  • IT Service Delivery – An Enterprise Approach Mark Guidry October 18, 2007
  • What Is IT Service Delivery?
    • Service Delivery is the method by which an organization acquires, maintains, supports and operates its IT infrastructure
      • Hardware
      • Networking
      • Software
        • Custom
        • Vendor supplied
      • Security
  • IT Service Delivery - Implementation
    • Often a home grown collection of organizational structures and processes
      • “Ad Hoc” evolution
      • No clear governance model
      • Not process driven
      • Unclear roles and responsibilities
      • Inflexible – may hamstring the business as it grows and evolves
  • Process Frameworks
    • A Process Framework Provides High level Process Structure and Definition
      • Defines process areas and their relationships
      • Supplies a governance model
      • Does not define process details
      • Does not specify policies
    • There Is An Industry Standard Process Framework For IT Service Delivery
  • IT Infrastructure Library (ITIL)
    • Started by British Government as collection of best practices for IT service delivery
    • Evolved into an IT governance model for service delivery
    • De facto standard for enterprise services delivery - process framework
    • ISO standard (ISO 20000/BS 15000)
  • Why Use ITIL?
    • You Don’t deliver consistent services or support
    • You are in the business of fire fighting rather than delivering
    • Your clients come to you with solutions rather than problems
    • You have cross functional communication problems and silos
    • You are unable to easily answer questions about your environment and systems
    • Poor understanding of capacity and financial conditions
  • ITIL Primary Model
  • Service Support Process Areas
  • Configuration Management
  • Service Desk
  • Incident Management
  • Problem Management
  • Change Management
  • Release Management
  • Service Delivery Process Areas
  • Availability Management
  • IT Service Continuity
  • Capacity Management
  • Financial Management
  • Service Level Management
  • Security Management
  • What Should You Expect From ITIL?
    • Improve the quality and speed of responses to customers
    • Be Pro-active versus Re-active
    • Reduce the overall number of incidents
    • Find permanent solutions
    • Improve control of SLA performance
    • Improved management decisions using service and customer centric data
    • Targeted, considered investments to gain operational efficiencies through use of proven best practices
  • Conclusion
    • If you’ve done IT Service Delivery you will understand ITIL
    • Start small and grow by iteration
      • ITIL “out-of-the box” is large
