About the Course

This course provides detailed methodology on how to set up Statistical Control Charts relevant to test method performance monitoring over time as per ASTM D6299. The course begins with an overview of the importance of data trustworthiness as a key business driver, followed by understanding common cause variation between test results using Statistical Thinking. Precision fundamentals, Industry standard test method precision performance metrics such as repeatability, reproducibility, site precision, and associated business applications will be presented in detail as the first topic, to serve as a foundation upon which the Statistical Control Charts methodology are based on. Bias fundamentals, along with use of Statistical Control Charts and other statistical techniques for assessing and monitoring laboratory bias over time versus industry, will be covered in detail, followed by an overview of relative bias between test methods as the final topic. The course will be conducted in a virtual setting, with web-based demonstrations for the set up and maintenance of statistical control charts, using example data from a variety of quality control testing results. Special techniques dealing with quality control material transition, accrual of control chart statistics over time, non-normal data, and inadequate measurement resolution will be covered.

Motivation

Since trustworthy measurement data is a fundamental enabler to all aspects of business improvement, having a fundamental understanding of testing precision, bias (absolute and relative), data quality, how to design and execute control chart work processes to ensure data quality, and the implicit uncertainties associated with measurement data can significantly enhance business process improvement initiatives. Understanding test method performance behavior from control charts can lead to correct decisions as to when to adjust and when not to adjust test methods or process control strategies. Use of control charts to monitor testing performance and apply pre-emptive just-in-time failure-prevention actions can improve laboratory and field operations efficiency, reduce waste, and assure the test data produced are fit-for-use and defensible. Understanding of test method precision and bias enables release of product with confidence at optimal production cost.
