I learned a new (for me) buzzword recently when a journalist asked me about "Service Assurance". Sounds like a new spin on an old idea: the single view of a service. This is yet another techno-geek wet dream.
The IT Swami long ago had the vision of the three legs (or castors) of the IT Management chair: Service, Governance and Assurance.
Service is well established now, thanks to ITIL - at least in our minds if not so much in practice yet.
