Abstract

The question of how to determine an appropriate sample size n for an attribute control chart has been the subject of a number of research papers. Unfortunately, this stream of research has neither produced tools that are easy to understand, nor it does provide a manager with a good understanding of the tradeoffs involved by the sample size decision. In this paper, we propose a practical method of determining an appropriate sample size that allows the manager to evaluate the tradeoffs between the ability to detect an out-of-control process, the probability of generating a “false alarm” and the sample size (which will determine the cost of implementing the sampling plan).
