I am a DBA by profession and never been part of any development or testing activity. It will be great if you can help me with the calculation
Calculate defect leakage in design where there are:
This is one of those questions where there is no absolutely correct answer.
If you are looking for all defects that leaked from design to test, then there are 20 because the defects captured (and presumably corrected) during code review don't count towards that number.
If you are looking for defects that were not captured and fixed during design, it would be the 10 found during code review, and possibly some or all of the 20 found in test depending on whether their root cause relates to design flaws.
Either way, this metric isn't particularly effective because what ultimately matters is how many defects leak to production, and how much they impact the customers.
