This document covers EWMA control charts, originally proposed by Roberts (1959)[16], as a statistical process control technique to detect small shifts in the process mean. It makes possible the faster detection of small to moderate shifts in the process mean. In this chart, the process mean is evaluated in terms of exponentially weighted moving average of all previous observations or averages.
The EWMA control chart’s application is worthwhile in particular when
it involves safety risks.
NOTE EWMA control charts are applicable for both variables and attributes data. The given examples illustrate both types (see 5.5, AnnexA, AnnexB and AnnexC).
