The Service Desk
The Service Desk
Goals
To
act as the single point of contact between the User and IT
Service Management and track status of all customer interactions
To
handle Incidents and requests, and provide an interface for other
activities such as Change, Problem, Configuration, Release, Service
Level, and IT Service Continuity Management
Inputs to the Service Desk
Information
The Service Desk
Why a Service Desk?
Essentials
• The Service Desk is more than just a Help Desk
• The first and single point of contact
• High quality support to meet business goals
• Help identify costs of IT services
• Proactive support and communication of changes
• Increase user perception and satisfaction
• Identification of business opportunities
• Identification of Training Opportunities
The Service Desk
Responsibilities
The Service Desk
Activities
• Receive and record all calls from users
• Provide first-line support (using knowledge resources)
• Refer to second-line support where necessary
• Monitoring and escalation of incidents
• Keep users informed on status and progress
• Provide interface between ITSM disciplines
• Produce measurements and metrics
Incident Management
Incident Management
Goals
To restore normal service operation as quickly as possible with
minimum disruption to the business, thus ensuring that the
best achievable levels of availability and service are
maintained
Incident definition
Any event which is not part of the standard operation of a
service and which causes, or may cause, an interruption to, or
a reduction in, the quality of that service
Work-around definition
A method of avoiding an Incident or Problem either by
employing a temporary fix or technique so the user is no
longer reliant on a Configuration Item (CI) that is known to
cause failure
Incident Management
The Incident Life Cycle – the monitoring and
tracking of Incidents
Activities
Including Impact and Urgency
selection
Yes
No
Note. This is not Problem Closure
Categorization
Incident Management
Activities
•Service affected (and possibly by association the
affected SLA)
•User perception of failure in terms of the User’s
inability to do something
–Batch job output has not been received
–I can’t print, connect to a server or access an
application
•Category and details of CI thought to be at fault
•Category and details of CI eventually found to be
at fault
•The fault in the CI, the quick fix and the action
taken, etc.
Impact, Urgency & Priority
Incident Management
Definitions
Impact
Urgency
Priority
A measure of the business criticality of an
incident or problem (e.g. numbers
affected, magnitude)
A measure of the speed with which an
incident or problem requires resolution
(i.e. how much delay will the resolution
bear)
The order in which an incident or
problem needs to be resolved, based on
impact and urgency
Incident Management
Illustrative Example
Payroll Application: System run once per month to run payroll
Failure of payroll
server
Impact
Urgency
Priority
High: will effect all
employees
Low : Payroll not run
for 3 weeks
Low (at the
moment)
High: will effect all
employees
High : Fix needed

Incident Management
Escalation
Definitions
Hierarchical escalation would typically include authorization,
resources and/or cost
Hierarchical (authority)
Functional (competence)
Functional escalation might include specialist groups e.g. Unix Group
Functional Escalation
Incident Management
Activities
The use of support
teams is important
in efficient incident
resolution.
• First line support
deals with the
communication to
the user, resolution
of known incidents
(e.g. password
resets)…
• …allowing the
second and
subsequent levels
to focus on
resolving assigned
incidents.
Problem Management
Problem Management
Goals
To minimize the adverse effect on the business of Incidents and
Problems caused by errors in the infrastructure, and to
proactively prevent the occurrence of Incidents, Problems and
Errors.
Problem definition
Unknown cause of one or more incidents
Known Error definition
An Incident or Problem for which the root cause is
known and for which a temporary work around or
permanent alternative has been identified
Problem Flow

IT Management
Configueration Management
Configuration Management
Definitions
• Configuration Item (CI) – a component of an IT infrastructure
which is (or is to be) under the control of Configuration
Management and therefore subject to formal change control
• Configuration Management Database (CMDB) – a database
which contains details of the attributes and history of each CI and
the relationships between CIs
• Baseline – a snapshot of the state of a CI and its components or
related CIs, frozen in time for a particular purpose, such as:
– The ability to return a service to a trusted state if a change goes
wrong
– A specification for copying the CI or for a roll-out
– The minimum CIs needed to maintain vital Business Functions
after a disaster

Change Management
Change Management
Goals
Process of controlling changes to the infrastructure or any
other aspect of services, in a controlled manner, enabling
approved changes with minimum disruption.

Change Management ensures that standardized methods and
procedures are used for the efficient and prompt handling of all
Changes, in order to minimize the adverse impact of any
Change-related incidents upon service quality.

Changes can arise as a result of Problems, Known Errors and their
resolution, but many Changes can come from proactively seeking
business benefits such as reducing costs or improving services
Change Management
Change Management
Definitions
•Change – a deliberate action that alters the
form, fit or function of Configuration Item (CI)
such as an addition, modification, movement, or
deletion that impacts the IT infrastructure
•Request for Change (RFC) – a means of
proposing a change to any component of an IT
infrastructure or any aspect of an IT service
•Forward Schedule of Change (FSC) – a
schedule that contains details of all the changes
approved for implementation and their proposed
implementation date
Change Management
Change Management
Definitions
•Standard Change – a Change that is recurrent,
has been proceduralized to follow a pre-defined,
relatively risk free path and where Change
Management and budgetary authority is
effectively give in advance
•Service Request – a request, usually made
through a Service Desk, for a Standard Change
–Example: providing access to services for a new
member of staff or relocating a few PCs
Release Management
Release Management
Goals
Release Management takes a holistic view of a Change to an
IT service and should ensure that all aspects of a Release, both
technical and non-technical, are considered together
• Good resource planning and management are
essential to package and distribute a Release
successfully.
• The focus of Release Management is the
protection of the live environment and its services
through the use of formal procedures and checks.

ISO 20000
•What Is It?
•How Does It Relate To ITIL?
ISO 20000: Basic Concepts
• Quality standard for IT Service Management
Formal specification defined requirements for an organization
to deliver managed services to acceptable quality to customers
• BS 15000 fast-tracked to become IS0 20000
• ITIL forms the basis of the standard
• Standard = a list of criteria that needs to be met
The standard versus the framework
• Standard = audit & certify against. Makes ITIL alive
• Framework = best practice that the standard is based on

Example: Change Management
Specifications: Objective + Requirements
Objective:
To ensure all changes are assessed, approved, implemented and
reviewed in a controlled manner
Requirement examples:
• All requests for change shall be recorded and classified, e.g.
urgent, emergency, major, minor
• Requests for changes shall be assessed for their risk, impact
and business benefit
• All changes shall be reviewed for success and any actions
taken after implementation
Example: Change Management
Code of Practice: Objective + Detailed Best Practices
Objective (Sub-process: 8.2.2): Closing and reviewing the
change request
Detailed Best Practice:
• All changes should be reviewed for success or failure after
implementation and any improvements recorded
• A post-implementation review should be undertaken for major
changes to check that:
– a) the change met its objectives;
– b) the customers are happy with the results;
– c) there have been no unexpected side effects
• Any nonconformity should be recorded and actioned
• Any weaknesses or deficiencies identified in a review of the
change control process should be fed in to service
improvement plans
