Service

• In order to understand what service management

is, and why it is so important to enterprises, we

need to understand what services are, and how

service management can help service providers to

deliver and manage these services.

• ITIL defines a service as follows:

SERVICE A service is a means of delivering value to customers by facilitating outcomes that customers want to achieve without the ownership of specific costs and risks.

What is an IT Service?

An "IT Service" is a set of IT-related functions (HW & SW)

User Web Server Application Server Database Server

Service management

• Service management is what enables a service

provider to:

• understand the services that they are providing from

both a consumer and provider perspective;

• ensure that the services really do facilitate the

outcomes that their customers want to achieve;

• understand the value of those services to their

customers and hence their relative importance;

• understand and manage all of the costs and risks

associated with providing those services.

Service management

• These ‘specialized organizational capabilities’ include the

processes, activities, functions and roles that a service

provider uses in delivering services to their customers, as

well as the ability to establish suitable organization

structures, manage knowledge, and understand how to

facilitate outcomes that create value.

ITIL • Developed in late 1980s in the UK in response to growing

dependence on IT

• Now a public body of knowledge for Service Management

best practices

• Helps organizations improve service levels and reduce the

cost of IT operations

• A framework, defining ten interlocking processes for service

support and service delivery

• Also provides guidance on IT security, business management

• The ten ITIL processes are described in two volumes:

• Service Support focuses on management of essential operational

processes

• Service Delivery on strategic management of the IT services

What is a function?

• A function is a subdivision of an organization that is

specialized in fulfilling a specified type of work, and is

responsible for specific end results. Functions are

independent subdivisions with capabilities and resources

that are required for their performance and results. They

have their own practices and their own knowledge body.

What is a process?

• A process is a structured set of activities designed to

accomplish a defined objective. Processes result in a goal-

oriented change, and utilize feedback for self-enhancing and

self-corrective actions.

• Processes possess the following characteristics:

• They are measurable - because they are performance-oriented.

• They have specific results.

• They provide results to customers or stakeholders.

• They respond to a specific event - a process is indeed continual

and iterative, but is always originating from a certain event.

It can be difficult to determine whether something is a function

or a process. According to ITIL, whether it is a function or

process depends completely on the organizational design. A

good example of a function is a service desk, a good example

of a process is change management.

What ITIL is not?

A complete blue-print, but bricks and material from which you can build your own building depending on your needs. A blueprint is a reproduction of a technical drawing, documenting an architecture

or an engineering design, using a contact print process on light-sensitive sheets.

A quick fix, but a set of processes that you have to build into the

mind-set of your employees, and which must be continually updated and improved.

Something you buy, although you can buy help to implement it, the core of the work is changing your own organization and how it thinks and functions.

Another method of control, but a way of setting up your organizaton so that it works towards the goals without controlling management.

“ Think of ITIL not as a destination, but as a vehicle you can use to help you travel more quickly and efficiently on your ongoing journey of continuously improving service levels”

THE ITIL FRAMEWORK

• ITIL is not a standard in the formal sense but a framework which is

a source of good practice in service management. The standard for

IT service management (ITSM) is ISO/IEC 20000, which is aligned

with, but not dependent on, ITIL.

• As a formal standard, ISO/IEC 20000 defines a set of requirements

against which an organisation can be independently audited and, if

they satisfy those requirements, can be certificated to that effect.

The requirements focus on what must be achieved rather than

how that is done. ITIL provides guidance about how different

aspects of the solution can be developed.

The ITIL Library has the

following components:

• The ITIL Library has the following components:

• ITIL Core: Publications describing generic best practice that is

applicable to all types of organization that provide services to a

business.

• ITIL Complementary Guidance: A set of publications with

guidance specific to industry sectors, organization types, operating

models and technology architectures.

THE ITIL CORE

• The service lifecycle is an approach to IT service

management that emphasizes the importance of

coordination and control across the various functions,

processes and systems necessary to manage the full

lifecycle of IT services.

• The service management lifecycle approach considers the

strategy, design, transition, operation and continual

improvement of IT services.

• The service lifecycle is described in a set of five

publications within the ITIL Core set.

THE ITIL CORE

• Each of these publications covers a stage of the service

lifecycle (see below figure) from the initial definition and

analysis of business requirements in service strategy (SS)

and service design (SD), through migration into the live

environment within service transition (ST), to live

operation and improvement in service operation (SO) and

continual service improvement (CSI).

COMPLEMENTARY

MATERIAL

• Although the material in the core is likely to remain fairly

constant, complementary material is likely to be more

dynamic. Complementary material may take the form of

books or web-based material and may be sourced from the

wider industry, rather than from The Cabinet Office/The

Stationery Office (TSO).

• Examples of such material are glossary of terms, process

models, process templates, role descriptions, case studies,

targeted overviews and study aids for passing

examinations. These will typically be officially

commissioned and published by TSO.

RELATED MATERIAL

• Apart from the ISO/IEC 20000 standard, ITIL is also

complementary to many other standards, frameworks and

approaches. No one of these items will provide everything

that an enterprise will wish to use in developing and

managing their business. The secret is to draw on them for

their insight and guidance as appropriate. Among the many

such complementary approaches are:

• Figure 1.3 illustrates how the service lifecycle is initiated

from a change in requirements at the business level. These

new or changed requirements are identified and agreed at

the service strategy stage and documented. Each of these

‘packages’ will have an associated defined set of business

outcomes.

• The package is passed to the service design stage where a

service solution is produced, defining everything necessary

to take this service through the remaining stages of the

lifecycle. Solutions may be developed internally or consist

of bought-in components that are integrated internally.

• The design definition is passed to the service transition

stage, where the service is built, evaluated, tested and

validated, and transitioned into the live environment,

where it enters the live service operation stage. The

transition phase is also responsible for supporting the

service in its early life and the phasing out of any services

that are no longer required.

• Service operation focuses on providing effective and

efficient operational services to deliver the required

business outcomes and value to the customer. This is

where any value is actually delivered and measured.

• Continual service improvement identifies opportunities for

improvement (which may arise anywhere within any of the

lifecycle stages) based on measurement and reporting of

the efficiency, effectiveness, cost-effectiveness and

compliance of the services themselves, the technology that

is in use and the service management processes used to

manage these components. Although the measurements

are taken during the operational phase, improvements may

be identified for any phase of the lifecycle.
