Learning outcomes

  • Understand the principle of a Shewhart monitoring chart
  • Calculating the limits for this chart
  • Understanding how the limits affect Type I and type II errors
  • Practical issues around implementing control charts
  • Understanding the intention of the CUSUM and EWMA chart
  • Introduction to the terminology of six-sigma, and process capability, with examples

Extended readings

  • In the classes and assignments you've had chances to build fairly easy monitoring charts. Challenge yourself now: build a monitoring chart on the Kappa number data set. Use the first 2000 samples for phase 1, and the remaining data for phase 2.
  • Read the article about "The Toyota Way" to understand partly why Toyota has become one of the more successful car manufacturers.
  • Read this article critically - "Survivor of wrong-way 427 crash that killed husband, daughter, speaks out" (The Hamilton Spectator, 02 April 2015). It has reference to false positives and negatives in two instances: the blood test, and the court's decision. Can you identify both? You do you interpret these in the context of this section of the course material?
