Many practitioners in the industry try to learn/approach a domain through a framework or standard – where it should be the other way around!  Understanding the specific nature, context and challenges of a domain can make selection and adoption of standards and framework much more beneficial. Understanding the context of  Service management –> IT Service Management and then look at ITIL and/or ISO/IEC 20000 is a case in point. Many attempt to understand IT Service management domain through ITIL and ISO/IEC 20000. 

This problem is not limited to ITSM domain alone. It is equally applicable to Information Security, IT governance etc. 

Just blogged my thoughts on the same on our Wings2i official blog:
