EVOLUTION OF ITIL
 ITIL - Information Technology Infrastructure Library
 History
Originally created in late 80s by the UK government
Now truly global and applicable to all IT Services
Focus on process and roles rather than organisation
Version 1 in 1991- focused on UK Government
Version 2 in 2000 - Industry wide and took into account changes in
technology
 Version 3 in June 2007 – Life Cycle Approach

ITIL …
 Is a collection of books which contain
recommendations & suggestions to improve
provision of IT Services
 Not a standard but a Best Practices Framework
 Needs to be adopted and/or adapted
Benefits of ITIL framework: increased user and customer satisfaction with IT
services
 improved service availability, directly leading to
increased business profits and revenue
 financial savings from reduced rework, lost time,
improved resource management and usage
 improved time to market for new products and
services
 improved decision making and optimized risk.

1. SERVICE STRATEGY
ACTIVITIES OF SERVICE STRATEGY
 Identify market & define your target area
 Decide what services you want to offer & who can be
the potential customers
 Develop your service offerings
 Build on/improve your services
 Develop strategic assets
 Develop new services
 Help clarify the relationships between different services,
processes, strategies etc.
SERVICE STRATEGY
 1.Demand Management
 2.Service Portfolio Management
 3.Financial Management
SERVICE STRATEGY 1 OF 3
DEMAND MANAGEMENT
Simply Speaking
Demand Management = Know your customer and
then identify his / her requirements
BASIC CONCEPTS OF SERVICE STRATEGY
 Utility – It is derived from the attributes of service which have
a positive effect on the performance
 What does the service do?
 Functional requirements
 Features, inputs, outputs
 Fit for purpose
 Warranty – It is derived from positive effect being available
when needed, in sufficient capacity & magnitude &
dependably in terms of Continuity & Security
 How well service does it
 Fit for use
OBJECTIVES
 To understand customer’s current requirements
 Trend of requirements over a period/business cycle
 Match the customer’s expectations with organization's
capabilities of providing services
 Ensure Warranty & Utility are in alignment with customer’s
needs
KEY CONCEPTS
• Core service vs. Supporting Service
• Pattern of Business Activity (PBA), User profile
• Service Package (SP) vs. Service Level Package (SLP)
• Business Relationship Management
Core Service vs Supporting Service
 Core Service is the service which actually brings ‘value’ to the
customer.
 It’s a service which is KEY from organization's perspective as well
 E.g. for a Banking customer, the core services provided will be all
financial services
 Supporting Service ‘supports’ or enhances the core services
 It’s like an added feature which may not be desired but
important to have
 Many times it becomes necessity
 E.g. supporting services in above case could be providing a
helpdesk which helps/troubleshoots any issues/queries faced by
users when they access the website
Pattern of Business Activity (PBA) & User Profile
 Represents change in pattern of customers demands as
explained by organization
 Important to track as it helps organization identify
improvements in existing services or identify future
opportunities
 Also important to study customer’s business & changing
business needs
 User Profile
 Demand patterns shown by users
 Users means people or even processes/functions etc.
 Is usually associated with/is subset of PBA
SP vs SLP
 Service Package is a bundle of core services and/or
supporting services which is offered to customer
 SP Includes Service Level Package
 SLP has a defined level of Utility & Warranty for a
given SP
 E.g. Buying 100 servers is a SP deal but some of
them could be under Gold/Silver SLP
Business Relationship Management

 Implementation of changes
 Any other task documented as out of scope
Change Types
• Standard Changes
• Routine Changes that follow an established procedure
& do not disrupt It services
• E.g. updating the Anti-Virus software is a standard
Change
• Emergency Changes
◦ Crucial to an organization and have to be implemented
immediately.
◦ Emergency Changes are disruptive and prone to failure
◦ E.g. the some ports in critical switch has gone down.
Therefore, a new switch needs to be installed
• Request for Change (RFCs)
• Incidents, upgrades to the infrastructure, or changes
in the business requirements generate the need for a
Request for Change (RFC)
• Change Classification & Prioritization
• To classify & plan changes in the order of their impact
& urgency
• Change Models
◦ Predefined way or procedure for handling known type
or complexity
◦ Automated as far as possible
◦ Allow for scalability to create a new model
• Forward Schedule of Changes (FSC)
• Contains details of all approved changes and their
implementation dates for an agreed period
• Detailed short term schedules and less detailed for
longer term planning
• Projected Service Availability (PSA)
• To
determine the best time for a change
implementation
• Both the FSC and PSA are agreed with the customers
• Back Out Plan
• It is executed if the Change can not happen as per plan
• Usually but not necessarily the typical back out plan is
to bring the systems back to original state it was in
before the change started
 Change Advisory Board (CAB)
 CAB approves Changes after assessing and prioritizing the RFCs.
 CAB members should have sound technical knowledge and
good business perspective.

RELEASE & DEPLOYMENT MANAGEMENT
Simply Speaking
R & D Management = Bring in the change Carefully
OBJECTIVES
 Implementing the authorized changes as per
Change plan
 Plan, Design, Build, Test & Install Hardware &
Software components
 Skills & Knowledge Transfer to enable
 Customers & users the optimum use of service
 Operations & support staff to run & support the
service
KEY CONCEPTS
 Release
 Release Units
 Release Identification
 Types of Release
 Release Methods
Release
 A collection of authorized Changes to an IT Service
 A Release is defined by the RFCs that it implements
 A Release could consist of a number of Problem fixes
and enhancements to a service.
Release Units
• A Release unit describes the portion of the IT infrastructure
that should be released together.
• Depending on the type or item of software and hardware, the
size of the unit can vary. An example of hardware Release
Unit can be changes to the complete PC or Processor. An
example of a s/w release unit could be changes made to a
system, suite, program or module.
• Including too many changes in one release can be too
complex for safe implementation while too many releases
affect user dependency on the stability of the service.
Release Identification
• The status of a Release alters according to its current
environment.
Release
identification
means
determining the status of a Release in different
environments. The environments in which a Release
can be categorized are:
–
–
–
–
Development
Test
Live
Archive
•
Release Types
Depending on the number of changes that should be included in one Release, a
Release can be of the following type:
 Delta Release
 Just a few changes normally a quick fix
 Package Release
 You use a Package Release when you Release a group of software.
Each of the software in the package depends on the other software in
the group for its performance.
 For example, scheduled upgrades to third-party software, such as
Systems software and Office applications are appropriate for Package
Releases.
 Full Release
 When a program is released in its entirety, including the parts that
were not changed.
 A number of similar Changes can be implemented together in this
Release
 More preparation and resources are required for a Full Release
