Abstract: The
Paynter Chart is a tool that goes beyond a Pareto.
A Pareto focuses on problems that offer the
greatest potential for improvement by showing
their relative frequency or size. A Paynter
Chart goes beyond the Pareto by sub-grouping
the Pareto bars. The subgroups could be days,
hours, etc.

The Paynter Chart is based on the Pareto principle,
which focuses on the areas of priority and quickly
puts them in a simple graphical form by subgroups.
It helps your team focus their efforts where
they can have greatest impact. It allows you
to determine the composition of each bar for
troubleshooting or spotting trends.
Figure 1 below illustrates a Pareto Chart,
while Figures 2 and 3 show examples of the Paynter
Chart.

This Paynter was run by restricting the number
of groups to 5 and the number of subgroups to
4. In this case it took the last 4 subgroups
to plot.
Notice, also that the number at the top of
the group is the total defects for that group,
but is not the sum of the subgroups shown.

This chart illustrates 5 defect codes with
4 subgroups where the subgroups plotted are
those with the largest number of defects for
the defect codes plotted.
