AQL is not a zero-defect guarantee
What this resource changes in your next decision, and the evidence behind it.
Takeaways
- An AQL defines the sampling plan and the acceptance limit: it accepts a defined defect rate by design.
- Inspection is only as early as the process allows; incoming, first-article and in-process checks stop defects at the cheapest stage.
- Write the inspection level, sampling plan and test items into the order, or inspection is whatever the line decides on the day.
The problem it answers
Evidence and limits
Based on our inspection records and on how AQL 2.5 is normally quoted for jewellery. The right level depends on the defect class and the sales channel.
