Business Relationship Management is 'missing'
ITIL V3 was supposed to provide better support for ISO/IEC 20000, yet it would appear that "Business Relationship Management" has been almost forgotten in the guidance.
The Service Strategy book does briefly refer to the concept of "Business Relationship Management" and it has also been listed as a Process/Function in the V3 glossary, yet it has not been formally or properly covered. Did the Strategy authors forget about this one...?
The standard covers Business and Supplier Relationship Management as well as Service Reporting in relation to Service Level Management. It would seem that ITIL V3 is not consistent enough with the ISO/IEC 20000 in this regard.
