I've been looking for some good, clear case studies on the Model-Driven Architecture approach as used in Industry and in particular how this works with developng systems with the SOA pattern.  I am currently reading this book on Real-Life MDA: Solving Business Problems with Model Driven Architecture which hints on some process to include MDA in the life cycle. 

Here is the full abstract:

Model Driven Architecture (MDA) is a new approach to software development that helps companies manage large, complex software projects and save development costs while allowing new technologies that come along to be readily incorporated. Although it is based on many long-standing industry precepts and best practices, such as UML, it is enough of a departure from traditional IT approaches to require some "proof of the pudding." Real-Life MDA is composed of six case studies of real companies using MDA that will furnish that proof. The authors' approach MDA projects by describing all aspects of the project from the viewpoint of the end-users—from the reason for choosing an MDA approach to the results and benefits. The case studies are preceded by an introductory chapter and are followed by a wrap-up chapter summarizing lessons learned.
