Purpose
This metric shows the percentage of defects that failed the verification and need to be re-fixed. Usually after a
defect is fixed, the fixed defect should be verified. This metric indicates the quality of the fix and the quality of
the code that is being fixed.
Definition
Percentage Fixes Failing Verification = (Number of defects that failed the verification / Total number of defects that
been fixed) * 100
-
