What are the most significant differences between V3 and V2?
The key point is that V3 articulates the relationship between IT and the business far more clearly than earlier versions of ITIL®. Instead of focusing on processes as in V2, V3 considers a wider view of IT by considering the lifecycle of a service from its initial planning, which should be aligned to business need, through to its final retirement. This allows a more thorough treatment of strategic options, functions, roles and responsibilities as well as continual improvement. The processes remain and have been improved. ITIL® V3 also looks more closely at alignment with other best practices and standards.
