1 Beginners Guide to ITIL - help or hindrance? Dennis Adams a s s o c i a t e s Management and Infrastructure SIG Meeting Can it help me? What are the pitfalls? Dennis Adams 4th October 2006

2 Introduction Why we are doing this … (Target Audience) –Confused by what ITIL is? –Heard the buzz-words, but not sure of the substance? –Scared by the prospect of being inundated with too much processes, so that your teams are unable to get any work done? These are all typical reactions from technical leaders and managers when faced with the ITIL “hype”. The purpose of this presentation is to introduce what ITIL is really about, and take away the mystery. Explain and Justify PROCESS to TECHNICAL Audience. “ITIL for Dummies” ?

3 Topics to Cover What is ITIL ? What do we mean by a “Process Approach” to the world as a different way of looking at how we work together ? What are the main Processes within ITIL ? What some of the main Processes look like in more Detail The importance of the Configuration Management Database (CMDB) Conclusions: Don’t “Implement ITIL?” (!?) Time for Questions…

4 The ITIL definition of IT “Service” - is this helpful ?? “An integrated composite that consists of a number of components such as management processes, hardware, software, facilities and people that provides a capability to satisfy a stated management need or objective.” Dictionary of IT Service Management

5 Think of MANAGING IT as PROVIDING a SERVICE IT SERVICE SERVICE DELIVERY SERVICE SUPPORT BUSINESS Align IT services with the needs of the Business Improve the Quality of the Service Reduce the long-term costs

6 Think in terms of PROCESSES rather than SKILLS Functional Organization Process Approach Using a Process Approach, we no longer think in terms of individual technical teams “doing their own thing”. Rather we think in terms of the overall goal which should be directed to the main goals of the organization.

7 What is ITIL? ITIL = “Information Technology Infrastructure Library” A Library of Processes books outlining “good practice” for managing IT Infrastructure. A set of ready-made “how to” references. ITIL IS A NON-PRESCRIPTIVE REFERENCE ITIL® is a Registered Trade Mark, and a Registered Community Trade Mark of the Office of Government Commerce, and is Registered in the U.S. Patent and Trademark Office ITIL revision 3 is currently being written. A British Standard (BS 15000) certification (BS to come). Linked to ISO 9000 Quality Certification.

JFDI ? Development Methodologies define Ways of Working to ensure that we do things in a Repeatable, Professional manner.

13 EXAMPLE: What is CAPACITY PLANNING ? BUSINESS CAPACITY MANAGEMENT Future Service requirements from the Business Future Capacity from the Business Resource Requirements in future. CAPACITY PLAN SERVICE CAPACITY MANAGEMENT What are the existing requirements? Are we meeting SLAs? How well are we utilising existing resources today? RESOURCE CAPACITY MANAGEMENT How well are we using existing technology? Are we using each component appropriately? What future technologies could be better?

15 Some Best Practices in the ITIL Library How to get the best benefit from a SERVICE DESK –Single point of contact, Monitoring and escalation on behalf of customers. A systematic way of managing INCIDENTS: –Log / Classify / Investigate / Diagnose / Resolution Being Pro-Active: PROBLEM MANAGEMENT –Root Cause Analysis, Kepner & Tregoe Analysis, Ishikawa diagrams. Keeping track of IT Assets: CONFIGURATION MANAGEMENT Stopping dangerous changes: CHANGE & RELEASE MANAGEMENT –Impact Analysis and Authorisation before Changes Being Customer-Focused: SERVICE LEVEL MANAGEMENT Bean-Counting: FINANCIAL MANAGEMENT –Charge-back to reflect the cost to the Business. CAPACITY: Prediction instead of Panic AVAILABILITY –Design for continual up-time DR and BCP: IT SERVICE CONTINUITY –Risk Assessment and Planning

16 Why implement ITIL-based processes? ITIL emphasises that IT should be seen as a service to the business. ITIL could be (part of) a Quality Management strategy to improve the quality of the IT Service for the business. Introducing clear processes should enable the company to grow and/or bring on more staff more easily. Being based on a “best practice” approach means that you do not have to reinvent the wheel. Cost reduction - Standardising “how you do things” can simplify and reduce costs. Professionalism / Clear points of contact with external organisations and stakeholders.

17 The BEST WAY to Implement ITIL Service Management? Incident Problem Change Release Configuration Service Desk Configuration Management Database (CMDB)

21 Pitfalls and Warnings “Organisations should not be over ambitious when implementing Service Management” (IT Service Management “Little ITIL”). DON’T “IMPLEMENT ITIL” –ITIL is a Framework of Best Practices, not a Prescriptive Manual –Use what is useful, when and where it is useful. Remember that any IT Process will only work if the participants have the right data in the right place at the right time. –Configuration Management Database (CMDB) Remember that the objective is to document and implement repeatable processes in order to make the organisation more efficient and/or more responsive to customers. –ITIL should never been seen as an end in itself.

22 Some Recommendations See ITIL processes as a way of standardising what is already done / should be already done. –Everyone should benefit from simplified and clearer ways of doing things. Consider the ITIL Foundation Exam –For most IT Infrastructure Professionals, it is “common sense” –Looks good on the CV –Gives you a common “vocabulary” for discussing how things are done –Emphasises “customer focus” and “process” –40 questions multiple-choice, pass mark is 25. Keep asking “what is the business benefit ?”

23 Further Useful Information OGC Home Page for ITIL: TSO (The Stationery Office): IT Service Management Forum (itSMF): Interactive Forum: ITIL Toolkit: Key Skills Training: Square Mile Systems: Pink Elephant Consultancy: Dennis Adams Associates:

24 Questions? Is ITIL a panacea for all IT Infrastructure Management challenges? –It never claims to be ! –It is a set of good practice processes to be used as a “toolkit” –ITIL itself speaks about: Process / Product / People. –Implement ITIL as part of a Strategic Cultural change in the organisation, which should include: Metrics, Operational Tools, Processes, Standards. Can you implement “parts” of ITIL and ignore the rest? –Yes. –Remember that to make processes succeed you need appropriate data.
