Twenty Cells Certify a Thousand Punnets

A single-sampling germination acceptance plan for seedling lots, and the verdict that lands after the sale

A research poster from the School of Continuous Improvement specifies a single-sampling attributes plan for the seedling punnets a garden-centre chain receives, drawing twenty cells from each incoming lot and accepting on one failure to germinate. Across 316 lots over fourteen months the plan discriminates as designed, at a producer's risk of 3.6 per cent and a consumer's risk of 10 per cent at eighteen per cent nonconforming, but returns its verdict a median of twenty-one days after receipt against a median shelf residence of eight, so 91.5 per cent of lots are certified after the last punnet has been sold.
