If you do not have a copy of a UML tool (such as Rational Rose or Microsoft Visual Modeler) you will be wasting your money on "Instant UML." But if you are comfortable with Grady Booch's methodologies and have an extensive background in software engineering (having read Steve McConnell's "Rapid Development" book, for instance), then you may find "Instant UML" useful as a reference. If you are a complete beginner to UML and looking to satisfy your curiosity about UML, trying to understand this book will be a maddening and futile exercise, because of the overly concise and highly technical quality of the writing. Although the jacket of the book states that you can "Learn how to document the object-oriented development process," it is clearly the case the Muller expects the reader to know a significant amount about UML before beginning. Because this book is marketed for the UML beginner, but clearly is not suitable for the beginner, this book is NOT RECOMMENDED.
