Once again, Glass has proven that he belongs in the software engineering pantheon along with Tom DeMarco, Gerry Weinberg, and Steve McConnell.
This book will open your eyes. If you work in the field, you'll never think about your livelihood the same way again.
If you take only one thing away from this book, remember this: don't blindly trust what the advocates of the latest methodology are saying, whether it be OO, XP, RUP, or UML, without some substantive evaluative research backing them up. Glass makes compelling arguments as to why the software industry has fallen easy prey to the hucksters and snake-oil salesmen.
