Microsoft has recently published two interesting whitepapers mapping its Microsoft Operations Framework (MOF) to ITIL V3 and ISO/IEC 20000:
I have always been a big fan of MOF - it makes sense, is filled with question-based guidance and it's free. Microsoft has graciously provided free job aids, templates and whitepapers such as the ones referenced above. I like to think of MOF as "service management for the masses."
As the whitepapers describe, MOF can be used to complement ITIL implementations and/or fulfill the minimum critical activities required for ISO/IEC 20000 certification.
Frankly, MOF's biggest obstacle is the big "M" that sits in front of the framework. There is a common misconception that MOF only applies to environments that are heavily invested in Microsoft technologies. The truth is that the best practices in MOF apply to any environment. The guidance is very generic and is not tool-dependent.
The core MOF materials can be downloaded at www.microsoft.com/mof. There is also a MOF community for sharing ideas.
Whether you are already walking down the ITIL path or just starting out, it makes sense to give MOF a read.
