How is the "Defect Removal Efficiency" metric typically calculated?
- (Defects fixed / Defects reported) x 100%.
- (Defects found by testers / Defects found by users) x 100%.
- (Defects found post-release / Total defects) x 100%.
- (Defects found pre-release / Total defects) x 100%.
"Defect Removal Efficiency" (DRE) metric measures the effectiveness of the testing process. It's calculated as the ratio of defects found before release (by the testing team) to the total defects (found both before and after release). A higher DRE indicates a more effective testing process.
