Decoupling the Client and Service Platforms
The realization seems to be hitting the masses that Service Oriented Architecture isn't just about the Services, rather it is about the consumption of those services. Dare I say, it is about the clients (and the services).
The SOA programs that I've seen stall out typically were because they failed to identify the composite applications that would consume the services. It sounds rather obvious - but it isn't about building or buying services. Value is created when business people use clients that leverage the services. I guess that's one of the reasons why I always try to call this paradigm 'Client-Service Computing', rather than SOA.
