Advanced Statistical Process Control (SPC)

 

Seminar Content

This two-day seminar is designed to provide participants with an understanding of advanced topics of statistical process control through presentations, illustrations and examples of the analysis of data. Participants learn how to implement SPC within industries that have set up variation, slow and rapid tool wear, and chemical processes where concentration adjustments occur on a daily basis. Emphasis on analysis of the data and effects on the processes using eight types of control charts expands the users' ability to address non-normal, multivariate, and unilateral variables.

The approaches discussed and employed in this course are consistent with the intent and guidelines in the SPC 2nd Edition manual issued by GM, Ford and Chrysler through the AIAG.

Who Should Attend

Individuals who have direct responsibility for defining and developing an Organization's measuring, monitoring and analytical practices using data collection, charts and statistical tools appropriate for its products, processes and business goals and objectives. We will look for suitable statistical tools to identify the same sources of variation in our manufacturing or services and to control that variation.

Pre-Requisites for Course

Participants should possess fundamental knowledge of computational mathematics, a practical understanding of elementary applied statistics, and a basic background in statistical process control. This seminar is designed to be an extension of the first SPC seminar.

Seminar Materials

Each participant will receive a seminar manual and a workbook including all team breakout exercises.
Please bring a calculator.

Seminar Goals

  • To present a hands-on approach to learning the principals and practices of advanced SPC and process analysis
  • Explain optional statistical methods when traditional SPC practices have failed or are inadequate
  • Understand the uses and benefits of advanced control charts and be able to construct and interpret them
