I've been talking to a lot of clients that want to implement a service-oriented architecture (SOA). Many have been playing around with different implementations and they proudly show me the couple of services they have implemented and say, "What do you think of our SOA?" I usually answer with something along the lines of, "That's a good start," or "This looks like a useful service," or segue into some line of questioning about what they did and what they learned.
