ITIL v3: What It Is and Why You Should Care
Author: Hank Marquis
Abstract
The Information Technology Infrastructure Library (ITIL) is the
proven way for IT organizations to align with the business, control
costs, improve quality, and balance resource allocations. Research
shows a dramatic increase in ITIL adoption over the last few years.
A study in 2006 showed that about 30% of IT organizations were
using ITIL; a 2008 follow-up survey puts the count at 80%. This
white paper describes ITIL's benefits and history, as well as why
you need to know about it, which types of IT organization can
benefit from using it, and how to get started.
IT as a Strategic Resource
ITIL v3 is a collection of five primary volumes, or books. It is
quite literally a library of best practices focused on managing IT
organizations and the services these organizations produce and
deliver. ITIL is now in its third generation, with the most recent
edition (v3) released in May 2007.
ITIL describes how to manage IT as a business in order to
deliver competitive advantage to the enterprise. Its guidance spans
all IT activities from strategy to operations. The purpose of this
comprehensive guidance is to deliver on four primary goals:
- Align IT activities and projects to business requirements
- Control IT costs
- Improve IT service quality
- Balance resource allocations
These are lofty goals, but ITIL has the experience to deliver.
ITIL started in the late 1980s when the British Central Computer
and Telecommunication Agency (CCTA), now called the Office of
Government Commerce (OGC), made a decision to improve its IT
management systems. The CCTA commissioned a study group to develop
a new approach to managing IT. From this group came the ITIL
version 1. ITIL v1, while similar in objective, was significantly
different from today's version. This difference is what makes ITIL
so powerful - since it is based on best practice, it is under
continuous improvement from a worldwide community. ITIL adapts to
meet the needs of IT as IT matures, making ITIL always relevant and
useful.
The primary global organization driving the content of the ITIL
is the IT Service Management Forum, itSMF (http://www.itsmf.net) an
IT industry consortium dedicated to managing the cost and quality
of IT service management. Members comprise IT organizations of all
types, including government, military, profit, and not-forprofit.
The itSMF counts many hardware, software, and services companies as
members as well. Altogether the diverse members of the itSMF make
up over 500 local chapters around the world.
Collectively, itSMF USA is the US branch of the international
organization, and it represents those with a stake in IT service
management. The itSMF is involved in two areas. First, the
organization provides a forum to address technical and business
issues that will enhance the benefits of IT management applications
and services. Second, it educates the market about IT service
management and its value-in effect, marketing IT service
management.
Because ITIL had its start in the British government, ITIL
adoption began there; it then quickly spread to nongovernment
organizations within Britain. From Britain, ITIL moved to Europe
and Canada, where it has seen heavy adoption. From Canada, ITIL
finally made its way to the United States. The adoption of ITIL, by
both government and non-government organizations within the US, is
gaining momentum.
Vendors & Organizations That Have Adopted ITIL
Hewlett-Packard, Microsoft, IBM, CA, BMC, and many others have
used ITIL as a base for their own proprietary IT management frame
works. Many of the chapters in the ITIL volumes were written by
individuals from these companies, and some have created tools that
align with ITIL:
- Microsoft offers Microsoft Operations Framework (MOF)
- HP offers IT Service Management Reference Model
- IBM offers IT Process Model
The adoption of ITIL is gaining momentum in the US. This is
evident in the fact that as more of the IT tools have added the tag
line "ITIL compliant" into their advertisements. The following list
highlights just a few notable organizations which have publicly
commented on their ITIL implementation, and its contribution to
business success.

What Makes ITIL Different?
Over the years, many of you have probably been involved in
projects and/or exposed to theories related to IT improvement such
as:
Project Management (www.pmi.org)
COBIT (www.isaca.org)
Balanced Scorecards (www.balancedscorecard.org)
Six Sigma (www.isixsigma.com)
ISO-9000 (www.iso.org)
TQM / Deming (www.deming.org)
Capability Maturity Model (www.sei.cmu.edu)
All of these programs provide methodologies that can be used to
improve the processes that you have in place. However, these
methodologies provide little or no guidance about which processes
are required for IT to function well. The ITIL framework is a
source of good practice in service management. ITIL provides a
guide to the framework of processes required to run IT as a
Business for the Business and the relationship between those
processes.
