That coating! My rating is severe in view of the promise strategy. A good inventory, little technical, historic or algorithmic blah but with a tendency to lengthen the speeches, false "bouncing" between chapters. Questioning is generated, recommendations or at least guidance based on example are given but the heart of the problem is touched upon: the technique is not mentioned that we consider the approximation of the latter with the real need ; this need to be studied so that readers know or go with what objectives, for how long, with what means, etc. The technical elements are not sufficiently extensive (it takes half the book to go a little to the heart) and said vision "strategic" lies more in positioning the reader face his questions in a tree examples successes and failures to position themselves. The content seems rich to the first reading but "Strategy" is too strong for a book "State of Play and questions."
