For example, consistency in the programming model used to expose services and exploit references to other services, consistency in the way you describe the assembly of components in your solution and consistency in the way that policy is applied to control quality of service concerns. The SCA model applies regardless of what implementation or communcation technology you use. In you're scenario how do the multiple contributors implement services and communicate with the ESB? Do services only ever communicate via the ESB? Regards Simon
