Editorial Reviews


“This book provides the best treatment on the subject of economics of software quality that I’ve seen. Peppered with valuable industry data, in-depth analysis, empirical methods for quality improvement, and economic analysis of quality, this book is a must-read for anyone who is interested in this subject. With the many real-life and up-to-date examples and stories linking software quality to daily-life activities, readers will find this book an enjoyable read.”

–Stephen H. Kan, Senior Technical Staff Member and Program Manager, Software Quality–IBM Systems and Technology Group, and author of Metrics and Models in Software Quality Engineering


“Finally, a book that defines the cost and economics of software quality and their relationship to business value. Facts such as the inability of testing alone to produce quality software, the value of engineering-in quality, and the positive ROI are illustrated in compelling ways. Additionally, this book is a mustread for understanding, managing, and eliminating ‘technical debt’ from software systems.”

–Dan Galorath, CEO, Galorath Incorporated & SEER by Galorath


“Congrats to Capers and Olivier as they release their relevant, extensive, and timely research on the costs of defects in today’s software industry. The authors don’t stop with the causes of defects; they explore injection points, removal, and prevention approaches to avoid the ‘technical mortgage’ associated with defective software products. In today’s ‘quick-to-market’ world, an emphasis on strengthening the engineering in software engineering is refreshing. If you’re a software developer, manager, student, or user, this book will challenge your perspective on software quality. Many thanks!”

–Joe Schofield, Sandia National Laboratories; Vice President, IFPUG; CQA, CFPS, CSMS, LSS BB, SEI-certified instructor


“This masterpiece of a book will empower those who invest in software–and the businesses and products that depend on it–to do so wisely. It is a groundbreaking work that rigorously applies principles of finance, economics, management, quality, and productivity to scrutinize holistically the value propositions and myths underlying the vast sums invested in software. A mustread if you want to get your money’s worth from your software investments.”

–Leon A. Kappelman, Professor of Information Systems, College of Business, University of North Texas


“Capers Jones is the foremost leader in the software industry today for software metrics. The Economics of Software Quality is a comprehensive, data-rich study of challenges of quality software across the many application domains. It is an essential read for software quality professionals who wish to better understand the challenges they face and the cost and effectiveness of potential solutions. It is clear that much research and thought has been put into this.”

–Maysa-Maria Peterson Lach, Senior Principal Software Engineer, Raytheon Missile Systems


“In no other walk of life do we resist the necessity and validity of precise, rigorous measurement, as software practitioners have so vigorously resisted for more than fifty years. Capers Jones took up the challenge of bringing sanity and predictability to software production more than three decades ago, and now with Olivier Bonsignour, he brings forth his latest invaluable expression of confidence in applying standard engineering and economic discipline to what too often remains the ‘Wild, Wild West’ of software development.”

–Douglas Brindley, President & CEO, Software Productivity Research, LLC

More About the Author

Capers Jones is vice president and Chief Technology Officer of Namcook Analytics LLC. His web site is www.Namcook.com. Namcook Analytics designs and builds advanced software risk, quality, and cost prediction tools.

Capers Jones is working on his 15th book, The Technical and Social History of Software Engeering, to be published by Addison Wesley in 2013.

Capers Jones was born in St. Petersburg, Florida. He later attended the University of Florida in Gainesville.

While working for the U.S. Public Health Service as an editor, he had an opportunity to learn programming. He then became a programmer/analyst and worked on software applications for hospital administration.

In 1965 he moved to corporate industry as a systems analyst for Crane Company. Two years later he joined IBM in Boulder, Colorado. At IBM he became interested in software estimating, and developed a proprietary estimating tool for IBM with Dr. Charles Turk. After both management and research positions in IBM, he was invited to join a new software laboratory being created by the ITT Corporation in Stratford, Connecticut. As assistant director of measurements he was part of the company's first software measurement program.

In 1984 he founded Software Productivity Research (SPR), and began to develop commercial software estimating tools. SPQR/20 in 1984 was the first commercial estimating tool based on function point metrics. Allan Albrecht, the inventor of function points, joined SPR after retiring from IBM. While at SPR Allan developed the first certification exam for function point analysis.

Capers first software management book was Programming Productivity: Issues for the Eighties, published by the IEEE Computer Society Press in 1979. He has now published more than a dozen books on software management topics including Estimating Software Costs, 2nd edition, McGraw Hilll 2007; Applied Software Measurement 3rd edition, McGraw Hill, 2008; and Software Engineering Best Practices, McGraw Hill, 2010. His next book will be The Economics of Software Quality with Jitendra Subramanyam as co author. It will be published by Addison Wesley later in 2011.

In 2006 Capers switched genres and published a history book entitled "The History and Future of Narragansett Bay." This book covers the geology, ecology, and settlement of the Bay region from before the last ice age through modern times. It also discusses the Native Americans who lived and still live near the Bay, and the settlement history of 18 Bay towns. Economic and political topics are also included.

His current research topics include early, high-speed sizing of software applications; improving software quality control, and improving software risk and value analysis prior to funding major applications. He is also working on expanding function points to included "data points" for sizing data bases and "value point" for integrating financial and non-financial value topics.

Format: Hardcover
In this book, authors Capers Jones and Olivier Bonsignour quantify the factors that influence software quality and provide information for people to gain insight into how their projects might compare to others. The measurements in this book are based on thousands of software projects.

One of my frequent complaints about the software industry is that we just don't measure very many things. However, thankfully there are people like Jones and Bonsignour that do have a rich source of metrics from enough projects that we can learn from them.

Capers Jones has long been considered the source for software quality metrics. To me, Capers is the "numbers guy" of our profession. With over 40 years in the field, Jones has a wealth of information he has maintained and published over many years.

Olivier Bonsignour is responsible for Research & Development and Product Management in a continual effort to build the world's most advanced Application Intelligence technology. Prior to joining CAST, Mr. Bonsignour was the CIO for DGA, the advanced research division of the French Ministry of Defense.

For example, the authors state that "high quality levels are invariable associated with shorter-than-average development schedules and lower-than-average development costs." This finding is based on over 13,000 projects between 1973 and today.

Capers Jones and Olivier Bonsignour have authored a very useful book that will help the software industry make more objective decisions and improve the economic outcomes of software delivery organizations. This book is loaded with data, benchmarks and cause-and-effect relationships for reasoning about how to improve software quality. It is not an easy read because it goes both deep and broad across the diverse contexts of software domains and across the life-cycle practices of software development. This book is a great place to start when looking for credible and objective benchmark data to build a business case or defend a proposal for improving software quality or productivity.

The economics of software quality is an attractive topic all by itself. However, the book delivers unexpected value on two other fronts. First, the presentation and discussion of substantial data provides an educational framework for quantitative reasoning with enlightening discussions on cause and effect as well as cautions on potential misinterpretation. Second, the well-integrated history lessons throughout give the reader a good feel for the improvement trends, or lack of improvement trends, across the software industry.

Decades of experience, compiled into an encyclopedia of facts and figures. Well worth the price.

This book is a a precious and amazing piece of work. It includes hundreds of statistics and real world metrics, organized by project type, project size, technology, methodology, etc...
Statistics range from defect density to common quality tools and processes defect removal efficiency.
I do not know any source of information that come even close to this one.
Precious corpus for anybody dealing with Software quality and outsourcing contracts.
And a great book for anybody dealing with software in general !
Expected all my expectations on the subject...
