Description du produit
Revue de presse
“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
Présentation de l'éditeur
“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

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...
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.
The authors maintain that the real economic value of high quality software is not the cost to fix defects, but rather:
* the reduced likelihood of canceled projects
* the reduced risk of litigation
* shortened development schedules
* lower development costs
* reduced warranty costs
* increased customer satisfaction
This book addresses:
* What is software quality and how do we define its value?
* How can we estimate and measure software quality?
* How can software defects be prevented?
* How can we find and remove defects before testing?
* What are effective ways to test software and measure its effectiveness?
* What is the current state of post-delivery software defects?
* How do projects of various characteristics (low, average and high-quality) compare?
* How can technical debt be addressed from a business value perspective?
You will find a multitude of data from projects in a variety of industries, at various levels of quality, and at various levels of practice maturity. You will see by the numbers which project approaches work and which ones don't work very well.
By reading this book, you will gain insight not only into the current state of software quality, but you will also learn about measurement and metrics of software. These are critical things for any software quality professional to learn. In fact, after reading this book, you will know more about software measurement than 95% (that's my estimate) of testers and QA professionals.
I highly recommend this book, not only as a guide for software quality efforts, but also a benchmark for your own efforts.
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.
