The educational value of using cumulative sum charts

Anaesthesia, 2012
Summary Various workplace‐based assessment tools are available, but none have been shown to improve performance in procedural skills. This study aimed to assess the impact of using one such tool, cumulative sum charts, on procedural skill ability.

Weighted Cumulative Sum Technique

Technometrics, 1989
A class of weighted control schemes that generalizes the basic cumulative sum (CUSUM) technique is introduced. The schemes of the first type, in which the weights represent information concomitant with the data, prove to be especially useful when handling charts corresponding to samples of varying sizes.

Increasing the Sensitivity of Cumulative Sum Charts for Location

Quality and Reliability Engineering International, 2014
The cumulative sum (CUSUM) chart is a very effective control charting procedure used for the quick detection of small‐sized and moderate‐sized changes. It can detect small process shifts missed by the Shewhart‐type control chart, which is sensitive mainly to large shifts.

A novel cumulative EWMA‐sum mean chart

Quality and Reliability Engineering International, 2021
AbstractMemory‐type charts are well‐recognized as an advanced process monitoring tool because of their sensitive nature against small‐to‐moderate shifts that occur in the process parameters. One of those memory‐type charts is a CUmulative SUM (CUSUM) chart.

CUMULATIVE SUM TECHNIQUES FOR SURGEONS: A BRIEF REVIEW

ANZ Journal of Surgery, 2007
There has been increasing awareness of the need for monitoring the quality of health care, particularly in the area of surgery. The Cumulative Summation (Cusum) techniques have emerged as a popular tool for performance monitoring in surgery. They allow one to judge whether a given variation in performance is probably due to chance or greater than could

Introduction to Cumulative Sum Charts

1979
Conventional charting techniques, such as the Shewhart control charts, described in Chapter 5, have the feature that although points are plotted in time, any testing done on them does not take previous values into account. A technique developed in the late 1950s, however, attempts to include information contained in past data points in order to comment

Cumulative Sum Schemes Using Gauging

Technometrics, 1962
Cusum schemes using gauging are developed for controlling the mean and standard deviation of a normal distribution. Tables are provided. The schemes for the mean are generally more sensitive than the corresponding Shewhart ones and only little less sensitive than cusum schemes using measured observations.
