ITIL® v3 Foundation Study Guide

 Good practices are best practices which have gained
wide acceptance and adoption.
 In short, Good Practices have withstood the test of
time.
 Good Practices may come from a number of sources
including:
 Standards
 Public frameworks
 Academic research
 Proprietary knowledge
 The Service Lifecycle

 Services
 Services are a means of delivering value to customers
without requiring the customer to own specific costs
and risks.
 Service Management
 Service Management is a set of specialized capabilities
for delivering value to customers in the form of services.
 ITIL® is a framework for IT Service Management.

 The core of ITIL® is structured
around a Service Lifecycle
which consists of the five
phases
 The Service Lifecycle
organizes activity around
services as the services move
from concept through the live
environment and into
retirement.
 The ITIL® ‘core’
documentation consists of
five volumes representing
each of the phases of the
Service Lifecycle.

 Processes are structured sets of activities designed to
achieve a specific objective.
 Processes have four basic characteristics:
 They transform inputs into outputs
 They deliver results to a specific customer or
stakeholder
 They are measurable
 They are triggered by specific events
 ITIL® addresses a number of specific processes
associated with each lifecycle phase.

 Processes generic structure
shown in the three-layered
model below.
 Process Control, such as
process policies, ownership,
documentation, review
programs, etc.
 The Process itself including
process steps, procedures,
work instructions, roles,
triggers, metrics, inputs, and
outputs.
 Process Enablers such as
resources and capabilities
required to support the
process.

 Functions are self-contained subsets of an organization intended
to accomplish specific tasks.
 They usually take the form of a team or group of people and the
tools they use.
 Whereas:
 processes help organizations accomplish specific objectives--often
across multiple functional groups—
 functions add structure and stability to organizations.
 Functions generally map fairly directly to the organizational
chart of an organization and are usually supported by budgets
and reporting structures.
 Processes, by contract, typically do not have budgets and
reporting structures.
 Both functions and processes involve roles.

 Roles are defined collections of specific responsibilities and
privileges.
 Roles may be held by individuals or teams.
 Individuals and teams may hold more than one role.
 ITIL® emphasizes a number of standard roles include, most
importantly:
 Service Owner -- Accountable for the overall design, performance,
integration, improvement, and management of a single service.
 Process Owner -- Accountable for the overall design, performance,
integration, improvement, and management of a single process.
 Service Manager -- Accountable for the development, performance,
and improvement of all services in the environment.
 Product Manager – Accountable for development, performance,
and improvement of a group of related services.

 ITIL® discusses a number of recommendations for how
IT Service Management organizations can best be
structured.
 Most of this discussion focuses on four major
functions (Service Desk, Technical Management,
Application Management, and IT Operations
Management).

 Service Desk:
 Provides a single point of contact between users and the IT organization.
 Processes inbound incidents, service requests, change requests, etc.
 Also acts as a hub for all communications internal to the IT Service Provider.
 It usually (but not always) owns and executes the Incident Management
process.
 Four basic Service Desk configurations are discussed within ITIL®:
 Local – Users and support staff are located on the same premises or campus.
 Centralized -- Multiple user locations are serviced by a single support location.
 Virtual -- Multiple user location are serviced by multiple support locations
which by virtue of call routing and other technology are able to appear and
respond to user requests as a single entity.
 Follow-the-Sun -- Identical to a virtual Service Desk, but organized in such a
way as to utilize support staff shifts working during normal daylight hours for
all user requests coming from any time zone.

 The Technical Management function is charged with
procurement, development, and management of the
technical skill sets and resources required to support
the infrastructure and the IT Service Management
effort.
 Technical Management is typically divided into
specialty areas representing different specialized
teams or functions within an IT organization, e.g.
Networking, Security, Database, Storage, Servers, etc.
 The primary objective of Technical Management is to
ensure that the Service Provider has the right skill sets
available to deliver the services it offers.

 Application Management is concerned with the end-
to-end management of applications in the
environment.
 Like Technical Management, a big part of what it does
involves cultivation of the specialized skill sets
required to support the organization’s applications.
 Application Management does not replace, but rather
executes and is supported by core processes such as
Incident Management, Problem Management, Change
Management, Availability Management, etc.

 IT Operations Management is concerned with the day-to-day maintenance of
the IT infrastructure and the facilities which house it. It is divided into two
sub-functions: Operations Control and Facilities Management.
 Operations Control
 The Operations Control sub-function is concerned with regular maintenance
cycles associated with infrastructure management.
 These include such activities as:
 Console Management
 Backup and restore operations
 Media management
 Batch job execution
 Facilities Management
 Facilities Management is concerned with maintenance of the facilities which
house IT operations, e.g. data centers, call centers, development facilities, etc.
 Its areas of responsibility include things like:
 HVAC
 Fire suppression
 Facilities access
 Power

 In addition to discussing the four primary functions described above,
ITIL also utilizes the RACI model as a generic tool for reviewing and
assigning four key roles to any important task or activity.
 Whereas role assignments are often well-defined within functions, the
RACI model holds particular value for ensuring that roles are
appropriately filled or covered within processes.
 Those in the R = RESPONSIBLE role for a given activity are charged
with actually executing or performing the activity or task.
 The single entity in the A = ACCOUNTABLE role owns the task or
activity and must answer for its outcomes. Only one party can be
accountable for a given task/activity.
 Those in the C = CONSULTED role review and provide advice and
authorization around the task or activity.
 Those in the I = INFORMED role receive updates as the task or activity
progresses.
 Note that all rows have one and only one ACCOUNTABLE and at least
one RESPONSIBLE.
