Defect Analysis over Multiple Release Versions of a Semiconductor Software System

Demonstrating software reliability across multiple software revisions has become essential to end users of an end point detection system used in the semiconductor industry. This would enable them to make informed decisions of upgrading software versions without making significant impact to their current established processes. We show how one can use standard defect data normally collected in any software development organization to demonstrate reliability trends. We provide evidence of reliability maintained across the different versions and that continuous defect fixes increased software reliability over time.
