Requirements
1. Prepare a Cost of Quality (COQ) report. In addition to calculating the total costs of each category, calculate the percentage of each COQ category of the total COQ.
2. Why would the variable repair cost at the customers' homes generally be higher than the "in factory" rework cost?
3. How can use of the COQ report lead to improvements in the production process or in the quality of the product itself?
