Acceptance sampling

A statistical method to decide whether a lot is accepted or rejected based on a sample instead of 100% inspection.

Definition and context

Acceptance sampling balances risk, speed, and inspection cost when full inspection is not practical.

Sampling plans are typically selected from AQL levels and agreed between buyer and supplier before production.

How acceptance decisions are made

Inspectors draw a sample size based on lot quantity and inspection level, then compare defects against accept/reject thresholds.

The method protects both parties by making acceptance criteria explicit before shipment decisions.

Operational impact

Consistent sampling rules reduce arguments at final inspection and improve predictability in release decisions.

It is most commonly applied during Final random inspection when shipment readiness is evaluated.

Where this term fits in the workflow

Terms used when teams decide what to inspect, how much to sample, and whether a lot can ship.
