  • 13. Case Example Supporting Implementation of Incident Management and the Service Desk
    • Implementation of Incident Mgmt has resulted in a decrease of down time per user. This is defined as the amount of time a user is on the phone to the Service Desk or cannot work because of failure.
    • If the downtime per user is reduced by one minute per person per day, this saves the organization: $83,000.00/annually
    • (500 users*200 days*$50/hr*1min)
  • 14. Problem Management
    • Objectives
      • Stabilize Services Through

  • 16. Cost/Benefit Analysis of Problem Management
    • Implementation of formal Problem Management decreases the number of recurring incidents by 500 (10% of the total incidents annually. This equates to a cost savings to the company of $4,150 per year
    • (500 incidents*$50/hr*10 min)
  • 17. Change Management
    • Objective
      • Only Approved Changes Made to enterprise configuration

  • 18. Change Relationship Model
  • 19. Case Example in Support of Change Management
    • Two changes are implemented simultaneously, resulting in a major problem:
    • The customer support system fails, resulting in a loss of 50 Customers with an average purchasing power of $500.
    • This has just cost your company $25,000 in potential revenue.
  • 20. Configuration Management

    • Manage the Scope & detail of the Configuration Management Database
  • 21. Configuration Levels
  • 22. Cost Benefit Analysis of Implementing Configuration Management
    • After formalizing Configuration Management across all platforms supported by the Service Desk, The Service Desk Agents have a much greater insight into the relationship between users, configuration items and incidents. The three people assigned to incident matching can be reduced to two resulting in a benefit of $80,000/yr
    • (200 days a yr*8hrs/day*$50/hr)

      • Change Management (Control)
      • Configuration Management (Control & Administration)
  • 24. Major Activities of Release Management
  • 25. Case Example Supporting Implementing Release Management
    • Suppose a software “patch” is installed to a widely used system and has a “bug”. The previous version should be reinstalled but due to poor version management, the wrong version is used, resulting in a system shutdown that lasts three hours and affects two-thirds of all employees. This will cost the organization $50,000 in lost productivity
    • (500 users*$50/hr*3hrs*2/3 of users)
  • 26.
    • ITIL's framework is not an inflexible set of standards.
    • The guidelines can be adapted to suit different business and
    • organizational environments.
    • Don't spend time in areas where processes are satisfactory
    • and close to complying with ITIL guidelines.
    • Part-time implementation of ITIL processes will slow project
    • completion but result in easier adoption by staff
    • Identify areas for quick wins to demonstrate the value of
    • improved processes.
    • Process improvement always requires a senior executive to
    • champion the endeavor while promoting the values and
    • maintaining the project's focus.
    • An active steering committee also is essential to sustain participation across the management team.
  • 27. Bottom Line: Enterprises will realize valuable process improvements and better measurement and reporting of process outcomes through the adoption of ITIL processes and guidelines. Source Gartner -2003
