Supply chain homework | Operations Management homework help

Is quality free? Or does quality have a cost? What about the cost of poor quality?  How much does that cost? Can you think of a time when you bought a product and it was defective?  What did you do?  How did it make you feel about the firm who made the product?  Think about your actions in that scenario and the costs the company had to incur to “make it right.”

Cost of quality (COQ) analysis was developed in the 50s to help clarify the cost impacts of poor conformance quality. COQ identifies and assesses four major cost categories, which are prevention, appraisal, internal, and external costs.

  • Prevention costs are incurred due to efforts used to prevent poor quality from occurring in the first place. 
  • Appraisal costs are basically the costs associated with incoming material inspections, product and process inspections, inspection staff salaries, test equipment, and development of test procedures. 
  • Internal failure costs result when a defect is detected before the product is shipped.  These costs include the cost of salvage and rework.
  • Finally, if a defect does occur, and it happens to be discovered by the customer, the firm incurs external failure costs due to complaint settlements, loss of customer goodwill and future sales, returned materials, warranty work, and field service or repairs.
