“Whether consulting, working on projects, or teaching, whenever I need credible, detailed, relevant metrics and insights into the current capabilities and performance of the software engineering profession, I always turn first to Capers Jones’ work. In this important new book, he and Olivier Bonsignour make the hard-headed, bottom-line, economic case, with facts and data, about why software quality is so important. I know I’ll turn to this excellent reference again and again.”
—Rex Black, President, RBCS
Poor quality continues to bedevil large-scale development projects, but few software leaders and practitioners know how to measure quality, select quality best practices, or cost-justify their usage. In The Economics of Software Quality, leading software quality experts Capers Jones and Olivier Bonsignour show how to systematically measure the economic impact of quality and how to use this information to deliver far more business value.
Using empirical data from hundreds of software organizations, Jones and Bonsignour show how integrated inspection, structural quality measurement, static analysis, and testing can achieve defect removal rates exceeding 95 percent. They offer innovative guidance for predicting and measuring defects and quality; choosing defect prevention, pre-test defect removal, and testing methods; and optimizing post-release defect reporting and repair.
This book will help you
- Move beyond functional quality to quantify non-functional and structural quality
- Prove that improved software quality translates into strongly positive ROI and greatly reduced TCO
- Drive better results from current investments in Quality Assurance and Testing
- Use quality improvement techniques to stay on schedule and on budget
- Avoid “hazardous” metrics that lead to poor decisions

A Great Resource for Quantifying Software Quality,
This review is from: The Economics of Software Quality (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.

An encyclopedia of Software Quality Data,
This review is from: The Economics of Software Quality (Hardcover)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... Read more
