How do we achieve CoC enterprise integration?

Enterprise integration is achievable in the same manner that all large complex systems are successfully completed. Whether building airlines, building, or large complex systems, all successful projects share an architecture-based development process. Thousands of years of experience have resulted in the standardized architectural practices. There are two primary foci in the development of the CoC Enterprise Architecture:

1. specifying customer and corresponding technical system requirements; and
2. providing a common means of communication for developers and customers to use as they work to evolve the system.

So how do architectures help us to achieve enterprise integration?
