Acceptance Sampling: LTPD and AQL

Acceptance sampling is an important aspect of statistical quality control. It originated back in World War II when the military had to determine which batches of ammunition to accept and which ones to reject. They knew that they couldn’t test every bullet to determine if it will do its job in the field. On the other hand, they had to be confident that the bullets they’re getting will not fail when their lives are already on the line. Acceptance sampling was the answer – testing a few representative bullets from the lot so they’ll know how the rest of the bullets will perform.
