ISO/FDIS 7870-6:2024 - Control charts — Part 6: EWMA control charts for the process mean

Introduction: This document specifies the construction and application of an exponentially weighted moving average (EWMA) control chart for monitoring the mean of a process. It outlines methodologies for setting up EWMA charts, including determining appropriate values for smoothing parameters to effectively detect shifts in the process mean over time. Additionally, it provides guidance on interpreting signals from these charts to ensure continuous improvement and quality control.
