Since the ISO/IEC 20000 standard, which defines the requirements for an IT service management system, now exists and is based on ITIL version 2 — why bother with a version 3?
The ITIL version 3 development team is required to ensure that ITIL version 3 continues to support ISO/IEC 20000. The current ITIL guidance successfully puts IT organizations on the path to ISO/IEC 20000, so don’t abandon current projects or become concerned that IT will not reach its goals with the arrival of ITIL version 3 — it will support this standard. Of course, good practice theory (like the processes implemented in an organization) will continuously be improved over time, so it is not unreasonable to consider updating guidance such as ITIL or ISO/IEC standards periodically. ISO/IEC 20000 will transition over time based on requirements of the international community. Brian Johnson is one of the original authors of the first ITIL books and an ITIL senior practice manager for CA. He has also authored more than 15 books on ITIL or related topics and is the founder of the IT Service Management Forum, a professional organization focused on IT service management and ITIL.
