ITIL Intermediate: There are two streams in the Intermediate level: the Service Lifecycle Stream and the Service Capability Stream. You can opt to take individual modules within this level, however, if you wish to progress through the ITIL qualification scheme you will need to earn a minimum of 17 credits (two credits must be earned from Foundation) before you can take the Managing across the Lifecycle module and exam. By passing this, you will achieve a total of 22 credits, which you can use towards the ITIL Expert level of certification.
ITIL 2007 edition (previously known as ITIL Version 3) is an extension of ITIL Version 2 and fully replaced it following the completion of the withdrawal period on 30 June 2011. ITIL 2007 provides a more holistic perspective on the full life cycle of services, covering the entire IT organization and all supporting components needed to deliver services to the customer, whereas ITIL Version 2 focused on specific activities directly related to service delivery and support. Most of the ITIL Version 2 activities remained untouched in 2007, but some significant changes in terminology were introduced in order to facilitate the expansion.
