Abstract : The sampling inspection plans discussed are applicable only to a production process in which the units of product are classified as either defective or nondefective. These plans are designed to set a prescribed upper limit to the average outgoing quality of the final product entering into consumption channels. This is accomplished through a sequential process of partial and complete inspection of the finished product which will be described in detail later. Sampling inspection schemes whose aim is to improve the outgoing quality of the finished product is not new in the field of industrial quality control. Various methods are in vogue with varying degrees of statistical validity. The first step towards putting the use of sampling inspection for controlling the outgoing quality on a scientific basis was taken by H. F. Dodge and H. G. Romig of the Bell Telephone system. Dodge and Romig made their inspection plan an adjunct to lot-by-lot acceptance inspection. The basic idea involved in their scheme is briefly described.
