Acceptance sampling plans are important tools for manufacturers. Effectively used they can help reduce costs while assuring quality and controlling risks. Unfortunately, this rich field of techniques is not as prominent as it once had been. As a result, quality practitioners don't always appreciate the wide range of available options or understand how to choose among alternate statistical sampling plans.

Because there are no published standards or guides to help select the right technique for each application, this workshop invaluable. For example, a sampling plan to make an acceptance decision on an incoming lot is not the right plan to sample records in a quality audit. Even incoming inspection has many viable options - variables sampling plans can significantly reduce inspection cost compared to common attributes sampling plans.

This workshop balances understanding the statistical concepts of sampling and creating practical applications. The workshop uses a large number of exercises to help participants understand the theories, master the techniques, and participate in practical exercises.

Any company that uses sampling plans can benefit from this workshop. The workshop uses examples from medical device manufacturing. However, the methods, tools, and techniques are not industry specific.


Why should you attend:

Nearly all companies use sampling plans as part of quality control and quality assurance. However, some methods are better suited to certain applications. Understanding the available methods can help make better choices to optimize cost and conformance.


Workshop Objectives:

Participants will learn the statistical basis for acceptance sampling plans and the tools and methods to describe them, particularly the Operating Characteristic curve. This forms the basis for selecting sampling plans and understanding the associated risk. In particular, regulators, such as FDA Investigators, expect companies to use this information to help implement valid statistical techniques. However, cost is a consideration as well. Participants will learn how to calculate sampling costs and use the information to help choose efficient plans that control the risk.

Participants receive a set of Excel spreadsheets that help explain and implement the sampling plans.
