Summary: Good example
Comment: The best way to learn a new method is to study an example of how the method is used in real life. This the example!
The introduction to this book goes trough the essentials of the Shlaer-Mellor method from the practising users point of view. About every other page you say to yourself: "Ah - yes - that's how it is...". This since Mr. Starr keeps reminding the reader of some of the odds and ends of the Shlaer-Mellor methodology that might be forgotten while you are busy modelling some small corner of your problem. Very useful.
Even more useful is the rest of the book: - a thoroughly worked out example of how an elevator can be controlled. By choosing a system that we all understand how to use, everything becomes real. The mission of the application and the separation of the service domains become very obvious. Although the models in the elevator example are not fully complete, they give you lots of information and insight.
Especially I like the way Mr. Starr documents his problem space using sketches and figures that clearly explains what's going on and also helps out in the process of finding the right classes and relationships in the model. Studying an example like this helps a lot when building your own models.

Summary: A Real Thirst Quencher
Comment: Blues immortal Muddy Waters sang:
Well, if the river was whiskey, and I was a divin' duck
Well, I would dive to the bottom, never would I come up.
While many of us have worked on at least one software development project that could "drive one to drink," we borrow here only the singer's craving, which, like that of the duck, is hard to satisfy. With "Executable UML - The Elevator Project," Mr. Starr gives those who drink from the waters of software development a river that flows from its plentiful and pure headwaters, the Shlaer-Mellor Method. So, "... if the river was an Executable UML modeled system..."
But, before we drink, the book is a case study, and, as such; the author is challenged to build a bridge that meets the needs of the communities on both sides of the river. Viewed from one bank, we need some understanding of Executable UML, the author's objectives, the Elevator problem and the logistics of the tool. From the other bank we need to see the Elevator project artifacts just as they would be produced, without the commentary and critique of a case study.
Mr. Starr constructs that bridge in the following manner. On one bank it is anchored with the Introduction and the Guide to Printing Model Diagrams Technical Note. On the opposite bank the bridge is anchored with the Elevator Application domain analysis model diagrams (the Project Technology BridgePoint repository is also included) and two design documents, the Elevator Project Domain Model and Class Model Descriptions. Each span is constructed from a set of five additional technical notes that describe the system requirements and the approach to fulfilling those requirements.
Now, let's swim into the waters of the system's domain model and taste model based design. Dive to the bottom of the executable Elevator Application model, and drink from the completeness of an unambiguous domain specification. Nudge any object and observe its behavior, savoring the flavor of continuity between the data, state and process model elements, and quench our thirst for verification in the Automated Simulation Exercise. Let's sip translated code generated with the BridgePoint model compiler, which is provided on the demonstration disk. Finally, we relish the ability of the process to be repeated, documented, standardized, managed and optimized.
"Executable UML - The Elevator Project" is an excellent study in what is probably software engineering's best practice. Through the book's comprehensive detail, we can increase our understanding of Executable UML and its fundamental, distinguishing characteristics: separation of subject matter, executable analysis models, implementation through translation and adaptability to a comprehensive engineering process. "... Well, I would dive to the bottom, never would I come up."

Summary: Where's the meat?
Comment: At the price ([price]on my door step), I expected to find something that put all the xUML pieces together, that was worthy of the author's name. What I did find, though, was a book that provided only the most basic information and examples of the topic, and very incomplete at that. You can find xUML white papers freely available on the web which literally contain 100 times more detail and usable technical information. Not only were many parts of the model missing (specifically key service domains), but key elements such as bridge definitions, use cases, etc., were also missing.
Also, there were many self-serving references to both Leon's company and a future book on xUML. Hopefully, THAT book will contain the useful detail that is missing from this one.
For anyone who is considering purchasing this book, wait for the next one and locate the white papers on the web!
