The sensitivity tool reveals the inputs with the biggest impact on your optimized Plan.
The tool works by changing selected inputs in your Plan one at a time to see how much those changes affect the expected VNM utility of your optimized Plan.
Sensitivity details are automatically displayed whenever you run Plan optimization.
You can choose to see sensitivity details for:
You can choose different +/- percentages to see how sensitive your optimized Plan is to inputs being increased and decreased by those percentages.
If you are using variables with best and worst case values, you can also see how sensitive your optimized Plan is to those variables being changed between their best and worst case values.
Sensitivity details are displayed in the form of a horizontal bar chart.
Each horizontal bar represents an input that has been changed by the sensitivity tool, according to your selected sensitivity options.
The horizontal bars are aligned around a central vertical line which represents the base expected VNM utility for you optimized Plan.
As the sensitivity tool changes each input, the horizontal bars will extend out from the central line to show how much those changes impact the expected VNM utility of your optimized Plan.
If changing an input also changes the optimal decision for your Plan, a red icon appears next to that input's horizontal bar as follows:
There are 2 ways to use sensitivity details to identify key inputs for your Plan:
In both cases, you should consider giving these inputs special attention to ensure they are as accurate as possible.
