Leveraging the ITIL Service
Support Framework — Increase Efficiency in IT Operations
and Support (Part 1)

Part I: The first in a two-part series, this article
discusses key reasons for inadequate service desk performance and
how to address these shortcomings through three best practice IT
Service Management disciplines: Change Management, Configuration
Management, and Release Management.
Introduction
Service desks exist to resolve end user computing incidents. But
in many cases, the front-line service desk acts as little more
than an answering service, logging incidents and forwarding them
to a more senior IT person for resolution. Further, service desks
often lack the information needed to address end-user incidents – particularly
those that involve proprietary applications. The under-utilization
of front-line service desks poses both cost and credibility problems
for IT organizations. Incident resolution costs (and indirect
opportunity costs) increase as cases are passed on to more senior
IT specialists. Business users suffer from productivity declines
and perceptions of IT often sour as customers fail to see their
issues being addressed in a timely fashion. One approach in addressing
these challenges is the implementation of integrated Service
Management processes that enable the IT organization to better
integrate and manage change and the flow of information between
groups and disciplines within IT.
The Problem
Service desks typically function as the primary point of contact
between IT and the end user community. Despite this critical
role as IT ambassadors, front-line service desks often are ill-equipped
to handle many technical issues beyond the most basic desktop
and networking functions such as permissions and password resets.
Service desk team members generally possess only a basic understanding
of the IT infrastructure’s components (network components and desktops)
and their interrelationships. Further, service desks are often not informed
of planned changes to the environment. Instead, front-line service desks tend
to focus more on answering the phone quickly, ensuring good customer service
skills, and resolving basic and “known” incidents and service requests.
Organizations with this orientation generally exhibit the following
conditions:
- A lack of shared tools and information across IT disciplines
- A lack of effective knowledge transfer from various teams
and disciplines within the IT organization to the front-line service
desk
- Poorly adhered to, or nonexistent, processes governing IT
operations
In configurations where the front-line service desk is
underutilized, there exists the opportunity to significantly enhance
the desk’s
value by increasing its ability to resolve a larger and broader
set of issues. This in turn will help contribute to reduced incident
resolution costs and help to support good relations between IT
and the business.
The Solution
To enhance the capacity of the service desk to provide sustained
higher end incident resolution, changes across the entire IT operation
are required. This can be done by instituting integrated IT Service
Management best practices that will:
- Significantly enhance the efficiency and reliability of IT
systems and infrastructure
- Provide substantial resources to the front-line service desk
to provide informed high-quality support to end users that will reduce
the flow of cases to more expensive IT resources
One of the leading
best practice frameworks in the provision of IT Service Management is the Information
Technology Infrastructure Library, popularly known as ITIL. ITIL was developed
in the 1980s when the British government determined that IT service quality
provided by both internal and external resources was inadequate
to its needs. Bodies within the government, in partnership with
various contractors, developed the standards to be general enough
to apply to public and private sector organizations of varied
size and industry and with all sorts of unique needs and challenges.
Today, thousands of organizations use all or some of the ITIL
standards to provide a framework to manage the provision of IT
services.
Three sub disciplines (or modules) of the ITIL best practice
framework directly address key functions within the IT operation
that have a direct impact on the quality of service delivered
by the front-line service desk. They are:
- Configuration Management
- Change Management
- Release Management
Configuration Management
In the ITIL framework, Configuration Management is a discipline
that organizations use to gain and maintain control and proper
oversight of their IT infrastructure in order to deliver high-quality,
consistent, and economical services to their organization.
This is done by creating a comprehensive model of the IT infrastructure
and its asset components, particularly focusing on the relationships
between assets. In practice, Configuration Management involves
the maintenance of a Configuration Management Database (CMDB),
which contains details of the current state of all elements
of the IT infrastructure and their relationships to one another.
Change Management
Change Management is a structured process and approach toward
making changes to the IT infrastructure. It is designed to gather
suggested changes from multiple constituencies, and to ensure
that changes are authorized, prioritized on an enterprise basis,
and that all impacts have been recognized and considered, thus
reducing the potential for support incidents in the user community.
Release
Management
Release Management is an ITIL discipline that uses a series
of prescribed procedures and checks to ensure that any changed
or new elements slated for release into the IT infrastructure do
not negatively impact the live environment or its users.
Release Management involves building a set of release components,
testing them, assessing potential impacts, scheduling the release,
and performing the release.
In next week’s issue of SSPA News, we will discuss how these
disciplines relate and benefit Service Desk performance, as well
as factors to consider before implementing a best practice regimen. |
