The next new chart is for impact analysis.
Therefore we call it the Impact chart.
It tells you which
What If variables have the greatest impact upon a Goal variable and how much impact.
With impact analysis you are asking “If I move these What If variables by ‘x%’
what is the impact is on my Goal variable?”
Go ahead and drag the Impact chart onto the stage. Drag the variable Total Westlake profit to the top of the empty chart where it says “Drag goal variable here”. Now drag all the What If variables from the Sales Volume node onto the empty chart. Across the bottom is a slider bar with time periods. Move it to 2009. Vertically on the right is another slider bar that controls percent change. Move it to zero and you see there is nothing in the chart. That means if you don’t move any What If variables there is no impact upon the goal variables. Now move the slider up by 10 percent. You can also type your desired impact value in the text field just below the percent change slider.
