A test manager is evaluating a test project where the team executed 500 test cases and found 50 defects. Of these, 10 were classified as high severity. The test manager wants to report on the effectiveness of the test design in finding important defects. Which metric is most appropriate to compute and report?

Defect detection percentage (DDP) = (50 / total known defects) × 100

High-severity defect percentage = (10 / 50) × 100 = 20%

Defect density = 50 / 500 = 0.1 defects per test case

Test execution rate = (500 / planned tests) × 100
