Overview of IT Service Managment Using the IT Infrastructure
Library (ITIL)
Author: Hank Marquis,
Ph.D., FBCS CITP
This white paper introduces managers with an interest in
information technology to the ITIL. You will become familiar with
ITIL processes and understand where ITIL fits within your
organization. You will be able to identify the benefits available
from ITIL and craft a high-level business case for ITIL adoption in
your organization. This paper first describes the context for ITIL,
what it is, and how it works, and then describes the benefits
others have found from ITIL adoption. Along the way, you'll be
exposed to the issues faced by IT managers and their business
units, realize how IT commoditization offers an opportunity to
excel, and learn how to achieve strategic benefit through
operational excellence.
Brief History of ITIL v3
The ITIL (IT Infrastructure Library) is a collection of books.
The current version, version 3, consists of five volumes. This
version of ITIL was released in 2007. The previous version, version
2, consisted of seven volumes and was released in 2001. Earlier
versions of ITIL can be traced back to the late 1980s.
Regardless of the version, the ITIL consistently presents an
evolving and integrated approach to managing IT services. The
concept of managing by service is relatively simple-in order for
the IT service provider to add value to its enterprise and its
consumers, the IT provider must focus on end-to-end service
delivery. This requires the provider to understand the marketplace
within which the consumers of its services operate. From a normal
corporate or enterprise perspective, this means the IT department
must understand not only its business customers and users, but also
the marketplace within which the enterprise offers its products. IT
value arises at the boundaries between the enterprise and its
marketplace. IT services provide an indirect value-the IT service
facilitates the interaction of business customers and users with
enterprise end-customers and end-users.
The reasons for ITIL adoption are many; however, the primary
driver is IT commoditization. IT commoditization refers to the fact
that businesses today are more and more dependent upon IT services.
As the cost for hardware and software falls, the ease with which it
may be interconnected is increasing dramatically. This presents
business with many alternatives to the traditional IT organization.
Many businesses simply acquire and install systems on their own
that were traditionally the purview of an IT organization. In many
organizations, such ad hoc business IT systems are then connected
to traditional business IT systems. The result is an incredibly
complicated environment that shows no signs of decreasing in
complexity.
While business not only assumes the mantle of IT provider in
many cases, the requirements business places upon the IT
organization and technology in general is also increasing. Referred
to as variability, the issue is that as a business becomes more
entwined with information technology services, it can sustain less
and less variation in the quality and delivery of those
services.
For the IT organization, this combination of factors represents
an "IT perfect storm." Simply put, today's IT manager faces
ever-growing complexity with diminishing tolerance for poor
quality. This, combined with economic realities such as decreasing
IT budgets and headcounts, represent a no-win situation-not just
for the business but also for the IT organization.
From this vantage point, ITIL begins to describe how the well
functioning IT service provider aligns with its business,
understands its marketplace, and balances its resources in ways to
best benefit the business. For these reasons, the ITIL has become
the global de facto best practice for managing IT operations
worldwide. ITIL is also supported with an international standard
called ISO/IEC 20000, or ISO20K. The combination of the two
provides virtually everything an IT manager requires to align with
business, control the costs of IT, improve IT service quality, and
balance resource allocations.
Since the business does not operate independently of the IT
systems or the IT organization, it is equally important for
technical and non-technical managers to understand how they must
work together. The ITIL provides such a roadmap.
The State of IT Today
One cannot overstate the criticality of ITIL at this very
important juncture in history. There is a tremendous disconnection
between the consumers (that is, business customers and users) and
the providers (that is, the IT organization) of IT services. Recent
surveys continue to show a substantial gulf between the two.
Surveys taken in 2008/2009 have shown the following viewpoint from
business customers and users regarding IT services:
- 21 percent of organizations view IT as an "expensive
overhead"
- 45 percent view IT as "necessary"
- Only 32 percent see IT as a "valued strategic partner"
- 37 percent feel that "business is constrained by IT"
- Another 14 percent said, "IT is not considered part of business
advancement"
This represents a fairly disconcerting reality. However, it is
not without merit. Other surveys show that the IT organization in
most situations to be fairly dysfunctional:
- 60¢ of every $1 spent on IT goes toward infrastructure
- Less than 20 percent manage
human capital or worker performance
- 8 out of 10 IT outages are caused by a failed change
- 70 percent of support calls are
“self-inflicted”
- Only about 20 percent of all IT projects are successful
- 30 percent are cancelled at significant loss, balance
not as promised
- 25 percent of hardware and software is never installed
- 67 percent of IT organizations don’t track software
assets
- 90 percent of mid-market IT organizations use manual
processes
- Most IT organizations average 6 standalone IT
software tools that do not interoperate with each other
The purpose of this paper is not to disparage the hard-working
and dedicated staff found in most IT organizations. Nor is the
purpose of this paper to call into question the decision making
capability of the businesses funding these IT organizations.