ITIL v3 offers much more than the process-centric model
presented in ITIL v2. ITIL v3 presents a lifecycle approach to
managing IT services designed to provide the most value possible to
the business. By focusing on the services IT provides to the
business in support of the business or mission of the enterprise,
the IT organization can know how best to apply all the previously
described quality, project, process, governance, and security
models and frameworks.
IT organizations worldwide use the ITIL to establish and improve
capabilities in service management. ITIL has the following
components:
- The ITIL core consists of five volumes of good practice
guidance applicable to all types of organizations to provide
services to a business
- The ITIL complementary guidance is a related set of
publications with guidance specific to industry sectors,
organization types, operating models, and technology
architectures
The five ITIL volumes define a lifecycle of service management
activities. Each stage of the lifecycle has interfaces to the
processes and functions of the other phases. The Service Portfolio
represents all the resources and capabilities (and services) of the
service provider; the Service Catalog is a listing of the services
available to IT and the business. The ITIL volumes each relate back
to the Service Catalog, Service Portfolio, and creating value for
the business. The following table lists the ITIL v3 publications
and brief descriptions.

It is possible to adopt ITIL while still using any of the
process improvement methodologies listed above. It is not a case of
using one or the other.
What Is the Expected ROI?
The widespread adoption of ITIL within an industry will provide
guides to what works and what doesn’t.
Implementation of ITIL can be costly, and even more so when done
poorly and not according to a focused plan. So where can an
organization expect to recover those costs?
Here is a partial list the benefits:
- Key focus on services and providing value to the business in
the form of enhancing the utility (functionality) and warranty
(ability to perform as required) of IT services
- A common dictionary, an item that has been lacking in the IT
world
- Strong guidance for managing suppliers and choosing suppliers
based on their contribution to the utility and warranty (value) IT
services offer to the business
- Improved financial management of IT and a better matching of IT
services to the needs of the overall organization with a focus on
transparency and enhanced decision-making
- Improved relationship between IT and the organization for which
it provide services – generally called business IT alignment
- Improved utilization of the IT infrastructure through a more
holistic understanding of the purpose and function of IT assets at
all levels
- Improved utilization of IT personnel by setting the stage for
automation, and standardizing service offerings, as well as
creating a shared service model
- Improved reputation of IT within the organization that
naturally occurs with a focus on business outcomes and creating
value
Most people with a lot of ITIL experience state that adoption of
ITIL has no end point, only a starting point and milestones along
the way to measure your level of continuing success.
What Are Some of the Difficulties of ITIL Implementation?
The adoption of ITIL may not be easy, or short, or cheap. One
reason is that IT has not often run itself like a business. IT has
a habit of operating as an indispensable group that can use
resources and provide services as it sees fit. How many times have
you heard the phase, “We know what our customer needs, and that is
what we are providing”?
IT has not run itself based on documented needs of the business.
One place where this is clearly evident is that many organizations
lack a strong change management process. In these organizations,
systems change frequently and have an adverse effect on the
productivity of the entire organization. Most IT outages are the
direct result of a well-meaning IT worker not having sufficient
knowledge of or information about the systems on which they are
working. Unknown to the IT worker, a simple-appearing modification,
update, change, etc.
can result in disastrous consequences for the business. ITIL v3,
with its focus on lifecycle and service as primary generators of
value to the business, offers excellent guidance with regard to
managing knowledge.
The ITIL framework is about process, not organization. Most IT
organizations have spent years dividing up IT resources into towers
of responsibility, hardware, software, and staff. Breaking down or
redefining these towers to expedite the processes within the ITIL
framework and making sure that the necessary information is passed
between processes may be the biggest and most difficult challenge.
