Quality control charts (QCC) help to visualize the process behaviour in terms of process location and variation. The QCC plots statistics (e.g. number of defects per unit, averages, median values, etc.) over time and compares them to limits (control and sometimes even warning limits) in order to evaluate location and variation. These comparisons lead to a statement about the stability of the process. Top priority is to detect significant changes and to find out how these changes affect the process, If, according to the respective analyses, a process is assessed to be stable, it will be important to maintain or even improve the achieved situation.
