Abstract: Abstract This chapter addresses the issue of quality assurance for the incoming materials and the role of purchasing in preventing quality problems to crop up. Communicating specifications unambiguously and completely at the time of placing orders and choosing a vendor who has the requisite process capability to supply quality as per those specifications are the preventive strategies in quality assurance of incoming materials. Design of an optimal inspection policy to get the requisite quality protection against defectives being accepted as good with the minimum inspection cost should be the objective of incoming materials quality assurance program. Acceptance sampling plans, OC curve, AQL, and LTPD are described. In double sampling plans, the decision to accept or reject the lot can be taken after the first sample if the lot quality is very good or very bad, respectively. However, in doubtful cases, a second sample is taken, and based on combined inspection outcomes of the two samples, a decision to either accept or reject the lot is taken.
