What is defect leakage & formula?

Question

I have some idea about defect leakage. Can anyone let me know what is the correct definition or term of the defect leakage formula?

Shivangi Mehta · Accepted Answer

Defect leakage formula is defined as -

Number of Defects slipped / (Number of Defects raised - Number of Defects withdrawn)

Example: In production the customer raises 21 issues, during your tests 267 Issues were reported but there were 17 invalid defects (e.g. because of wrong tests, mistake by tester, error in test environment...)

Then your Defect Leakage Ratio would be:

[21/(267-17)] x 100 = 8.4%
