ISCA - CA Final - Short Notes on ITIL


ITIL is an acronym for Information Technology Infrastructure Library. ITIL are a series of books and training manuals that outline and explain the practices that are the most beneficial to IT services (usually manager focused). The goal of ITIL is for managers to have extremely high standards in IT value, as well as high financial quality in day to day IT operations. ITIL procedures are supplier independent and include instructional materials on IT infrastructure, operations and development issues.

It should be noted that the acronym ITIL is a registered trademark, and the books included in the ITIL library are copyrighted as well.

ITIL has had a long history of development, and many IT professionals believe that ITIL grew out of the yellow books, which were best practices and guidelines that were used in IBM during the 1980's, however it wasn't until the middle of the 1990's that ITIL become a formal library of IT best practice frameworks. The newest version of ITIL (version 3) is set to be released in May of 2007. The ITIL v3 has been anticipated by many IT professionals all over the world for the last few years. It is expected that five core texts will be packaged in the publication, they include: Service Strategy, Service Design, Service Transition, Service Operation and Continual Service Improvement

The original ITIL library included several books that covered specific themes in IT Service Management. However, after the original publication, the books in the library grew to over 30 volumes. Since 30 volumes can be cumbersome, difficult to read and digest and expensive to purchase as a complete set, the second version of ITIL has been consolidated.

ITIL v2 was packaged differently; version 2 was sold in sets that related to process guidelines and included several different aspects of IT including applications, services and IT management. It should be noted that the most popular sets being sold in ITIL v.2 include the services set, specifically Service Support and Service Delivery. While these two sets are by far the most popular, the ITIL library used as a whole is extremely comprehensive and a good foundation for any business using IT components today.

Following is a list of the books included in ITIL version 2:

Advantages of ITIL

There are several benefits for using the Information Technology Infrastructure Library for many of your IT business needs and one main benefit is that through the guidelines and best practices that are taught in the library, your business can save a tremendous amount of money once implemented.

Another advantage of ITIL is that it will help your IT department organize and manage many different disciplines using one comprehensive volume. ITIL is the leader in IT guidelines and best practice publications; it has been tested in real world environments for over a decade and is proven to work.

Disadvantages of ITIL

While the advantages usually far outweigh the disadvantages, there are a couple of criticisms that are worth noting including the idea that most IT professionals consider ITIL a holistic approach to IT management. While ITIL is comprehensive, even the publication itself does not consider itself a holistic approach to IT management.

In addition, there are also accusations by some IT professionals that following only the ITIL due to its acceptance by many IT managers as the authoritative source has actually led to many businesses to skip pragmatic solutions for their specific business needs. Finally, another criticism of ITIL is that while some topics are covered extensively and are of high value, other topics may not receive enough emphasis with quality being uneven in certain publications.
