Business SOA governance is about the long term transformation of IT to align with the business. This means establishing a clear business architecture and then creating a business SOA governance group who will ensure that vision is followed. This is a powerful group and needs to act in the same way as a judiciary. Their role is not to undertake the work but to enforce the boundaries and rules.

Composite Software offers a new level of granularity when compared to SaaS (Software as a Service). Composite Software is about enabling "right-sourcing", i.e. move (or keep) arbitrary small or large elements of functionality wherever it is the most cost effective to operate them, not just entire systems. Economically, "right-sourcing" is far more efficient than "outsourcing" and SaaS. The goal of this book is start by understanding today’s software construction processes and technologies and explore why and how it should be evolved to support core composition mechanisms.
