By focusing on delivery and control process activities, 'ITIL Service Operation' describes how a highly desirable steady state of managing services can be achieved on a day-to-day basis. The ITIL Editions 2011 has been updated for clarity, consistency, correctness and completeness.
The updated ITIL publications share a similar standard structure (including generic content in Chapters 1, 2 and 6) to improve consistency and aid navigation. Some content has been reorganized to improve flow and readability, and ensure alignment across the suite - including clarification around interfaces, and inputs and outputs across the service lifecycle.
Terminology has been clarified and made consistent across the publications and the ITIL glossary.
