ITSM - ITIL


IT service management is all about providing efficient IT services which help meet business objectives.  The origins of the phrase “IT Service Management” or ITSM are not clear and no organization or entity can claim ownership of this phrase. “Service" in an IT perspective typically is viewed from the prism of IT Operations. However ITSM is not about IT operations alone. ITSM encompasses the complete IT practise in an organization. 
“Service management is a set of specialized organizational capabilities for providing value to customers in the form of services”
ITIL Service Strategy Core Book
Being process-focussed, ITSM can be equated with any process improvement framework such as TQM or Six Sigma.  ITSM is vendor agnostic. In short it provides for a system to structure IT activities in an organization and the interaction of IT personal with business or the consumer of services.
ITIL or Information Technology Infrastructure Library is a specific framework for ITSM tasked with aligning IT services with business needs. The origins of ITIL are in the period of the 1980’s when the UK government realized the growing dependence of Government on IT and the need for creating standard practises. The UK Government's Central Computer and Telecommunications Agency (CCTA) was tasked to come up with recommendations to manage IT services in a more efficient manner. The result was a library of 42 books grouped subject wise providing practical knowledge aimed at management, and not focussing on technology.
 Over the years the ITIL Framework has undergone various changes, responding to the changes in the IT environment from the Mainframe era, outsourcing and now the latest “Cloud and Big Data”.
The first major revision in ITIL was done in early 2000 when version V2 was released. The emphasis continued to be operations even then.  The need to address the issues of IT strategy and “continual service improvement” as a separate focus was recognized in the next major revision of ITIL V3 which was released in 2007. ITIL V3 addressed a cyclical approach to Service Management and thus was born the “Service Management Lifecycle”. The importance of this shift can be assessed from the strategic perception of IT and it is fundamental importance in any business.
Today ITIL is published in a series of five core publications with a each book covering a specific stage of the lifecycle. The latest update came in July 2011 when the ITIL 2011 edition was published. ITIL is a registered trademark of the United Kingdom's Cabinet Office

What is a Best Practise



 
A Best Practice is a technique or series of techniques that provide a means of achieving better results.

In the words taken from http://www.best-management-practice.com/ which is managed by the TSO and APMG in conjunction with the Cabinet Office, UK,

“They present flexible, practical and effective guidance, drawn from a range of the most successful global business experiences.”

Since a best practice helps produce a better result than other employed means, it often becomes a benchmark. However Best Practises are constantly evolving due to their very nature. As and when improvements are noticed they are incorporated into the best practise so that you may have various versions of a best practise.  A Best Practise can in a way be stated as a standard way of carrying out an activity or a series of activities.

Quite often a Best Practise is an alternate to a recognized standard and is used to help maintain or set a quality standard. Best practises often have associated standards. A classic example is the case of the ISO 20000 standard for IT Service Management. The associated Best Practise for IT Service Management is ITIL. The difference between the two is that a “Standard” is a must to adhere, while a Best Practise is a “Good To Adhere”. Many industries have best practises unique to them. For example the IT Industry has ITIL and CoBIT. Project Management has Prince2 and PRISM amongst others.
