2 Here’s an interesting one: this shoes the outer diameter of a component over time. Notice how in one view, you can quickly see exactly what is happening to the average and SD…without having to deconstruct the averages and standard deviations of a control chart we spend more time actually thinking about the variation causes and not guessing what might be causing the average and/or SD charts to change

3 Here’s one that shows within piece, piece to piece and lot to lot variation. The use of three markers for the within piece location allows us to see that there is a non-random pattern to the within piece variation.
