Enterprise Architecture as Strategy: Creating a Foundation for Business Execution by Peter Weill, Jeanne W. Ross, David Robertson
4.0
Very conveniently summarises itself in the last couple of pages: "EA in many companies refers to a detailsed blueprint of systems, data and technology. It is now clear that EA is instead a business vision. EA begins at the top...".
And in a nutshell, that's what the book is about - it's the outcome of a serues of case studies and survey done by Harvard Business School, and their conclusions about what works and what doesn't in developing an enterprise architecture. They identify 4 stages of architecture maturity and discuss how transitions between each can help in each of 4 different models of business enterprise, with the aim of providing business leaders with an understanding of why they should care about EA, and that EA is about business capability not just some "IT stuff" they can ignore.
