  1. ITIL Introduction Linpei Zhang April, 2006

  2. What’s ITIL? ITIL (Information Technology Infrastructure Library) is a framework of best practices approaches intended to facilitate the delivery of high quality information technology services. - Wikipedia

  3. Okay, what exactly is ITIL? • A series of publications • Best Practices for IT Service Management • Processes • Guidelines • Checklists • Worldwide Industry standard • Management Philosophy

  4. Brief History of ITIL • The Central Computer and Telecommunications Agency of United Kingdom first published elements of ITIL in 1989. • The intention is to improve the management of IT services in UK Central Government • Contributed to by expert IT practitioners around the world. • The UK Office of Government Commerce was established in 2000 and incorporates the CCTA. • The OGC now owns ITIL and is responsible for its maintenance and further development

  5. ITIL Publications

  6. Putting them into context

  7. ITIL is the industry standard • Widely accepted in Europe, Asia and Australia • 170,000 ITIL certified professionals worldwide • Over 10,000 companies adopted ITIL worldwide • Started to gain momentum in United States • Over 2000 people attended itSMF USA Conference in Chicago, 2005, the ITIL “trade show”, representing over 700 companies • More than 1000 IT Professionals got ITIL certifications every month since 2005

  8. Corporate Procter & Gamble Capital One Boeing British Petroleum DHL Microsoft IBM HP Government UK Government Communications Headquarters IRS US Army Virginia Oklahoma City Who’s Using ITIL

  9. ITIL Tools • Over 100 Vendors • Well know tools supporting ITIL • HP Openview Service Desk • Remedy Strategic Service Suite • CA Unicenter Service Desk • Peregrine Service Center

  10. Frameworks Based on ITIL • HP ITSM Reference Model • “a model that combines ITIL and industry-standard best practices with years of HP knowledge and experience.” • Microsoft Operations Framework (MOF) • “Applying the principles of ITIL to the Microsoft technology platform, MOF provides a foundation to help IT organizations meet the challenges”

  11. Other useful frameworks focus on IT efficiency • COBIT (Control Objectives for Information and Related Technologies) • CMM (Capability Maturity Model) • Six Sigma • Balanced Scorecard

  12. International Industry Standards • BS15000 • Published by BSI (British Standards Institution) in 2000 as national standard for UK • ISO20000 • Published by ISO (International Organization for Standardization) on 12/15/2005 • The first International standard for IT Service Management. It’s based on and has superseded BS15000. • Both standards are based heavily upon ITIL

  13. ITIL Philosophy • Service • Quality • Process • Measurement • Cost • Proactive

  14. ITIL Philosophy One - Service • IT Service Management (ITSM) means managing IT as a service business. • Deploy and manage resources to a discrete set of defined services • Thinking ourselves as Service Providers

  15. Application Services EasyPay EasyPayNet TeleNet DAS AOS FLT EEE … Construction Services Support Services Network Support Service Application Maintenance Service Database Maintenance Service Infrastructure Maintenance Service Management Services Statistics and report Communication and Training Consulting What kinds of services are we providing?

  16. Behave like Service Providers • Align IT services to the customer and business needs. Find out what the customer needs and make those services available • Partner with the customer to create new ways of doing business. Create new competitive advantages. • Increase the quality of the existing services by organizing around services and working to make those service efficient

  17. Realize the promise “We care about our Customer!” • Documenting, negotiating and agreeing Customer and business quality targets and responsibilities in Service Level Agreements (SLAs) • Regular assessment of Customer opinions in Customer Feedback and Customer Satisfaction Surveys • IT personnel regularly taking the ‘Customer journey’ and sampling the ‘Customer experience’ • IT personnel taking the Customer and Business perspective and always trying to keep Customer interactions as simple and enjoyable as possible

  18. Expected Results • Alignment – Better match IT capability and costs to business needs • Efficiency – Extend existing resources • Reliability – Ensure consistent performance • Agility – Response to business and technology-driven changes

  19. ITIL Philosophy Two - Quality • Quality is the “degree to which a set of inherent characteristics fulfils requirements” as in ISO 9000 • Service Quality is “about ensuring customers get what they want” as in Managing Service Quality • Quality is a interactive term. It’s all about satisfying and exceeding Customer Expectations.

  20. What does that mean? • High quality of the product cannot be achieved without understanding what customer wants (requirements) • Quality cannot be measured without asking the customer’s opinions • High quality service cannot be delivered without thinking in customer’s perspective

  21. How Customer Evaluate Service Quality? • Did the service satisfy my expectation? • Can I get the same service next time? • Is the service provided by a reasonable cost?

  22. Parking Reception desk Waiter/Waitress Take order Food delivery Food Feedback Billing Farewell The quality of the dinning service is based on the quality of ALL the services above! A High Quality (Pleasant) Dining Service Question: How to improve the quality of our IT Services? How can you contribute?

