Defect Removal Efficiency (DRE)

Defect Removal Efficiency (DRE)

DRE is a measure to detect defects before delivery.It is calculated as a percentage of the defects identified and corrected internally with respect to the total defects in the complete project life cycle. Thus, DRE is the percentage of bugs elimiated by reviews, inspections, tests etc.

Here is an interesting Defect Removal Efficiency calculator by Harvey Roy Divinagracia:

Devankur,

Thanks for the wealth of info you've provided on the site. I check it often for new content.

I work at a small company where we standardizing the QA dept's processes. We are currently looking for a relatively cheap tool that is similar to Test Director in functionality. Basically we need a Test case management tool that is not going to cost an arm and a leg.

Any suggestions.

Thanks,
Danish.
