wht is Defect removable efficiency..

Answer / kris

The DRE is the percentage of defects that have been removed
during an activity, computed with the equation below. The
DRE can also be computed for each software development
activity and plotted on a bar graph to show the relative
defect removal efficiencies for each activity. Or, the DRE
may be computed for a specific task or technique (e.g.,
design inspection, code walkthrough, unit test, 6 month
operation, etc.). [SQE]
Number Defects Removed
DRE = –—————————————————— * 100
Number Defects At Start Of Process

DRE=A/A+B = 0.8

A = Testing Team ( Defects by testing team )
B = customer ( " " customer )

if dre <=0.8 then good product otherwise not.

ok, bye....
