  6. ITIL is … The application of the science of management to information technology infrastructures, written down in a (semi-) structured manner in a series of books.

  7. ITIL Principles ITIL is all about which processes need to be realized within the organization for management and operation of the IT infrastructures to promote optimal service provision to the customer at justifiable costs.

  11. Definitions • QUALITY is the totality of features & characteristics of a product or service that bears on its ability to meet a stated or implied need (ISO 8402) • A PROCESS is a series of cohesive activities geared to achieving a certain objective. • IT SERVICE is a logical package of services that an IT organization offers, supplies and supports inorder to satisfy the client’s needs. • IT SERVICE MANAGEMENT is the sum total of management and commercial operation of the IT infrastructure, i.e., the delivery and support of IT services.

  13. Service level management is a process aimed at achieving the optimum level of IT Services through a good working relationship between the provider and the consumer. Service Level Management • Activities Comprising Service Level Management • Identify client’s requirements • Verify their feasibility • Propose, negotiate, agree on & set down service levels • Determine, draft and finalize standards • Check service standards and report on service

  14. Service Level Management Ensures continual identification, monitoring and reviewing of the optimally agreed levels of IT service as required by the business. This is done in close co-operation between the IT services providers and the customers (or their representatives. A Service Level Agreement specifies the services, the service levels, specific conditions and the parties involved.

  15. Service Level Agreement • The SLA • Definition of the pertinent operational services • Service levels agreed upon • Conditions under which the services are provided • Costs of providing the services • Identification of the parties involved • Service Levels • Costs • Continuity • Availability • Performance • Flexibility • Stability

  16. Capacity management is the process that ensures optimum utilization of IT resources, in order to achieve the level of performance agreed upon with the client. Capacity Management • Capacity Management Activities • Capacity planning • Modeling • Performance management • Resource management • Demand management • Workload management • Application sizing

  17. Capacity Management Supports the optimum and cost effective provision of IT services by helping organizations to match their IT resources to the business demands. Capacity Management Database (CDB): a collection of technical, business and organizational data, in order to provide capacity forecasts and plans.

  18. Availability management is the process that ensures the optimum utilization of resources, methods and techniques to achieve the level of IT services agreed upon with the client. Availability Management • Availability Management Activities • Compiling an availability plan • Meeting availability requirements • Monitoring availability • Monitoring maintenance obligations • Control / Security • Vulnerability / Risk • Reporting on the level of availability

  19. Availability Management To systematically identify availability and reliability requirements against actual performance and, when necessary, introduce improvements to allow the organization to achieve and sustain optimum quality IT services at a justifiable cost. Availability Reliability Maintainability Serviceability Resilience

  20. Contingency planning ensures that there are adequate technical, financial and organizational safeguards to protect the continuity of the IT services agreed upon in the SLA in the event of disasters. Contingency Planning • Activities Comprising Contingency Planning • Risk assessment • Risk management • Contingency plan management • Contingency plan testing • Reporting and communication

  21. Contingency Planning To develop and maintain plans for coping with and recovering from an IT crisis (i.e loss of service for a protracted period) and, where possible, to prevent IT crises from occurring. To “cope” means that work is moved to an alternate system in a non-routine way. Contingency: Unplanned situation in which it is expected that the period during which one or more IT services will be unavailable will exceed threshold values agreed to with the customer.

  22. Cost management is the process which yields relevant financial data to achieve a sound balance between price and performance at every level of operation. Cost Management • Activities Comprising Contingency Planning • Risk assessment • Risk management • Contingency plan management • Contingency plan testing • Reporting and communication

  23. Cost Management To monitor and provide insight into the costs of providing and supporting IT services; and if necessary (depending on the executive policy) recover the costs from customers in a fair and equitable manner. Cost Centre Accounting: costs are allocated to departments. Activity Based Costing: costs are allocated to Activities.

  24. Cost management is the process which yields relevant financial data to achieve a sound balance between price and performance at every level of operation. Configuration Management • Activities • Identification • Control • Status Accounting • Verification • Management Information

  25. Configuration Management Managing the IT infrastructure by recording all Items. Configuration Items (CIs): Components of the IT infrastructure that are (or are to be) under control of Configuration Management: hardware, software, procedures, documentation and people. CIs may vary widely in complexity, size and type – from an entire system to a single module or a minor hardware component.

  26. Cost management is the process which yields relevant financial data to achieve a sound balance between price and performance at every level of operation. Helpdesk • Activities • Communications & Promotion • Accessibility to Users • Managing Incident Control • Provide Continuity: Restore Service ASAP • Management Information

  27. Helpdesk An incident is any event that deviates from the (expected) standard operation of a system. Such an event influences the system, even though the influence may be small or even transparent to the users of the system.
