While the book (like most other books of its kind) is a very high-level overview of its subject matter, it discusses many new and compelling ideas that you should find of great use for your own development efforts. Of particular note is the author's discussion of the FURPS+ system, in which functional and nonfunctional requirements are melded into an easily-readable matrix, and all requirements are assigned numerical grades for priority and technical risk. (FURPS+ was developed at HP, where the author works.) And project leaders should pay careful attention to the chapters on project phase metrics, where the author provides average project percentages for the major phases of development.
