2 Getting Operations Wrong Bites Development Where s my project gone? Infrastructure Where s my money gone? Operations Where s my business gone? 1/18/2007 2

3 What is Service? of the agreed service to meet the customers requirements 1/18/2007 3

4 Introducing ITIL ITIL Information Technology Infrastructure Library. Service Processes. Developed by the Office for Government Commerce (OGC) in England (late 1980 s). Best practices focused on the management of IT service processes. Open source. 1/18/2007 4

5 ITIL Service Goals Ensure that IT services are aligned to the needs of customers and users (measurable). Improve availability and stability of services. Improve communication within IT and with users. Improve efficiency of internal processes. Ensure that all information is evergreen. 1/18/2007 5

6 ITIL Service (ITSM) Two main components: Service Support five processes that provide support for day-to-day operation of IT services. Service Delivery five processes that focus on long-term planning and improvement of IT services. These two components are linked together through the Service Desk. 1/18/2007 6
