Figure 8.3 Parallelism Plot for Operator and Part
The Parallelism Plots chart shows the average measurements for each part, with each operator overlaid on
the chart. Since the lines are generally parallel and there is no major crossing, you conclude that there is no
interaction between operators and parts.
Tip: Interactions indicate a serious issue that requires further investigation.
In order to draw your main conclusions, examine the EMP Results report.
