Difference between defect leakage and defect control

Question

Accepted Answer

Defect leakage is when defects are not identified during testing and are found by users, while defect control is the process of managing and preventing defects.

Defect leakage occurs when defects are missed during testing and are discovered by users after the product is released.
Defect control involves implementing processes and strategies to identify, track, and prevent defects throughout the development lifecycle.
Defect leakage can result in negative user experiences, loss of credibility, and increased costs for fixing defects post-release.
Defect control helps in ensuring that defects are caught early in the development process, reducing the likelihood of defects reaching the end-users.
Examples of defect leakage include critical bugs in a software application that were not identified during testing and are reported by users after the release.
Examples of defect control measures include implementing code reviews, automated testing, and continuous integration to catch defects early in the development cycle.
