Assume that each defect in gathering requirements allowed to go to customers costs $10, 000, and that the corresponding costs for design defects and coding defects are $1, 000 and $100, respectively. Also, assume that current statistics indicate that on average ten new defects come from each of the phases. In addition, each phase also lets the defects from the previous phase seep through. What is the total cost of the defects under the current scenario? If you put a quality assurance process to catch 50% of the defects from each phase not to go to the next phase, what are the expected cost savings?
