Abstract: The purpose of this paper is to introduce the regression control chart for two related variables and to furnish rules for a plan of action. Cases are presented to show the effectiveness of the regression control chart. A Regression control chart for two related variables integrates linear regression and Shewhart quality control chart theory and methods in a coherent way. The regression control chart combines two robust methods as the basis of analysis: the linear regression model and the Shewhart control chart theory. Other researchers are encouraged to investigate related variables using a regression control chart as there is a lack of published work in this area.

Keywords: regression control chart; Shewhart; variation; process improvement.
