Service Life Cycle
8
Why Service Management ???
• Technical Organizations spend much of their time with the following activities:– Recovering from failures (“incidents”) – Modifying or replacing technology
components to improve their reliability or functionality by eliminating issues (“problems” and “errors”) associated with those components
– Carrying out additions, modifications or removals (“changes”)
9
Service Management – Why ???
• This is where SM comes in. An SM approach to Technical management facilitates tighter Technical/customer alignment by providing Technological and its customers with the ability to:– Define Technical deliverables in terms of Services,
expressed in the customers’ and users’ language– Define how those Services will be delivered to the
users, in terms of functionality, availability, capacity, security, support, disaster recovery, change management and other dimensions of managing the service
– Understand the business impact when an Service fails– Prioritize Technical activities based on that impact
10
Service Management – Why ???
11
Service Life Cycle
• ITIL is the best practices of IT solution and the body of knowledge representing how organizations are dealing with the challenges of managing IT.
• ITIL processes are grouped into five stages of the service lifecycle:– Service Strategy ( SS )– Service Design ( SD )– Service Transition ( ST ) – Service Operation ( SO ) – Continual Service Improvement ( CSI ).
12
ITIL
13
Service Strategy

22
Service Design Processes
• Service Catalogue ManagementTo ensure that a Service Catalogue is produced and maintained, containing accurate information on all operational services and those being prepared to be run operationally.
23
Service Design Processes
• Service Level ManagementTo negotiate Service Level Agreements with the customers and to design services in accordance with the agreed service level targets.– SLA– OLA– UC– SLR– SAC
24
Service Design Processes

Service Design Processes
31
Service Transition
• To build and deploy IT services and makes sure that changes to services and Service Management processes are carried out in a coordinated way.
32
Service Transition
• Change ManagementTo control the lifecycle of all Changes through enable beneficial Changes to be made, with minimum disruption to IT services.• Change EvaluationTo assess major Changes, before those Changes are allowed to proceed to the next phase in their lifecycle.
33
Service Transition Processes
• Project Management (Transition Planning and Support)
To plan and coordinate the resources to deploy a major Release within the predicted cost, time and quality estimates.• Application DevelopmentTo make available applications and systems which provide the required functionality for IT services.
34
Service Transition Processes

Benefits of using ITIL
• ITIL is proven and used worldwide• Improved customer satisfaction and
relationships• Better reliability and quality of service• Optimization of service delivery across
the supply chain– Reduce support costs by 30%– Increase incidents fixed at first call by 20%– Increased value from service portfolio, with reduced cost and
risk
• Competitive advantage through value creation and agile change

Resistance to ITIL Improvement
Initiatives
• No management commitment• ITIL is the objective not what it should
achieve • Plan, Do, Stop......No continual
improvement focus• IT thinks it doesn't need to understand
the business to make a business case • Unable to specify the VALUE required by
the business• Everything has the highest priority
