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?
  • Many medical diagnostics have quick-screening alternatives. For example, there are recent mobile phone apps that screen for HIV, syphilis, and other proteins that indicate disease. If you were designing these apps, would you set them to have a high type I error, or high type II error?
