Defect injection is equal to No of defect created in development effort(developer total hrs spent). Defect detection is “confirmed defects detected” in defined period of time. Defect discovery(detection) rate is equal to no. of defects found in testing effort (Tester total hrs spent) Defect Density = No. of bugs / Developer effort (not tester) Bug Density = Defects in Releases / Total Story Points (Where “Story Points” are complexity points, [ Read More ]