However, there is clearly a substantial miscommunication and
misunderstanding occurring in today’s IT organizations.
The purpose of ITIL is to present one solution to bridging this
gap. ITIL requires the IT organization to work hand in glove with
its business to understand business needs. Conversely, it is
incumbent upon the business organization to engage with the IT
organization in order to properly guide, steer, and fund IT
activities. Many business organizations feel that outsourcing is a
solution to these issues. It is not. Outsourcing simply moves the
entire IT organization or bits and pieces of the IT organization to
other providers. Core issues remain. ITIL works equally well for IT
service providers supporting a business unit, IT service providers
supporting an entire enterprise, or IT service providers that are
outsourcers.
Moving from Good to Great in the Pursuit of Competitive
Advantage: ITSM to BSM
IT Service Management (ITSM) is the term used to describe
managing the workflow and activities within an IT organization. The
ITIL is the worldwide de facto ITSM solution. BSM (Business Service
Management) is the term used to describe the strategic direction
required for ITSM to be successful. Both BSM and ITSM are on the
continuum ranging from managing IT resources through managing
applications to managing workflow to managing towards business
outcomes.
Technology Management
Technology management is usually the first phase of a maturing
IT organization. Managing technology usually involves technology
silos and organizational autonomy and bias based around the
resources required to manage a particular type of technology (for
example, networking or software development.) Technology management
is focused on technology. It is generally represented with
fragmented management views due to its disconnected and
technologist nature. This produces an emphasis on resolving IT
technical issues. It can also result in redundant investments. The
value of investments made in information technology at this
technology management stage is generally minimally visible to the
business and mostly visible to the IT organization.
Application Management
Application management is generally the natural evolution of the
IT organization from a technology point of view to an application
point of view. From this perspective, the maturing IT provider
begins to consider the fact that it provides applications to its
business customers and users. These applications in turn provide
value to the enterprise. Application management is an evolution of
technology management—slightly more encompassing application silos
replace individual technology silos and organizations. Generally,
these application silos span several technology silos and even some
IT organizational boundaries. Management design focuses on the
requirements of the application. This produces a limited
integration of management views, and the IT emphasis is on
resolving application issues. The primary value of information
technology investments at this phase is visible to the business
customers and users of the applications.
Business Management
Business management is a primary focus of the ITIL. The goal,
simply stated, is to manage IT investments in ways that matter most
to the success of the enterprise and its marketplace. Business
management is by IT service and business process. It spans all
technologies and all organizational boundaries. IT Service
Management, focusing on process integration and automation, leads
management and design. The primary emphasis of the IT organization
is on addressing service issues faced by the business. The value of
IT investments at this point becomes clear to the marketplace and
is seen by the enterprise as competitive advantage.
How the Structure of the ITIL Promotes Enterprise Success
ITIL presents a structure that describes all common IT
activities within the context of a lifecycle. The purpose of the
lifecycle metaphor is to make it easy to understand how the various
processes and functions described within the ITIL should be used.
As a structure, the ITIL has five core topics: Service Operation,
Continual Service Improvement, Service Strategy, Service Design,
and Service Transition. The purpose of these five competency areas
(each one supported by an ITIL volume) is to encapsulate IT Service
Management and make it approachable and its benefits
attainable.
Service Operation
Service Operation includes all of the activities required to
provide the ongoing management support for the IT organization and
the services it provides. Service Operation includes some
well-known IT activities (for example, the Service Desk, also known
as a Help Desk). Also included in Service Operation are Event,
Incident, Access, and Problem Management process definitions. This
is an excellent example of the ITIL lifecycle approach. Events
represent happenings within the infrastructure that are interesting
to the IT organization (for example, notifications from systems and
so forth). An event may result in an incident—where an incident is
defined as an unplanned interruption to an IT service. Access
Management considers topics such as rights management for customers
and users. Problem Management focuses on the resolution of failures
by removing the root cause. Together the
core processes spanning the management of the events through to
problem resolution represent a lifecycle. The value to the business
is a more proactive IT organization. Additionally, the business has
a constant source of communication and information about the
activities occurring within the IT organization. Providing a
central and singular point of contact for all IT services, Service
Operation improves business customer and user productivity
dramatically. The output of service operation from a lifecycle
perspective is service performance reports.
