Cumulative sum, or CUSUM control charts, are well established as being more efficient in detecting small shifts than Shewhart charts. However, the V-mask in CUSUM charts can be more challenging to interpret than in traditional control charts. In this talk, we will present examples that illustrate how the new CUSUM charts can detect small shifts in the mean that are undetectable in Shewhart charts. We will also preview the new CUSUM Control Chart platform options and compare chart efficiencies with average run lengths.
