All Quality Discussion Group (QDG) events are free to attend and open to anyone interested in participating in the discussion.
For any time sequence data (e.g. product quality at different time), run chart (plotting product quality vs. time) is a simple and yet effective way to analyze the data. When the data are the deviations from the target/ set point, then plotting the cumulative sum of the deviations vs. time is a very useful addition to the run chart. This type of chart is known as CuSum plot in Statistics. The aim of this presentation is to introduce the CuSum plot.
