ITIL –
Service
Delivery
Processes

Financial Management
• The discipline of ensuring the IT infrastructure is obtained at
the most effective price
– Not necessarily the cheapest!
• IT Costs can be divided into different units:
– Equipment
– Software
– Organization (staff, overtime, etc.)
– Transfer (costs of 3rd party service providers)
• Calculating the costs of providing the service so the
organization can justify the costs of its IT services
– Costs can then be recovered from the customer of the service
– Costs can also be divided into direct and indirect costs, and can be
capital costs or ongoing costs.

SLAs should be SMART
SMART means that goals must be …
•Specific - defined unambiguously
•Measurable - be measurable (who/what when,
what/how much, how often)
•Appropriate - be achievable (e.g. with regards to
resources)
•Relevant - must provide a required and effective
service (i.e. add value)
•Timetabled - must be mapped to time limits
13
Question: What should be included
in an SLA?
• Provide a list of SLA contents
• 5 minutes

Service Level Management
• Provides a way to align the IT services with the business
requirements.
• Customers and IT personnel can discuss and asses how well a
service is being delivered.
– Primary Objective: Provide a way for setting clear expectations with
both customers and user groups
– Service Level Management is dependent upon all the other areas of
service delivery
• Business processes associated with SLM:
– Reviewing existing services
– Negotiating with the customers
– Implementation of Service Improvement policies and processes
– Planning for service growth
– Involvement in accounting to asses costs of services
17
Service Catalogue & SLAs
• Service Catalogue
– Documents IT Services
– Transparent to customers
• SLAs
– Specification of Service Characteristics
– Defines and determines mutual responsibilities
– Can be based on a given SLA template

OLA, UC & SLA
19
(Buchsein, 2008: 126)
SLA, OLA & UC
• Service Level Agreements (SLAs):
– Communicate and document the agreed-upon expectations of business-facing
IT services.
– Are agreed upon between business and IT representatives.
• Operating Level Agreements (OLAs):
– Communicate and document the agreed-upon expectations of dependent IT
services.
– Are agreed upon between IT teams.
• Underpinning Contract (UC):
– Ensures there is a contract between suppliers, third parties, and the
organization.
– Communicates and documents the agreed-upon expectations between the
suppliers, third parties, and the organization.

20
OLA, UC & SLA
• SLA
– ISO 20000 „… a written agreement between a service provider and a customer
that documents services and agreed service levels“ (i.e. a collection of
promises)
– ITIL und ISO20000 contain recommendations for the creation of SLAs
regarding typical contents, structure, reporting and measurement
– CobiT: Refers to SLAs when defining Control Objectives and Performance
Indicators. No requirements regarding contents of SLAs
• OLA (Operational Level Agreement): An Agreement between an IT Service
Provider and another part of the same organization. An OLA supports the
IT Service provider's delivery of IT Services to Customers. The OLA defines
the goods or Services to be provided and the responsibilities of both
parties.
• UC (Underpinning Contract): Contract with external suppliers
→ Sum of agreed OLAs and UCs secure SLAs

SLA Metrics (Examples)
• Uptime Agreements: Common agreements include percentage of system /
network uptime, power uptime, amount of scheduled maintenance
windows etc.
• Performance Agreements: Performance (eg speed, response time,
turnaround time of system)
• ABA (Abandon Rate): Percentage of calls abandoned while waiting to be
answered.
• ASA (Average Speed to Answer): Average time (usually in seconds) it takes
for a call to be answered by the service desk.
• TSF (Time Service Factor): Percentage of calls answered within a definite
timeframe, e.g. 80% in 20 seconds.
• FCR (First Call Resolution): Percentage of incoming calls that can be
resolved without the use of a callback, or without having the caller call
back the helpdesk to finish resolving the case.
• TAT (Turn Around Time): Time taken to complete a certain task. 31
Service Level Management
• Provides a way to align the IT services with the business
requirements.
• Customers and IT personnel can discuss and asses how well a
service is being delivered.
– Primary Objective: Provide a way for setting clear expectations with
both customers and user groups
– Service Level Management is dependent upon all the other areas of
service delivery
• Business processes associated with SLM:
– Reviewing existing services
– Negotiating with the customers
– Implementation of Service Improvement policies and processes
– Planning for service growth
– Involvement in accounting to asses costs of services
33
Capacity Management
• Includes planning, sizing, and controlling service solution
capacity to satisfy user demands.
• This requires a collection of information about usage
scenarios and patterns as well as stated performance
requirements
• Inputs:
– Performance monitoring
– Workload monitoring
– Application sizing
– Resource forecasting
– Demand forecasting
– Modeling
34
IT Service Continuity Management
• Also known as contingency management
– Focuses on minimizing the disruptions to businesses caused by failure of “mission-
critical” systems
– Deals with planning to cope with and recover from an IT disaster
– Also considers what activities need to be taken in the event certain services are not
available
– often overlooked until it is too late!
• Basic steps:
– Prioritizing the businesses to be recovered by conducting a Business Impact
Analysis (BIA)
– Performing a Risk Assessment (Risk Analysis) for each of the IT Services to identify
the assets, threats, vulnerabilities and countermeasures for each service.
– Evaluating the options for recovery
– Producing the Contingency/Recovery Plan
– Testing, reviewing, and revising the plan on a regular basis
35
Availability Management
• Main goal is to ensure the IT services are available to users when they need them.
• Availability is usually calculated and reported as a percentage of the agreed service
hours for which the service was available.
• Calculating availability:
– Serviceability – when a service is provided by a 3rd party, this is the expected availability of
those components
– Reliability – how long a component can be expected to perform under certain conditions
without failing
– Recoverability – how long it should take to restore a component back to its normal state after
a failure
• Measuring availability:
– Agreement statistics – what is included within the agreed service
– Availability – agreed service times, response times
– Help Desk Calls – number of incidents raised, response times, resolution times
– Capacity – performance timings for online transactions, report production, numbers of users, etc.
– Costing Details – charges for the service, and any penalties should service levels not be met.

