Control charts have been widely used in industries to monitor process quality. We usually use two control charts to monitor the process. One chart is used for monitoring process mean and another for monitoring process variability, when dealing with variables data.

A problem with the conventional Shewhart charts is that the decisions are usually based on single observations. Such decision implies a high probability of false alarms. Also, small shifts in the process characteristics, which are of increasing importance from the point of view of efforts for continuous quality improvement, cannot be detected easily ...

In the analysis of both variables and attributes as described in the previous chapters, the readings were plotted in time sequence and out-of-control situations determined by using the four rules for special causes. Two of these rules (the rule of seven and the middle third rule) did take into account the position of points previous to the one being ...
