What Does it Cost You to Fix a Defect?

Joanna Rothman writes, "Although I polled many people, only one person knew what it cost his company to fix a defect. If you're not sure either, here is an estimation technique to measure that cost: In system test, when people are 100% dedicated to finding and fixing defects, count the number of fixes. You know how many people (developers, testers, and anyone else) worked on the project, and you know the duration of system test. The average cost to find and fix a defect is: Average cost to fix a defect = (Number of people * number of days/Number of fixed defects) * cost per person-day."
