Below are the newly prepared quality costs for the last two quarters:
Last quarter last year: $312,000 $524,000
First quarter this year:
Scrap and Rework: $624,000
Customer returns and warranty: $204,000
Total: $836,000
In spite of agreeing to your request to employ further inspection staff from January to increase finished product inspection to 100 percent, you will see that overall quality costs have shown no significant change. I look forward to receiving your comments on this.
Discuss the issues raised by the above memorandum:
