As an experienced systems engineer, I thought that this book was pretty basic. It also suffers from the problems that most systems engineering books suffer from. It primarily deals with the development phase and glosses over the activities after that, namely manufacturing, support, and disposal. While I think it might be useful for an introductory course in systems engineering, it doesn't do much for the experienced professional. I feel sorry for students and/or their parents. The authors prices it like a textbook: way out of proportion to what it's worth.
It also has errors that makes you wonder about the authors. For example, it refers to a Boeing 797 Dreamliner. In another case, it gives examples of parameters and then when the authors work out the problem, the parameter values have changed.
It's not a bad book. It is just pretty rudimentary, with a little sloppiness thrown in.
