Identify the inputs that matter most with clear, automated reports—right inside Excel.
“I built these add-ins after 20 years
analyzing and modeling business
decisions with Microsoft Excel.
My goal was to make them easy to
learn and use.”
Sensitivity analysis is a vital part of quantitative decision analysis. TruSens makes it easy by automating five major report types — tornado charts, spider charts, strategy region graphs, two-variable 3D charts, and two-variable strategy tables.
TruSens works seamlessly with Microsoft Excel. It can be used with or without SolutionTree to automate your sensitivity analysis.
Analyze the relative sensitivity of multiple variables with professional tornado and spider charts. Quickly identify which variables have the greatest impact on your results.
Visualize strategic regions, two-variable sensitivities, and strategy reports to understand how changing assumptions affect the best decision.
Join thousands of professionals who use TruSens to make smarter decisions every day.

This is a favorite among decision analysts, but one of the most difficult to implement. Horizontal bars are used to show the relative impact of each independent variable and, because they're ranked from top to bottom, the chart resembles a tornado.
Spider charts also shows the relative sensitivities of multiple variables from a single dependent variable. In this case, however, the values on both axes of the chart are depicted as percentage values using line graphs, resembling the legs of a spider.
This chart is used to visualize the impact that a single independent variable has on one or more dependent variables. The dependent variables are typically mutually exclusive options. Usually, multiple dependent variables are graphed relative to each other, revealing the strategic regions for each option.
Surface charts and the 3D-column charts are used with two-variable sensitivities, i.e. two independent variables and a single dependent variable. The only difference is the chart type used. Sometimes a surface chart will let you visualize the data better, and sometimes a 3D column will. Use both to get a different look on the same output.
This report is unique among the TruSens reports in that it is not a chart. It not only measures the sensitivity of multiple dependent variables as two independent variables are adjusted, it tells you what the best option is under any of the scenarios. Usually, the dependent variables are mutually exclusive options and you are trying to determine which option is best assuming different combinations of the two independent variables.
The PRO version includes a full-featured version of TruSens, all under a single tab in the Excel Ribbon.
