LKP Consulting GroupPresents The Real Cost of Software Defects 1 Quantify and Mitigate Risk introduced in Technology Projects and Increase Project Efficiency through a structured QA organization by applying a formal and consistent QA and Testing Framework.Objective To Identify. The Real Cost of Software Defects 2 . Barry Boehm. has published several studies over nearly three decades that demonstrate how the cost of removing a software defect grows exponentially for each downstream phase of the development lifecycle in which it remains undiscovered [2]. economy. alone. According to the CTO of one software development organization. one of the industry's leading experts on software quality. Boehm's results have been confirmed in a number of subsequent studies [3]. a bug that costs $1 to fix on the programmer's desktop costs $100 to fix once it is incorporated into a complete program. The same NIST study estimated that software defects cost the U. $60 billion per year [4]. The Real Cost of Software Defects 3 . another major research project conducted recently by the United States Department of Commerce. fully 80% of software development dollars are spent correcting software defects. Since the original study. Further.The Real Cost of Software Defects The longer a defective application evolves the more costly it is to repair. National Institute of Standards and Technology showed that in a typical software development project.S. and many thousands of dollars if it identified after the software has been deployed in the field [1].
