Cost of Poor Quality

Cost of poor quality (COPQ) are costs that would disappear if a product or process is perfect.  Void of any waste or errors.

Six Sigma reduces costs and waste by determining the Cost of Poor Quality.  Reducing poor quality is accomplished by:

  • Understanding who your customers are and what is important to them
  • Understanding customer feedback, called the Voice of the Customer, and determining the necessary requirements for your product
  • Prioritizing issues related to your product
  • Determining internal processes and what causes variation
  • Determining what causes defects
  • Developing ways to address the defects
  • Developing metrics to standardize and measure the changes made in the process
