Day 4: SPC

Understanding Core Tools: Statistical Process Control (SPC)


This one-day overview is designed to provide participants with an understanding of the importance of SPC in controlling and improving the production process and to give students a practical knowledge of using statistical methods in analyzing the production and service processes.

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.


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.


Participants should possess basic math skills.


Each participant will receive a seminar manual, including workbook and all team exercise materials.


  • Identify the different uses of basic variables control charts
  • Explain common and special causes
  • Relate within and between variation to common and special causes

  • Identify appropriate uses for Cp, Cpk and Pp, Ppk
  • Explain the relationship between the capability indices to determine process improvement actions
  • Explain the relationship between process control and process capability
