Query: It is a field research book and not practical

This is a SOA introductory book on concepts, design and technology. It is long winded and repetitive. The content of the book is based on industry research and not the author's experience in SOA. In some parts of the book the author encourages forward thinking. At the same time, the author discourages excessive forward thinking and upfront design. If the SOA project is run like an agile project, many of the problems captured in this book won't be an issue. This book will confuse for those who are new to SOA.
