"An important activity at [the Statistical Research Group] was consulting with the military on procedures for inspecting batches of material submitted by suppliers to determine whether they met specification and should be accepted or rejected. Such acceptance inspection, and the closely related problem of inspecting samples of items coming off the production line to control quality, are of long standing, and standard procedures had been developed well before the war. The contributions of SRG were of two kinds. The first was simply to advise the military about relevant procedures and to assist in drafting manuals for various groups to use. The second was to improve the existing procedures. The development of sequential analysis and its application to specific problems was the main contribution of this kind. These activities led to a request that SRG prepare an inspection manual for the Navy.

Because of the obvious peacetime importance of sampling inspection, the work we had done during the war was published after the war in a volume entitled Sampling Inspection: Principles, Procedures, and Tables for Single, Double, and Sequential Sampling in Acceptance Inspection and Quality Control Based on Percent Defective." –excerpt from Two Lucky People, p. 140