Because this is such a large stum-bling block, it should be
understood that the requirement for ITIL adoption must come from
the very top of the IT organization.
The implementation of ITIL cannot be accomplished in six months.
But most IT projects are expected to show major positive results or
even be completed within six months. ITIL will not meet either of
those milestones. ITIL milestones are measured in years rather than
months. However, with a carefully focused plan, it is possible to
achieve some results quickly – often in a matter of weeks. Still,
“full ITIL” can take years. It is important to know, however, that
not everyone needs or can even expect to implement all of the
guidance contained within the ITIL. Rather, the proven path to
success is to adopt just those bits of the ITIL that have
significant impact on the specific organization.
Implementing ITIL may also require new resources. An
organization’s present technology may not be able to support the
processes or inter-process communication required by ITIL. Even
though the ITIL framework is about processes, that framework can
only work efficiently when the right tools to support both the
processes and the inter-process data exchange are in place. For all
but the smallest IT organizations, some form of automation or
software tool is a requirement.
Another difficulty is determining where to start. Two questions
often asked are:
- Do we try to do everything at once?
- It is such a major undertaking, where do we start?
The answer to the first question is “no.” Trying to do everything
at once is too difficult and will only increase the chance of
failure. The answer to the second question depends on each
individual organization.
ITIL provides flexibility in approach, offering a specific
methodology for establishing a service strategy:
Define IT services. A service cannot be managed unless what
comprises it is known. This is the fundamental and primary first
step.
Value the IT services. With the service is
defined, establishing the relative value of each service to the
business is next. Focusing on the most important IT services first
is the only way to deliver significant and measurable value to the
business in a reasonable timeframe.
Measure IT services. Once service is defined
and valued, and precedence set, then the quality of service
provided to customers can be measured. Starting with the most
valuable service, measure the service to see if it meets
requirements. If the service does not meet requirements, this is
the starting point.
Commission projects for improvement. Following
the first three steps identifies what to focus on. With this
information, one can now examine the ITIL (and its complementary
guidance) to understand precisely what is not occurring that
results in the service quality issue at hand and apply the guidance
to this specific problem.
Even though ITIL implementation can be difficult, the true value
is the long-term adoption of best practices that have shown a
positive return on investment. ITIL builds a stronger organization
that matches the service provided to the present and future needs
of the business and provides that service in a cost-effective
manner.
Both of these actions will improve the standing of IT within the
business and improve both the competitive advantage and bottom line
of the business.
What Are the Steps To Getting Started?
For most organizations, education or training is the first step.
ITIL brings with it a common dictionary of IT terminology, as well
as many tools and techniques that must be learned since most IT
organizations operate without them today (and generate the problems
most IT organizations today face).
Many companies begin by requiring most or all of their IT staff to
take a 2–3-day ITIL Foundations Certification class. Many companies
require that the class include a certification test at the end.
This training provides a common understanding of the ITIL
framework, the value of the service lifecycle approach, how and
where IT can add value to the business, and a common language for a
more accurate discussion during the implementation.
A second step is to designate someone to manager the ITIL
adoption project, the adoption of ITIL is a major project that
requires formal oversight. The project manager should be an ITIL
Certified Service Manager or have at least one advisor who is so
certified. This is a long-term project, and every effort should be
made to have the same Certified Service Manager for the duration to
provide continuity to the ITIL implementation.
The IT Services Manager is the person who should carry out the
four steps of service strategy. Executing the four service strategy
steps will produce an inherently justified plan articulated in
business terms. Engaging with the business helps steer IT and
insures that the focus is on those systems and applications that
can have the most positive contribution to the business of the
business.
An ongoing step is to consider is the need for new technology.
However, new technology should not be considered until processes
are defined. It is important to remember that technology is only an
enabler and does not improve weak processes. The selection of a
tool for software system should be the last step in a well-executed
plan based on ITIL.
