If you are new to ITIL or ITSM you may have seen these two words being used interchangably and may think that they are synonymous with each other. You may have to understand both these terms to know that ITSM is not synonym with ITIL exclusively. Here are the two terms explained:
IT Service Management (ITSM): It is a sort of discipline or methodology that uses a process approach to manage small, medium or large scale Information Technology Infrastructures. It puts the customer first by emphasizing on customer centric philosophy. ITSM is often associated with many other management methodologies like Six Sigma, Total Quality Management, COBIT and Business Process Management. IT Service Management initiative is always concerned with either deliveing or supporting IT services to meet the organizational business requirements.When you take up a ITSM initiative it is up to you which framework (or good practice) you would like to adopt, depending on what suits you the best. For example if your organization uses Microsoft technologies in your information technology applications or your infrastructure then
Microsoft Operations Framwork (MOF) may be the best bet as MOF provides guidance based on Service Management Function (SMF) Operations guide. What is this MOF?..Well the basis of MOF is ITIL but Microsoft has provided specific guidance applicable to customers using microsoft technologies in their IT Infrastructure and therefore MOF itself is a proven Good Practice as it is resultant from experience of Microsoft customers. I can say that for Microsoft customer organizations this is the best as MOF documentation is short and available for
Free on Microsoft website.
ITIL®: This is the most widely accepted process oriented framework or Good Practice (a service management framework) for managing IT services. There are other service management "Good Practices" which can be used to manage your IT services. For Example
Microsoft Operations Framwork (MOF) for organizations using Microsoft technologies, i repeat MOF is based on ITIL but provides additional guidance. The other Good Practices available to address your specific IT Service Management initiatives are