  23. Where are we now? Current process & procedures Current challenges & problems Where do we want to be? What are the priorities? How do we bridge the gap? How do we get where we want to be? Informed planning Experienced execution Are we improving? Did we get to where we wanted to be? Strict control Status communication Continuously Improve Service Quality How do we keep the momentum going

  24. Deming Circle (PDCA) Plan: Plan ahead for change. Analyze and predict the results. Do: Execute the plan, taking small steps in controlled circumstances. Check: Study the results Act: Take action to standardize or improve the process How to get there - Quality Improvement Model

  25. ITIL Philosophy Three - Process “A process is a specific ordering of work activities across time and space, with a beginning and an end, and clearly defined inputs and outputs: a structure for action. ... Taking a process approach implies adopting the customer’s point of view. Processes are the structure by which an organization does what is necessary to produce value for its customers.” - Thomas Davenport, “Process Innovation”

  26. Characteristics of Processes • Definability: It must have clearly defined input and output • Order: It must consists of activities that are ordered by time and space • Customer: There must be a recipient of the process’ outcome • Value-adding: The transformation taking place within the process must add value to the recipient

  27. Result vs. Process • Result Oriented Management • Results can map to Activities • Results are measurable and worth measuring • Only applicable for low risk task • Process Oriented Management • Define a process to achieve the result • Break down the overall result into smaller intermediate results • More control and lower risk

  28. Why we need Process to provide high quality service? • Service • Intangible: Customer Experience • Interactive: One-time, Cannot be stored • Process can help • Consistent performance • Reduce risk • Repeatable: Customer experience can be repeated next time

  29. Give Understand the whole picture Know what to do in any circumstances Clearly defined Roles/Responsibilities Measurable performance Save time and efforts Take May change way we used to carry out our tasks Take away some flexibilities But, what does process mean to me?

  30. ITIL Philosophy Four - Measurement If you cannot measure it, you cannot manage it If you cannot measure it, you cannot improve it If you cannot measure it, you probably don’t care about it If you cannot influence it, you don’t need to measure it

  31. Check in PDCA Evaluate if we are in the right direction? What do we mean “Measure” here? Goal Are we in the right direction? Start Point

  32. Why “Best Effort” is not good enough? • “Best Effort”, “Some Progress”, “Improved Performance”… are not measurable. • “Performance is improved 10%”, “Time to Market decreased from 100 days to 50 days”, “Customer Satisfaction Rate improves 23 percents”. Those are good measurements. • All the measurements must be quantitative!

  33. What to measure? • Goal (Where do we want to go? What are we want to achieve?) • CSF – Critical Success Factors: Determinate factors to achieve the goal • KPI - Key Performance Indicators: Compare the CSF with standards, Quantities measurements

  34. Example: Measure Availability

  35. KPI for Availability • MTTR (Mean Time to Repair): Average Down Time including Detect Time and Resolve Time. • MTBF (Mean Time Between Failures): Average Normal Operation Time • MTBSI (Mean Time Between System Incidents): Average time between two incidents • Availability Ratio: MTBF/MTBSI*100%

  36. Not too little, not too much • Measurement has costs • Tools • Time • Report • Analysis • Too many measurements only ends up with No measurement • Only measure the KEY performance indicators

  37. ITIL Philosophy Five - Cost Everything comes with a cost • Equipment Cost • Software Cost • Organization Cost • Accommodation Cost • Transfer Cost • Cost Accounting

  38. How Cost are related to us? • Budget • Salary/Bonus • Reimbursement • Training Cost • Tools • Hiring • It’s everywhere in our working life! (Personal life too)

  39. Cost Awareness – Thinking as the Management • Budget • Can we make the ends meet? • New Project • ROI (Return Of Investment) = Profit / Investiment • New Software/Hardware/Tool • TOS (Total Ownership Cost): Cost in its lifetime

  40. Hidden costs • Management cost • Statistics and Report • Communication and Training • Support cost • Installation/Upgrade • Incident Support • Performance Tuning

  41. Efficient IT Service • Cost • Investment • Spending • Quality • Capacity • Availability • Performance • Support • Disaster Recovery • Customer Requirement • Can quality and cost satisfy the business needs?

  42. ITIL Philosophy Six - Proactive • Common feelings about work • I am too busy • Work is chasing me. I am stressed out • I don’t have time to do the meaningful things. • Those issues are so bugging. They kept coming back!

  43. Breaking things down • Reactive activities • Handle customer complains • Handle production outage • Last minute purchase • Deal with disasters • Preventative activities • Create contingency plan • Setup knowledge database • Setup Production Monitors • Capacity Planning • Create Disaster Recovery Plan

  44. First thing first • The more you work on Preventative Activities, the less you need to work on Reactive Activities • Take the control back! • Preventative activities are under your control while Reactive Activities control you.

  45. Some Proactive Activities Suggested by ITIL • Problem Management: Study the trend of the incidents. Dig out and fix the fundamental problem. • Configuration Management: Keep track of important things and their relationships • Capacity Management: Project the workload. Plan the capacity ahead of time • And a lot more….

  46. What’s actually in ITIL? • Goals/Benefits • Processes • Guidelines • Check lists • Critical Success Factors • Key Performance Indicators • Implementation tips

  47. Service Lifecycle • Design: Requirements • Define: Service Level Agreement • Delivery: Construct, Test, Release • Support: Incident, Problem, Change • Measure: Service Level Report • Improve: Service Improvement Plan

  48. Core ITIL Processes

  49. Service Delivery • Face the Customer. Satisfy Customer requirements • Business driven • Strategic level processes • Forward-looking, planning, proactive activities • Do the right things

  50. Service Delivery Processes • Service Level Management: Define a service catalog; Identify, negotiate, monitor and review service level agreements (SLAs) • Financial Management: Review budgeting, charging and IT accounting; analysis of running costs and charging policies • Availability Management: Review of reliability, availability, resilience, maintainability and serviceability; plan, monitor and report availability