Continual Service Improvement
CSI (Continual Service Improvement) uses the operational metrics
produced by Service Operation to consider ways to improve the
efficiency, effectiveness, economy, or equity of IT service support
and delivery. Working with the business customers and users, IT
management translates operational metrics and observations into
proposals for improvement. CSI provides and collects input to and
from the business and feeds this information into service strategy.
This very important function results in a validation with business
customers and users about proposals from the IT organization.
Before any IT proposal begins consuming significant resources, it
is first vetted with the business. If it does not make business
sense, the improvement proposal terminates. This critical
evaluation prevents waste and can have a significant positive
contribution to the effectiveness of IT projectm management. It
also drives business-IT alignment and increases IT transparency.
From a lifecycle perspective, the output of CSI is referred to as a
SIP (Service Improvement Plan). The SIP moves to Service Strategy
for continued
definition.
Service Strategy
Service Strategy encapsulates all of the strategic thinking
required to analyze CSI proposals. It includes fundamental concepts
of Financial and Demand Management, as well as a focus on managing
business investments in IT as a portfolio. The concept of Service
Portfolio Management aligns very well with the balanced scorecard
approach often used in business. Service Strategy considers
important topics, such as return on investment. The purpose of
Service Strategy is to ensure that the IT organization spends its
limited resources in ways that provide the most value for the
enterprise. The output of Service Strategy is called an SLP
(Service Level Package) that includes the required functionality or
utility of the service, and the warranty required to ensure the
service meets business requirements.
Service Design
Service Design includes the review of existing capability in the
form of service catalogs, Service Level Agreements, and suppliers
in order to determine whether the new service as defined in the SLP
requires development or may be served by some combination of
existing assets. This is a very important and valuable technique
that prevents duplication of efforts and hence can reduce costs
substantially. Within Service Design, the SLP becomes an SDP
(Service Design Package). The SDP includes the specific capacity,
availability, continuity, and security requirements needed to meet
the utility and warranty specifications developed by CSI and
Service Strategy. The SDP also includes instructions for the
Service Transition team, which is responsible for transitioning the
newer
changed IT service into production and handing off control and
management to Service Operation.
ITIL Benefits
Examples of the success of the ITIL approach are many. Following
are just a few example comments and quotes from businesses choosing
to pursue ITIL:
- Centrica: “IT service delivery costs to fall
by $20 million a year”
- Oslo Stock Exchange: “100 percent uptime since
1999”
- DHL: “Core ITSM processes implemented in 11
months, achieved 20 percent cost reduction”
- Avaya: “Now we manage business services rather
than just IT elements: IT costs reduced by 30%”
- Roche: “Introduced a consistent global service
management process that meets validation requirements”
From an IT operations perspective, the benefits of ITIL
include:
- Reductions in complexity
- Effective management of IT assets
- Standardization of services and organization
- Prioritization of IT activities and projects
- Consolidation of duplicate process, technology, and
systems
- Optimization of IT spending and control costs
- Compliance with regulations and mandates
- Improved productivity of IT and business
- Enhancement in IT service quality
- Evolving of a service and team approach, managing of vendors,
and communicating with customers, between users, and between IT
departments
- Management of control and reporting
- Optimization of projects
- Increased agility
By focusing on the attainment of operational excellence within
the IT organization, and focusing on what matters most to the
business, the result is a win-win situation. The business excels in
its marketplace, and the IT organization becomes an integral and
valuable contributor to that success.
The combination of the ITIL lifecycle approach produces four key
benefits for the business and IT:
- Meets the changing demands of the business landscape
- Provides tangible evidence of alignment and value
- Moves IT beyond the image of a cost center
- Makes IT an innovator and business enabler
Well-formed IT Service Management initiatives in combination
with BSM concepts have allowed many enterprises to excel in their
marketplace. One of the most recent and notable is that of Liberty
Mutual Group, a North American insurance company. Within a 24-month
timeframe, LMG IT investigated issues of customer loyalty and
churn. Through ITSM and BSM, LMG realized that ongoing IT
maintenance activities traditionally done during “off hours” were
negatively affecting investors. On closer study, it turned out that
many investors preferred to manage their portfolio using LMG IT
services via the Web on weekends. LMG IT reorganized activities to
accommodate end-customers, dramatically improving satisfaction.
