The hype amongst suppliers with a vested interest in Service Oriented Architecture grows daily.
Intuitively its a great idea. Turn your organisation into a set of services that can be used and stitched together to form business processes which in turn are exposed to front and back office staff, business partners, agents, customers via direct channels etc etc. These services are loosely coupled to the existing IT applications so can be maintained independently. Users only effectively see one simple system. Brilliant!
