Quality assurance is usually waste itself, cause it’s just hiding that the process isn’t reliable by itself.

When you find a defective product, the production line usually stops and put in a safe condition, the root cause needs to be troubleshooted and found, and the defect corrected and/or repaired or replaced due to normal/abnormal wear and tear, something broke, someone didn’t follow the established process, dirty environment, etc. Also, replacement parts may need to be procured (in Hawaii, we often fly in urgently needed parts). The Worst case senario would be if the defective products were REJECTED by the CUSTOMER!