Over a short period of time, the results were remarkable: LMG
announced a $477 million quarterly revenue increase for Q2/2006. In
announcing this amazing increase, Chairman, President, and CEO
Edmund F. Kelly said on March 31, 2006: “I am pleased with our
financial results in the quarter; revenue growth reflects higher
retention of existing accounts and very satisfactory new business
growth.”
Clearly, the IT focus on the marketplace and end-customer
satisfaction instead of the more common technical orientation
resulted in resounding success for LMG and for consumers in its
marketplace.
Simplified Guide to Achieving Success with ITIL
Success with ITIL does not come overnight or without investment.
Perhaps the most important investment is that of
commitment—commitment from the business to work with IT, and
commitment from IT management to engage with the business and focus
on the marketplace.
It is possible to achieve visible and quick improvements in many
organizations. These are referred to as “quick
wins”—often-egregious situations that may be rectified swiftly
through a focused effort. Typically, quick wins from ITIL can be
realized within 6 to 9 weeks.
In all cases, the primary obstacle facing adoption and benefit
from ITIL is primarily resistance to change. Human beings in
general are loath to change how they have learned to do things.
Essentially, an effective ITIL implementation is an effective
change management program. The key to effective change management
from an organizational perspective is to focus on issues that
engage everyone, and to engage everyone on that issue.
Simply put, this means starting with strategy and not process or
technology. The successful ITIL implementation follows a very
specific recipe as described by the ITIL Service Strategy volume
and its Service Portfolio Management section, summarized below:
- Define services and validate business case (Service Catalog
Management)
- Analyze service value and prioritize to balance demand
(Financial and Demand Management)
- Measure quality (CSI, Service Level Management, Supplier
Management)
- Authorize and allocate resources (Configuration, Change, SLAs,
OLAs, and so forth)
Stage 1: Define Important IT Services in Business Terms
The basic concept is straightforward—to manage by service
requires the service be defined. This does not require complete
service articulation from enterprise product through to the last
bit of IT hardware or software, but rather an understanding of key
business processes, business customer and user constituencies, and
primary IT services supporting the same. These are referred to as
Customer Facing Services and represent those business applications
and services critical to the enterprise. They need not be
completely defined; however, they must be initially defined for the
IT organization to be able to value them.
Stage 2: Value IT Services Based on Risk to the Enterprise
IT service valuation is an important next step. With IT services
defined at a high level, it becomes critical to prioritize them
relative to each other. Given that IT services represent not only
benefit to the organization, but also liabilities and risks,
effective IT service valuation is essentially a risk management
exercise. Valuing IT services based on the risk they provide to the
enterprise provides an objective value achieved working with the
business.This value is used to rank services in terms of IT focus.
Generally speaking, at this point, the most important services will
now be known and agreed to by all.
Stage 3: Measure IT Service Quality and IT Organizational
Capability
Following definition and valuation, it becomes critical to
measure the quality of IT services. IT service quality cannot be
measured from within the IT organization. At best, internal
measurements of capacity, availability, and so forth can predict
what a user or customer may experience; however, true IT service
quality may only be measured subjectively based on customer
satisfaction. Measuring quality from external to the organization
indicates those services that are not performing as required. The
IT manager then turns his or her attention to understanding the
capability of the organization for that service. The product of
this measurement phase is a gap analysis indicating what is
required and what is being delivered. This gap, of course,
represents an improvement opportunity—an opportunity defined in
business terms, agreed with the business, and of the utmost
importance to the success of the enterprise.
Stage 4: Justify IT Service Improvement Projects in Business
Terms for Maximum Success
The final phase is the justification of the improvement project
in business terms. Every IT improvement program should be
instantiated as a formal project. This does not require significant
investment in overhead or infrastructure with regard to project
management, but rather a focus on a business case. The business
case, defined in business terms and with supporting
documentation from business stakeholders identified during the
definition and valuation and measurement phases, is critical. This
process ensures an easily understood document that describes in
business terms why the improvement is required and what will happen
if the improvement is not achieved. Having a defined beginning and
end along with specific goals and objectives, the business case
becomes a much stronger document than traditional IT proposals.
