AQL is not a product specification: define defects before inspection
Build a usable inspection brief by defining critical, major and minor defects, sample rules and acceptance decisions before the goods are checked.
Buyers sometimes ask for an “AQL inspection” as if the term defines acceptable quality. Sampling rules help decide how many units to inspect and how results are evaluated, but they do not explain what counts as a defect. Without an agreed defect list and product specification, two inspectors can examine the same item and report different conclusions.
Start from the approved requirement
The inspection brief should identify the product revision, approved sample, measurements, materials, workmanship and packaging requirements. Do not ask an inspector to reconstruct the order from scattered messages. If a requirement cannot be checked with the available method, say so before the visit.
Classify defects for the real product
Critical, major and minor categories should reflect safety, legal, functional and commercial consequences for that product and market. A cosmetic mark may be minor on an industrial component but major on a premium retail item. Obtain specialist input where classification requires technical or regulatory judgment.
Define the sampling and decision rule
State the lot size, sampling standard, inspection level and acceptance limits agreed for the project. Also explain how mixed models, colours or sizes are represented. An overall pass can hide a severe problem in a small variant if the sampling plan does not account for the assortment.
Plan what happens after the report
A failed result does not automatically decide whether goods are reworked, re-inspected, accepted with concession or cancelled. The buyer should review defect evidence, quantity affected, corrective proposal and contractual rights. Record the decision and any conditions for release.
Decision checklist
- Approved specification and sample
- Product-specific defect examples
- Critical, major and minor categories
- Lot size and sampling method
- Variant representation
- Decision process after pass or fail
