Introduction to ITIL
![Page 8: IT Operation to Global Standard Satit Prasitwuttivech Consultant Datacraft (Thailand) Ltd.](https://reader035.fdocuments.us/reader035/viewer/2022070308/551bfc24550346a34f8b49a4/html5/thumbnails/8.jpg)

What it is
ITIL = IT Infrastructure Library A comprehensive and consistent set of best practices for IT service
management, promoting a quality approach to achieving business effectiveness and efficiency in the use of information systems
Commissioned by the British Government’s Central Computing and Telecommunications Agency (CCTA) to drive down IT costs and improve performance and efficiency in the 80’s
It is based on the collective experience of commercial and governmental practitioners worldwide
A framework of practices (guidelines), independent of organisation size or sector
A process-driven approach It is Current (ITIL V3)
![Page 9: IT Operation to Global Standard Satit Prasitwuttivech Consultant Datacraft (Thailand) Ltd.](https://reader035.fdocuments.us/reader035/viewer/2022070308/551bfc24550346a34f8b49a4/html5/thumbnails/9.jpg)
9
What it is not
Not a set of rigid rules, policies or a methodology Not a maturity model Not a religion Not the answer to all business problems or process
issues Not just a set of diagrams / processes handed out by
Management that people need to follow
![Page 10: IT Operation to Global Standard Satit Prasitwuttivech Consultant Datacraft (Thailand) Ltd.](https://reader035.fdocuments.us/reader035/viewer/2022070308/551bfc24550346a34f8b49a4/html5/thumbnails/10.jpg)

What the Framework provides?
• A common terminology (internal to Didata and with our Clients)• A more reliable and consistent approach to service delivery
– Consistent global processes– Consistent global interfaces, look and feel
• Clearer expectations and responsibilities• Increased productivity and accountability• Improved service availability• A more professional relationship with our clients / Vendors /
Third Parties• Increased customer satisfaction and internal confidence• Reputation

Who uses ITIL
![Page 12: IT Operation to Global Standard Satit Prasitwuttivech Consultant Datacraft (Thailand) Ltd.](https://reader035.fdocuments.us/reader035/viewer/2022070308/551bfc24550346a34f8b49a4/html5/thumbnails/12.jpg)
12
Where is it going?
• Currently defined by the British Standard BS15000
• Equivalent standards (based on BS15000) have been adopted in SA and AU– SANS 15000-1:2004 IT Service Management Part 1:
Specification for Service Management– SANS 15000-2:2004 IT Service Management Part 2: Code of
Practice for Service Management– AS8018
• BS15000 standard is on the ISO standards fast-track
• Expect publication of ISO 20000 some time during 2006

Why do we need to change?
• Current resource levels failing to meet business demands and too expensive
• Current service perceived as poor or simply “Ok” by Clients (slow, inconsistent, unstable)

Positioning: The Service Profit Chain

Comments from Gartner
• IS organizations are being asked to make the most of what they have and still deliver cost management improvements. To meet these demands, many have turned to refinements and efficiency improvements through benchmarking, best practices, processes and standards analysis. The IT Infrastructure Library (ITIL) has been at the forefront of best-practice and process methodology. (Gartner, 2004)
• Prediction: Twenty percent of large IT organizations will rely on IT process improvement to lower operational costs by 10 percent by year-end 2005 (0.9 probability), rising to 40 percent of large IT organizations by year-end 2007 (0.7 probability). (Gartner, 2004, G00124665)
• Adoption of process- and service-based IT delivery capabilities will not only enable IT to better respond to regulatory compliance issues, lower costs and improve operational effectiveness; these capabilities will also build competencies that can position IT to assume greater responsibility for business processes. (Gartner, 2004, G00124665)

Incident Management
• Objectives– Prevent service level breaches through timely resolution of incidents
– Assist Problem Management in identifying trends in incidents
– Ensure all incidents are correctly detected and recorded
• Incident = 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.
• Service is restored by the fastest means available. This may be a temporary fix, e.g. swap the device
• Usually SLA driven (e.g. service restoration metric)• Make use of Known-Error database and other Vendor data sources to
determine resolution
Restoring normal service operation as quickly as possible and minimising the adverse impact on business operations
![Page 35: IT Operation to Global Standard Satit Prasitwuttivech Consultant Datacraft (Thailand) Ltd.](https://reader035.fdocuments.us/reader035/viewer/2022070308/551bfc24550346a34f8b49a4/html5/thumbnails/35.jpg)
35
Problem Management
• Objectives– Reduce the overall number of IT incidents– Minimise the impact of incidents and problems on the organisation– Ensure that the correct level and number of resources are focused on problems– Manage information that will allow for better future resolution of incidents– Progress Problems to Known-Errors
• Focus on determining and resolving the underlying cause of problems• Reactive and proactive components
To minimise the adverse impact of incidents and problems on the business caused by errors in the IT infrastructure and to prevent the recurrence of incidents related to these errors

Configuration Management
• Configuration Management Database (CMDB) is a virtual relational database
• 4 Stages of Configuration Management– Plan– Identify– Control– Status accounting– Verify
• Asset Management focuses on asset lifecycle management, whereas Configuration Management on its role in IT service provision rather than it’s cost
To identify, control and audit the information required to manage IT services by defining and maintaining a database of controlled items, their status, lifecycles and relationships, and any other information required for cost effective IT Service management

procedures• Approval includes Business, Technical and Financial components• A single change calendar (forward schedule of changes) is
maintained across the organisation to minimise conflicting changes
Controlling changes to the infrastructure or any aspect of services, with minimum disruption, through a formal, centralised process of approval, scheduling and control to ensure continued alignment to business requirements
![Page 38: IT Operation to Global Standard Satit Prasitwuttivech Consultant Datacraft (Thailand) Ltd.](https://reader035.fdocuments.us/reader035/viewer/2022070308/551bfc24550346a34f8b49a4/html5/thumbnails/38.jpg)
38
Release Management
• Key activities– Release policy, planning, design, build management and
testing– Communication with Change Management and the Client– Audits of Configuration Items before and after the release– Storing and restricting access to controlled software– Installation of new / updated hardware– Release, distribution and installation of software
