  1. Configuration Management Block 13

  2. Overview Intent Be able to meet the responsibilities of EA for configuration management in Defence Content • Introduce ITIL • Determine risks of configuration changes • Report risks

  3. Why should EA bother about Configuration Management? • How many of you have been involved in Configuration or Change Management? • Why? • Can you give one reason why Configuration/ Change Management is important to EA?

  4. Welcome to ITIL • Who knows ITIL? • The Information Technology Infrastructure Library (ITIL) • set of (6) books describing good practice • produced by UK Office of Government Commerce • supported by IT Service Management Forum (ITSMF) • covered by BS15000 now (temp) ISO 20000 and AS 8018 Service management Parts 1 and 2 • has accreditation process … and increasing demand

  5. ITIL Service Support • We are most interested in ITIL Service Support • Have a look at Chapter 7 “Configuration Management” • And Chapter 8 “Change Management”

  6. Other Standards concerned with Configuration • ISO 20000 is not the only standard that mentions ICT Configuration Management • What else does? • ISO 12207: 1997 Information Technology -Software life cycle processes

  7. Configuration Management and Change Management Configuration Management = model of ICT in play(“As-is” Architecture) Change management= amending configuration because of problem or incident+ enhancing configuration to take up opportunity(amending Architecture short of full “To-be” analysis?)

  8. Change Management Process Basically • Receive request • Log request, compare with others • Determine initial impact • Gain approval from Change Advisory Board (incl business managers) • Consider risks of change and priority of effort • Incl impact upon EA (we hope) • Schedule changes • Make changes, test, and retest • Log effects

  9. Technology Regulatory Framework • In DefenceChange Management will be governed by the “Technical Regulatory Framework”

  10. Activity: Use of EMS • Use the Group Decision Support System (GDSS) or Electronic Meeting System (EMS) to discuss roles and responsibilities for configuration/ change management

  11. Use of AnnL in Change management • AnnL can be used to assess the risks of requested changes

  12. Systems Dependency “The hip bone is connected to the thigh bone …” • Some things are not important in themselves but they enable other things to happens • So, they “inherit” the importance of those other things What examples of dependency are there

  13. Reporting risks

  14. To Whom are Risks Reported? Under the Technical Regulatory Framework • Who analyses the risks? • What is the ‘house style for the risk report? • Who approves the changes?

  15. Yet another use of AnnL

  16. Activity: AnnL in Project Management • In teams • For 15 minutes • Go to the Task sections of the In sheet for the Case Study • Have a fiddle with some items • See what happens

  17. Change management as Projects • When does a change request become a project?

  18. Summary There is a pretty good process in place for managing changes to ‘configurations’ (EAs). It is all about managing the risks of proposed changes - even if it is not said that way. Next Block • Compliance and Audit will be considered in Block 17 • But next is …
