What is IT Service Management (ITSM)?

• The management of IT services to support one or more business areas.

• ITSM is based on the IT Infrastructure Library (ITIL)

A standard set of published materials used worldwide

• The IT Infrastructure Library (ITIL) defines “best practice”processes.

Key objectives of Service Management

• Align IT services with the current and future needs of the business and its customers

• Improve the quality of IT services delivered

• Reduce the long-term costs of provisioning services

© 2007 Hewlett-Packard Development Company, L.P. 6

What is a Service?• Definition: “Work done for others as an occupation or

business” (American Heritage Dictionary)

• Historical Example: Roman Aqueducts

What is an IT Service?• A set of related functions provided by IT systems in support of

one or more business areas

• This service can be made up of hardware, software and communication components, but is perceived as a self-contained, coherent entity

Page 5: ITIL Foundations

What is a Service Culture?

• Recognition that the IT exists to further the business aims of the customers of its services.

• A willingness to go that ‘extra step’ to satisfy customer needs.

• An understanding of the customers’ perspective

• Achieving a Service Culture depends on:– Senior Management support– A good understanding of why IT Services are being provided– An understanding of the impact on the business of poor service– Clear targets to aim for, and from which to progress

© 2007 Hewlett-Packard Development Company, L.P. 10

The Four P’s

IT Service Management (ITSM) is all about the efficient, effective and economical use of:

• People– Customers, Users & IT Staff

• Processes– ITIL Service Support – “Operational”

Service Delivery – “Tactical”• Products

– Tools and Technology• Partners

– Vendors and Suppliers

Quality Improvement

• The customer is the most important part of the production line.

• It is not enough to have satisfied customers, the profit comes from returning customers and those who praise your product or service to friends and acquaintances.

• The key to quality is to reduce variance.

• Managers should learn to take responsibility and provide leadership.

• Improve constantly.

• Institute a vigorous program of education and self-improvement.

Dr. Edwin Deming

1900-1993

Quality Improvement – Deming Cycle

Quality management is the responsibility of everyone working in the organization providing the service.

Every employee has to be aware of how their contribution to the organization affects the quality of the work provided by their colleagues, and eventually the services provided by the organization as a whole.

Quality management also means continuously looking for opportunities to improve the organization and implementing quality improvement activities.

Plan – What needs to be done

Do – Planned activities are implemented

Check – Did the activities provided the expected result

Act – Adjust plans based on information gathered while checking

What is a Service Request?

A request from a user for support, delivery, information, advice or documentation, not being a failure in the IT infrastructure.

If a Service is requested that is not for a defined ‘standard service’, and it alters the state of the infrastructure, then it triggers a Request For Change (RFC).

An RFC is not handled by Incident Management but is dealt with formally by Change Management.

Definition — a Problem

“A problem is the unknown underlying cause of one or more incidents”

Problems are the responsibility of Problem Management

© 2007 Hewlett-Packard Development Company, L.P. 40

Definition — a Known Error“A known error is an incident or problem for which the root cause is known and for which a temporary workaround or permanent alternative has been identified.

It remains a known error unless it is permanently fixed by a change.”

Known Errors are the responsibility of Problem Management

EscalationIf an incident cannot be resolved by first-line support within the agreed time, then more expertise or authority will have to be involved.

• Functional Escalation (horizontal) - Functional escalation means involving personnel with more specialist skills, time or access privileges (technical authority) to solve the incident.

• Hierarchical Escalation (horizontal) - hierarchical escalation means involving a higher level of organizational authority, when it appears that the current level of authority is insufficient to ensure that the incident will be resolved in time and/or satisfactorily.

© 2007 Hewlett-Packard Development Company, L.P. 46

Critical Success Factors

Successful Incident Management requires:

• An up-to-date CMDB to help estimate the impact and urgency of incidents.

• A knowledge base, for example an up-to-date problem/known error database to assist with recognizingincidents, and what solutions and workarounds are available.

• An adequate automated system for recording, tracking and monitoring incidents.

• Close ties with Service Level Management to ensure appropriate priorities and resolution times.

IT Service Continuity

• A disaster is much more serious than an ‘Incident’. A disaster is a business interruption.

• That means that all or part of the business is not ‘in business’following a disaster.

• The IT Service Continuity Management process emphasizes prevention, i.e. avoiding disasters.

Service Continuity Strategy

• Which services will we plan for?

• What recovery and preventative options are available?

• What are the costs of each?

• Which services take priority in recovery?

Approaching Improvement with ITIL

“Greatness is largely a matter of conscious choice.”

Page 61: ITIL Foundations

Approaching Improvement with ITIL

Before we begin walking the roadmap:

• There must be a clear business justification for an ITSM implementation.

• Making business processes more efficient and effective is a justification example.

• All improvements must deliver benefits to the business, otherwise there is no business case.

• ITSM can make a difference to your entire organization.

© 2007 Hewlett-Packard Development Company, L.P. 122

ITSM Roadmap

• Successful deployments of IT Service Management follow the following path:

Learn

Evaluate

Align

Integrate

Page 62: ITIL Foundations

62

Step 1: Learn

• Senior management commitment– Resources– Budget

• Establishing a vision

• Training and communicating to employees about ITIL and the strategy for the organization

• Creating a sense of urgency

© 2007 Hewlett-Packard Development Company, L.P. 124

Step 2: Evaluate

• Evaluate what IT is doing today – IT Baseline

• Defining what are the “services” IT provides today?– Processes– Best Practices– Functions– Linkages

“All good to great companies begin their path to greatness by confronting the brutal facts of their current reality.”

Jim Collins – Good to Great

Page 63: ITIL Foundations

Step 2: Evaluate

• Identifying how large is the gap between the current role and the required role of IT:– Are the right processes and procedures in place

to achieve our goals?– Do we have the right skill sets in place for

success?– Do we have the right technology to support the

business?– Do we need to change how we work and act

within our culture? – How do we become more service oriented to

the business?

© 2007 Hewlett-Packard Development Company, L.P. 126

Step 3: Align

• Understanding the business, its stakeholders and its environment.

• Having the business understand what IT is capable of.

• Determine how IT impacts the business.

Page 64: ITIL Foundations

Step 4: Integrate

• Enact process changes in areas that make sense.

• Implement and change tools to support the processes…not the other way around.

• Eliminate services that have no value to the business.

• Recommend, prioritize and establish agreements with the business that are based on business importance, effort, cost and results.

• Communicate, communicate, communicate
