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.

The Cumulative Sum (CUSUM) algorithm is quite a simple tool used for monitoring change detection in time series data. It is particularly useful in quality control and signal processing.

The CUSUM Chart, short for Cumulative Sum Control Chart, represents an advanced tool within the Six Sigma methodology, particularly under the broad category of Control Charts.

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.

The CUSUM chart plots the cumulative sums (CUSUMs) of the deviations of each sample value from the target value. Because the CUSUM chart is cumulative, even minor drifting in 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.

Apr 24, 2017 · CUSUM is short for "cumulative sum." It is a formula used to determine the gradual change in a series of quantities over time. CUSUM is used in many different professions, …

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.
