is being presented by Dan O'Leary, President, of Ombu Enterprises and airs on Wednesday, December 1st, 2010. For more details or to register, please visit our site at www.fxconferences.com

This audio conference presentation helps attendees understand and implement acceptance sampling, explaining the basis for sampling plans, the binomial distribution, and showing how it helps us understand sampling plan performance using the operating characteristic (OC) curve. Participants gain a solid understanding of the risks involved in sampling by understanding the OC. Our speaker shows how the shape of curve describes risk, and identifies some of the most important points on the curve (AQL and RQL points).

The audio conference provides complete descriptions of three other important curves that help you understand a sampling plan: the average sample number (ASN), average outgoing quality (AOQ), and average total inspected (ATI).

The presentation provides a complete description of Z1.4, showing the process from receiving the lot to selecting the sample size to making the accept/reject decision. The speaker also examines c=0 plans using the curves described above. The OC curve, in these plans, has a different shape that can lead to problems. The presentation looks at some issues with converting from Z1.4 to c=0 plans, especially related to inventory levels and supplier evaluation.
