| Abstract: |
In Part I - The Foundation, we showed how Service Oriented Architecture can establish better separation between major enterprise components, and enable inherently more adaptable back end applications. Part II - The Bridge discussed how components could be identified and linked clearly to the business world, so providing a simple bridge between the business and the IT system. In this report we examine how these same concepts can enable effective collaboration intra and inter enterprises. The key to collaboration is federation - a concept that enables loosely-coupled but effective integration - through "higher-level" services. We recommend this approach because federation as the basis for collaboration and integration can enable much more rapid business evolution and responsiveness than other approaches.

| Backgrounder: |
In this report we assert that service federation is not just about gluing together what's there already; it's about seeing federated services as the basis for future systems architecture, from the small-grained to the very large-grained services. When we said that federation is about creating an environment where common services are made available for use in conjunction with others, we omitted the context, which is that of flexible, evolvable, low-maintenance service provision, so that the business's time-to-market goals are met.
