Cusum charts Cumulative sum (Cusum) chart was developed already during the 1950s for change detection. It mainly applies for detecting the change in the mean value. It is somewhat more complicated to use than the Shewhart charts, but more efficient in detecting small shifts in the mean. This is especially true when the changes are
