Statistical Process Control II (SPC II)

This seminar builds on the knowledge gained in SPC I. Participants gain an enhanced understanding of uncertainty, sample size selection and probabilities underlying control chart signals. More sophisticated charting tools permitting charting of data collected at multiple locations, non-normal data and trending data is covered as well as other special use charts such as CUSUM and EWMA charts are covered. Computation of non-normal capability is also covered.

Who should attend:
Individuals who are involved in production or service processes including management, engineering and quality and have an interest in using statistical techniques to monitor and control their processes.

Prerequisite:
This seminar builds upon the topics presented in SPC I. A knowledge of basic algebra, statistical process control concepts (SPC I) are strongly recommended.
