We define direct return on investment (ROI) as the
ratio of reduction in development cost arising from early
issue detection by independent verification and validation
(IV&V) to the cost of IV&V. This paper describes a
methodology to compute direct ROI from readily
available project data. The method is used in a case study
in which IV&V was applied to a mission-critical NASA
software project. For this project, direct IV&V ROI was
10.1, demonstrating that IV&V was cost effective.
