The article discusses how using multiple sampling plans can help quickly identify products with extreme quality, whether very good or very bad. There are two types of multiple sampling plans: m-stage sampling, where a set number of sample portions are evaluated before making a decision, and sequential sampling, which allows for continued sampling until a final decision is made. The article compares the performance of multiple sampling plans to single sampling plans, focusing on key measures like the operating characteristic function and average cumulative sample size.
