"""Since software quality assurance is still an issue in software organizations, a deep understanding of the subject itself, as well as of methods for effectively implementing software quality, is crucial for both software managers and practitioners. Comprehensive books like this one can help readers to get into the field. However, O¿Regan¿s book is more than just an introduction. It also serves as a good reference for people who want to step into the subject practically, and for those who want to find out about the quality measures that could best fit their organizations...I recommend this book to those interested in learning how software quality helps increase software companies¿ productivity."" --Computing Reviews"
