Query: No proof !!!

Throughout the book the author discusses on the same stuff repeatedly.....as multiple parts and chapters. It is a collection of Web services articles narrates the same story of how Web services technology will impact their business strategies and organization. The author written this book exploding a business article and explored his own meaning of Web services oriented architecture.I am bit disappointed after reading the book as the contents does not make a case for a manager..... why you would ever build or use web services, what are its benefits and known issues of Web services, etc. Nevertheless, if you are looking for answers what web services really are (e.g. when to use them, etc.), this book doesn't provide those answers. Think twice before you buy...you may save your money.
