Software Quality Control Interview Question:

Tell me what is Defect Rejection Ratio (DRR) and Defect Leackage Ratio (DLR)?

Submitted by: Administrator

DRR = # of Defects Rejected/Tester to assess the tester performance

DRR = # of Defects Rejected/module to assess the module complexity

DRR = # of Defects Rejected/Team/Project to assess the team performance.

and

DLR = # of Defects uncovered/Tester

DLR = # of Defects uncovered/Module

DLR = # of Defects uncovered/Project

( Uncovered- Defects missed out by the testing team)
