Brian Johnson one of the ITIL founders is also the IT service management forum (itSMF) originator, present serves in CA’s ITIL to practice manager. He provided some idea to enterprise what is the ITIL 3rd edition key value? And who should face to the ITIL 3rd edition? Understand the core spirit before implementation. He aims at the detailed explanation how to select a correct ITIL framework version base on enterprise self requirement. As well as the key propose on ITIL Version 3 induction.
The ITIL 3rd edition has been published since May 2007, the service construction and life cycle's vision that has made the person a shine for it, but people get the puzzlement later on.
Johnson explain the different ITIL version between 1 and 3. What's the biggest difference on ITIL 3rd edition compared to version.1 and version.2? Each edition emphasis key point is dissimilar, for example version.1 and version.2 talked about IT service many are may choose (optional), or provided you a direction (guidance), but the 3rd edition, these things will be must (you should) probably working on. In the 3rd edition will advise (recommend) the enterprise to go to do, this will be 3 edition most main differences.
ITIL Version.3 is not uses for version.2 replacement. When the version.2 implementation is completed then can consider induction version.3 again at further. There has an assumption on version.3. it suppose the enterprise already to use ITIL v.2 to be very long, therefore enterprise expect their business more better, then upgrade to ITIL version.3. In other words, if enterprise inducts ISO 20000 very for a long time, wants to look for some better method, may also consider ITIL version.3. Enterprise selects the ITIL edition must according to their needs to decide that which edition can induct. Version.3 may not suitable for every enterprise.
If enterprise already achieves on ISO 20000 authorization, base on that foundation then can inducts ITIL version.3. Is necessary to upgrade to ITIL version.3? That depends on enterprise's commercial demand. What the enterprise needs to appraise is necessary take more investment improve to these standards? It is not for the ISO standard or ITIL certification and then works on the ITIL version.3.
If enterprise wants to take the ITIL version.3, they have to understand version.3 must the whole induction, it cannot be promote partially. It doesn’t like version.2 is service transmission, has more option. But version.3 is necessary whole induction.
When the enterprise inducts ITIL version 3 and provide the real services, how the enterprise can choose which part should play attention first? They can take the idea from Service Operation, as well as Service Transition books. According to the suggestion inside the book, think about what service is the enterprise wants to provide, whether all necessary flows did have, if does not have to probably make up these flows first and keep going.
If enterprise's IT management has not achieved on mature situation, but they want have better control on their working flow, which suits taking the ITIL version.2 methodology. If the enterprise many IT operations had been already mature, wants to advance manage on IT service life cycle, uses ITIL version.3 further.
In my view, ITIL framework establishment not one day and one night may become, it takes time and money, because the processes involve many subjects during the implementation. The category already depth also is broad. If take a wrong way, waste money and time. I strong agree as Brian Johnson mention, if enterprise faces to ITIL framework, they should divides the processes into short, middle and long term goal and then implement ITIL framework gradually. If enterprise doesn’t clear understand their IT management is it standing on the mature situation, find a consultant to do an assessment first. According to the assessment result, make up the weaknesses area and then take the ITIL Version.2 for the entrance. The achievements can obtain easily.
