They entail plotting Q statistics, rather than the traditional mean, range, number of defects, etc. There were some rancorous discussions of their merits during the fall of 1998 in Quality Progress. The first 30-35 pages of the book give a lot of good information about general quality improvement practices.

I have not had much luck locating info on Q-charts. Does anyone know if they have another name ? Or can an online reference be suggested ?
