gud question buddy...

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)

Hi,What do you mean by "Tester to assess the performance" in the denominator of the equation Defect Rejection Ratio = No of defects rejected / Tester to assess the performance.

DEFECT REJECTION RATIO (DRR)

DRR measures issues that were raised that ultimately had no impact on product quality.  This could easily be considered a measure of wasted effort and an opportunity for improvement. 
 

DRR = # of defects rejected per tester; (assess tester performance)
DRR = # of defects rejected per module; (assess module complexity)
DRR = # of defects rejected per team or project; (assess overall performance)

DEFECT LEAKAGE RATIO (DLR)

DLR measures issues that were not identified during the test phase.  Again, this is another opportunity for improvement. 

DLR = # of defects missed per tester; (assess tester performance)
DLR = # of defects missed per module; (assess module complexity)
DLR = # of defects missed per team or project; (assess overall performance)
