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 Jitendra Subramanyam 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 Subramanyam show how integrated inspection, 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 Prove that improved software quality translates into strongly positive ROI and greatly reduced TCO Drive better results from current investments in debugging and prevention Use quality techniques to stay on schedule and on budget Avoid "hazardous" metrics that lead to poor decisions Important note: The audio and video content included with this enhanced eBook can be viewed only using iBooks on an iPad, iPhone, or iPod touch.

Software development has been a troubling since it first started. There are seven chronic problems that have plagued it from the beginning: Incomplete and ambiguous user requirements that grow by >2% per month. Major cost and schedule overruns for large applications > 35% higher than planned. Low defect removal efficiency (DRE) Cancelled projects that are not completed: > 30% above 10,000 function points. Poor quality and low reliability after the software is delivered: > 5 bugs per FP. Breach of contract litigation against software outsource vendors. Expensive maintenance and enhancement costs after delivery. These are endemic problems for software executives, software engineers and software customers but they are not insurmountable. In Software Development Patterns and Antipatterns, software engineering and metrics pioneer Capers Jones presents technical solutions for all seven. The solutions involve moving from harmful patterns of software development to effective patterns of software development. The first section of the book examines common software development problems that have been observed in many companies and government agencies. The data on the problems comes from consulting studies, breach of contract lawsuits, and the literature on major software failures. This section considers the factors involved with cost overruns, schedule delays, canceled projects, poor quality, and expensive maintenance after deployment. The second section shows patterns that lead to software success. The data comes from actual companies. The section’s first chapter on Corporate Software Risk Reduction in a Fortune 500 company was based on a major telecom company whose CEO was troubled by repeated software failures. The other chapters in this section deal with methods of achieving excellence, as well as measures that can prove excellence to C-level executives, and with continuing excellence through the maintenance cycle as well as for software development.

“Capers Jones has accumulated the most comprehensive data on every aspect of software engineering, and has performed the most scientific analysis on this data. Now, Capers performs yet another invaluable service to our industry, by documenting, for the first time, its long and fascinating history. Capers’ new book is a must-read for every software engineering student and information technology professional.” — From the Foreword by Tony Salvaggio, CEO and president, Computer Aid, Inc. Software engineering is one of the world’s most exciting and important fields. Now, pioneering practitioner Capers Jones has written the definitive history of this world-changing industry. Drawing on several decades as a leading researcher and innovator, he illuminates the field’s broad sweep of progress and its many eras of invention. He assesses the immense impact of software engineering on society, and previews its even more remarkable future. Decade by decade, Jones examines trends, companies, winners, losers, new technologies, productivity/quality issues, methods, tools, languages, risks, and more. He reviews key inventions, estimates industry growth, and addresses “mysteries” such as why programming languages gain and lose popularity. Inspired by Paul Starr’s Pulitzer Prize–winning The Social Transformation of American Medicine, Jones’ new book is a tour de force—and compelling reading for everyone who wants to understand how software became what it is today.
