As we have been working with clients, we have to introduce these ideas around doing just enough validation so consumers really should be consuming only those bits of a provider they really want and intend to process rather than naively reflecting the entire service within each individual consumer. And if we can bring to the surface some of these real contracts that exist between service providers and consumers, how a service is actually been consumed here and now; and if we have insight into that process then we are better positioned to plan and mange the overall evolution of that system, so what we are talking about really just enough validation but also introducing a form of contract that really allows the consumers to express what is they really want of a system, what is this functionality they want to exploit and what they expect those contracts that the service providers exposes, what they expect those contracts consisted and once we can have insight into these contracts then I think we are better placed to evolve the provider independently from the consumer.
