Six Sigma reduces costs and waste by determining the:

Cost of poor quality

The sum of internal and external failures. It is measured differently depending on the industry

Cost of poor quality

The sum of internal and external failures. It is measured differently depending on the industry.

Cost of poor quality

The total cost when you add up the cost of all the prevention and inspection activities you are going to do on your project.

Cost of quality

This analysis is looking at how much your quality activities will cost, versus how much you will gain from doing them.
