Process Quality Control – Cusum Quality Control Charts
After completion the student should be able to set up and use a cusum chart to monitor real changes in level from aim. This would include: 1. setting up and doing the calculations to fill in a cusum table; 2. setting up a quality control graph for plotting cusum data; 3. constructing a cusum template and using it to see if the cusum plot indicates a real shift from aim; 4. resetting the cusum table and graph when a process correction has been made; 5. understanding that the cusum plot more quickly indicates a real shift from aim than regular quality control charts.
Prerequisites: An understanding of average and standard deviation and the ability to read and plot graphs.
