This article discusses a Supply/Demand oriented SOA architecture - driving the SOA from a business perspective.
"Many organizations are now undertaking development of service oriented architectures, but the probability is that most will result in sub-optimal implementation.

In this report we provide explicit process guidance on how to develop the right SOA for your business."
