processes and better alignment between vital business functions and IT services
- IT value through business and IT operational and goal alignment
- Improved internal customer and user satisfaction
- Speed and completeness of compliance with regulatory authorities, through a defensible standard model on which control objectives can be built
Chief among these benefits is alignment. Imagine if all of your suppliers, partners, and internal staff had a common sense of purpose, processes, and terminology. You'd then have a fighting chance of aligning all those moving parts. That's the promise of IT service management—alignment—and with the increasing worldwide adoption of IT service management, that alignment promises to extend outside your organization to your entire value chain, including your customers, users, suppliers, tool vendors, outsource providers, and prospective employees.
You can expect to derive the benefits listed above by properly implementing ITIL. The operative term is "properly"; while ITIL may be common sense, many find making it common practice in an organization difficult.
What are other organizations doing with ITIL?
Over 10,000 organizations worldwide have adopted ITIL. Organizations that have published case studies claiming significant benefits from ITIL include Proctor & Gamble, Capital One, Boeing, British Petroleum, the US Army, US Navy, and the IRS.
According to a 2003 itSMF survey* and a 2002 survey by DMR**, organizations implementing ITIL saw the following benefits:
Improved customer satisfaction*
Motivated staff and increased productivity*
More consistently implemented changes**
Reduced amount of time spent "firefighting"**
Reduced repetitive problems**
Produced more business-focused metrics**
According to the 2002 study conducted by the itSMF [ServiceTalk, The Journal of the itSMF, Issue No. 53, February 2002], 97 percent of organizations using ITIL said they had derived benefits from ITIL with 69 percent claiming tangible and measurable results. Procter & Gamble claims a 6 percent reduction in operating costs in one department as a result of an ITIL initiative and expects similar savings as adoption spreads throughout the company.
