  3. Acceptance sampling plans are not very effective for inspecting small lots of custommade products
  4. Acceptance sampling plans are beneficial when the cost of inspections is high and the resulting loss of passing non-conforming units is not great
  5. Acceptance sampling plans are never as effective at rejecting non-conforming units as 100 percent inspection, even when the inspection process is very tedious
