Service Level Management Financial Management for IT services Capacity Management IT Service Continuity Management Availability Management
GOALS GOALS GOALS GOALS GOALS
To maintain and gradually improve IT service quality
trough a constant cycle of agreeing monitoring and
reporting upon IT service achievement and
instigation of actions to eradicate poor service
To provide cost-effective stewardship of the IT assets
and resources used in providing IT Services
To ensure that cost-justifiable IT capacity always
exist and that it is matched to the current and future
identified business needs
or
Having the appropriate IT capacity and making best
use of it
The goal for ITSCM is to support the overall
Business Continuity Management process by
ensuring that the required IT technical and services
facilities can be recovered within required, and
agreed, business timescales
Satisfy Business objectives
Achieve sustained level of availability
Ensure cost effectiveness
Optimize the capability of services and components
OBJECTIVES OBJECTIVES OBJECTIVES OBJECTIVES OBJECTIVES
High quality, cost effective, value-adding IT services
that underpin the organization’s business needs
Play a key role in ascertaining the business
requirements
SLA is written agreement between the customer and
the IT service provider, defining key targets and
responsibilities on both sides
To manage the financial aspects of IT assets and
resources cost-effectively
To account fully for the total spend on the provision
of IT Services and to attribute the cost to the services
delivered
To advise management on IT investment matters by
providing detailed business cases

in conjunction with ITSCM determining the vital business
functions and impact arising from IT component failure
defining the targets for Availability, reliability and
maintainability for the IT Infrastructure components

and Maintainability that reflects the business, User and IT
support organisation perspectives

and Maintainability of IT components
reviewing IT Service and component Availability and
identifying unacceptable levels
investigating the underlying reasons for unacceptable
Availability
producing and maintaining an Availability Plan which prioritises
and plans IT Availability improvements.
DEFS DEFS INPUTS Recovery Types INPUTS
Service Catalog: defines services with default levels
and options. Gives a profile of IT service provider to
org. and overview of services provided to users.
SLR-Service Level Requirements: list of clients reqs.
OLA-Operational Level Agreements: Between 2
intern IT departments
UC-Underpinning Contract: With an external
supplier.
SLA
SIP-Service Improvement Program: SLM with PM
and AM starts a formal project focusing on user
satisfaction
Cost Model: by service, location, customer (for
charging)
Cost Types: HW, SW, People, Accommodation,
External services, Transfer costs
Cost Elements: Sub elements of Cost Types, like HW =
NW, Server, Office

Do nothing - Few, if any, organisations can function
effectively without IT Services. Even if there is a
requirement for stand-alone PC processing, there is
still a need for recovery to be supported.
Manual Work-arounds - manual Work-arounds can
be an effective interim measure until the IT Service is
resumed wherever they are practical and possible.
Reciprocal arrangements - Entering into an
agreement with another organisation using similar
technology. Benefits can exist, in maintaining some
reciprocal arrangements, for example, in the off-site
storage of backups and other critical information.
Gradual Recovery (cold standby) - up to 72 hours,
without a re-establishment of full IT facilities.
Accommodation fully equipped with power and local
network cabling Infrastructure, telecom connections.
Fixed or portable facility.
When opting for a gradual recovery, consideration
must be given to highly customised items of
hardware or equipment that will be difficult, if not
impossible, to replace.
Intermediate Recovery (warm standby) 24 to 72 hour
period. It is usually far away (logistics) and shared
with 20 to 30 other companies. Use 6-12 weeks. Can
be portable, in a trailer.
Immediate Recovery (hot standby) provides for
immediate restoration. Application systems and
communications already available and data mirrored
from the operational servers. In the event of a system
failure, the Customers can immediately switch to the
backup facility with little or no loss of service.
System can be used as backup and reporting resource.

Competitive advantage
A single point of accountability for availability is established
within the organization
IT Services are designed to meet the IT Availability
requirements of the business
the levels of IT Availability provided are cost justified
the levels of Availability required are agreed, measured and
monitored to fully support Service Level Management
shortfalls in the provision of the required levels of Availability
are recognised and appropriate corrective actions identified and
implemented
a business and User perspective of IT Service Availability is
taken to ensure optimal usage and performance of the IT
Infrastructure is achieved to deliver maximum benefit
the frequency and duration of IT Service failures is reduced
over time
IT support organisation mindset moves from error correction to
service enhancement; from reactive to proactive attitude
the IT support organisation is seen to 'add value' to the
business.
PROBLEMS PROBLEMS PROBLEMS Contingency Plan PROBLEMS
ensuring targets are achievable (use existing
achievements if known)
verifying targets prior to agreement (prior
monitoring, pilot SLAs)
Monitoring of actual achievement (only agree what
can be monitored)
Inadequate resources and time (process must be
properly staffed and resourced
Lack of understanding (educations)
Differences in perceptions within the customer
community (need to agree relevant targets at all
levels)
Not enough seniority (give Service Level Manager
the appropriate authority)
SLA may not be supported by adequate underpinning
agreements/contracts (review OLAs and contracts)
Lack of understanding leading to inefficient, overlay
expensive or over-complex systems
Monitoring tools inaccurate or too expensive
Delay in obtaining, or inaccurate, information
Difficulty in recruiting staff with accountancy and IT
skills
Unable to respond to changes quickly enough
Lack of management understanding and support
Unrealistic expectations
Vendor influence
Lack of accurate information
- business data
- technical data
Distributed environments
Level of monitoring to be implemented
IT infrastructure, comprising the replacement system,
plus contracts/agreements necessary for recovery
IT Infrastructure Management and operating
agreements/procedures during a disaster
Personnel - details of those needed at contingency
site plus accommodation required
Security instructions, emergency contacts and items
for home site
Contingency site: location, people, facilities, security
and transport arrangements
Return to normal - dependencies affecting the return
Defining availability levels that are meaningful to the business
Managing internal and external providers is made difficult by
lack of agreed availability targets
Assessing achievable and cost-effective levels of IT service
availability
New services are implemented without full consideration of
availability requirements
Loss of business and reputation due to unstable IT services
Lack of accountability