Discussion
• Which KPIs are essential for the provision of
Service Level Management, Capacity
Management, Availability Management,IT
Service Continuity Management?
• Which are the most relevant KPIs for each
process?

ITILv3 & Sourcing
• Internal Customer – Service Provider
• Outtasking: Services delivered through a Service Provider
(external) under the control and guidance of (internal) IT
• Partial Outsourcing: Provision of concrete IT-Services (i.e. IT-
Service are sourced from (external) Service Provider. IT uses
/combines these with other (internal & external) services and
keeps overall IT control
• „Full“ IT-Outsourcing
– Entire IT is outsourced to a Service Provider
– IT is merely a Sourcing-Unit

Service Support – Service Desk
• Service Support revolves service (or help) desk
– Centralised and/or “Virtual”
– Permissions of helpdesk
– Levels of expertise & training
• Unskilled (used for incident tracking and call dispatching)
• Skilled (incidents are solved at the helpdesk)
– Lines of communication; Transition of Incidents to Problems
• Questions / Issues:
– Customer needs and business needs are understood.
– The service desk is an integral part of any organization, an effective
service desk with strong communication can lower costs throughout
the organization.
• The #1 call received by a helpdesk is to help reset/restore a password
• Provide alternate means to reset passwords, and other common helpdesk
functions.

Service Support – Service Desk
• Service Support revolves largely around a strong service or help desk.
– Centralised and/or “Virtual”
52
What is Service Operation?
• Business as usual, Day-to-day
• “Factory” of IT
• Synthesis of Service and Infrastructure
• Execution of all processes and services
• Operational validation
53
Why Service Operation?
• Stability but not stagnation
• Realizing value of IT
• Responding to operational needs in Business and
Technology
• Great design is worth little if it can not be
delivered
• Great work is worth little if it is not appreciated

Service Support – Event, Incident and
Problem Management
• Event: A change of state which has significance for the
management of a Configuration Item or IT Service (or alert or
notification created by any IT Service, Configuration Item or
Monitoring tool….events often lead to Incidents being logged)
• Incident: Any event which is not part of the standard operation of a
service and which causes, or may cause, an interruption to the
quality of that service.
• Problem: A problem is the result of multiple incidents that results in
a RFC or Known Error instead of a fix.
• Goals:
– Restore systems as quickly as possible with minimal impact to the business.
– Ensure that the integrity, confidentiality, and availability of IT services are
maximized throughout the organization.

Jan van Bon. IT Service Management – An Introduction. itSMF International / Van Haren Publishing. 2007.
Service Support – Change Management
• If Change Management procedures are not effective, this may
result in unauthorized changes to IT Services, which could
have major impacts on the business even collapse of the
business that the IT Services are there to support.
• Goal
– Ensure that standardized methods and procedures are used for
handling of changes.
– Sarbanes-Oxley makes this more important than ever!
• Path:
– RFC’s should go through multiple checks and must pass some final
decision making point, CAB or manager.
– All RFC’s should be subjected to a routine scrutiny.
– Good project management

Question:
– How do we reduce incidents and keep the organization aware
of known errors?
– How can we resolve RFC’s as quickly as possible?
• Trend analysis, incident classification, and a healthy flow of
information are all needed for good management.

SWOT Analysis
• A strategic planning method
– Evaluation of Strengths, Weaknesses, Opportunities, and Threats involved in a project or in a
business venture.
– It involves specifying the objective of the business venture or project and identifying the
internal and external factors that are favorable and unfavorable to achieve that objective.
– The technique is credited to Albert Humphrey, who led a convention at Stanford University in
the 1960s and 1970s using data from Fortune 500 companies.
• A SWOT analysis must first start with defining a desired end state or objective. A
SWOT analysis may be incorporated into the strategic planning model. Strategic
Planning has been the subject of much research.[citation needed]
• SWOT
– Strengths: characteristics of the business or team that give it an advantage over others in the
industry.
– Weaknesses: are characteristics that place the firm at a disadvantage relative to others.
– Opportunities: external chances to make greater sales or profits in the environment.
– Threats: external elements in the environment that could cause trouble for the business.
