Advanced Statistical Process Control (SPC), Second Edition

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.

This seminar is consistent with the DCX, Ford GM manual Statistical Process Control, 2nd edition.

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.

Prerequisite Skills

A basic knowledge of computational mathematics, a practical understanding of elementary applied statistics, and a basic background in statistical process control are important. This seminar is designed to be an extension of the first Statistical Analysis seminar.

Seminar Materials

Each participant will receive a seminar manual, including workbook and all team exercise materials.
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
• Understand the role that SPC plays in the overall Control Strategy for a process and company
