Definition and context
Sampling plans balance risk, speed, and cost by checking representative units instead of every piece.
A strong plan prevents arbitrary inspection decisions and keeps supplier-buyer expectations aligned.
Core elements
Plans typically define inspection level, sample size code, acceptance/rejection numbers, and defect classification.
They should also specify handling rules for borderline results and repeat sampling conditions.
Risk alignment
More stringent plans are applied to high-risk products, new suppliers, or unstable processes.
As supplier capability improves, teams may adjust strategy while preserving customer protection.
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.
