In statistical quality control, the CUSUM (or cumulative sum control chart) is a sequential analysis technique developed by E. S. Page of the University of Cambridge.

May 30, 2025 · A cumulative sum chart (CUSUM) is a type of control chart used to detect the deviation of the individual values or subgroup mean from the adjusted target value.

Aug 3, 2024 · CUSUM stands for Cumulative Sum Control Chart. It is a sequential analysis technique used for monitoring change detection. The idea is to detect shifts in the mean level …

CUSUM charts, while not as intuitive and simple to operate as Shewhart charts, have been shown to be more efficient in detecting small shifts in the mean of a process.

CUSUM (Cumulative Sum) charts improve the ability to detect small shifts (i.e. less than 1.5σ) by charting a statistic that incorporates current and previous data values from the process.

Apr 18, 2023 · A CUSUM (cumulative sum) chart is a type of control chart used to monitor the deviation from a target value. The basic advantage of a CUSUM chart is that it is more …

The Cumulative Sum Control Chart, commonly referred to as CUSUM, is a statistical tool used for monitoring changes in a process mean over time.

This type of control chart monitors the cumulative sum of deviations from the process target. It is designed to detect small shifts in the process average from the target value.

Jun 9, 2025 · CUSUM charts work by accumulating the sum of deviations from a target value. When the cumulative total goes beyond a certain limit, it signals a potential issue with the …

A cumulative sum (CUSUM) chart is a type of control chart used to monitor small shifts in the process mean. It uses the cumulative sum of deviations from a target.
