Utility, Warranty, Confusion, Mayhem

The new ITIL v3 Service Strategy book discusses a couple of interesting new concepts. The "utility" (fit for purpose) and "warranty" (fit for use) when looking at the "value creation" of a service.

To me, when I look at these terms and the surrounding text it seems to be a re-work of the Effectiveness (do the right thing - utility) and Efficiency (do things well - warranty) concepts that we’ve been familiar with under ITIL v2.

I wonder if anyone else is seeing basic concepts that we've grown used over the years reworked into something that is certainly different and potentially more confusing?
