Sensitivity Analysis
Change key business assumptions, observe their effect on the result, rank the critical drivers and test how much adverse movement the business case can absorb.
Test which assumptions matter most before relying on a business-case result.
This tool calculates annual operating contribution from volume, price, variable unit cost and fixed cost, then shows one-way sensitivity, driver ranking, break-even values and a compound downside scenario.
Sensitivity Analysis — Step by Step
Eight locked stages move from baseline modelling through one-way sensitivity, driver ranking, break-even analysis, a downside challenge and management review.
Baseline Result, Tornado Analysis and Break-Even Thresholds
Reveal the analysis context to begin.
Interpret sensitivity, break-even and downside exposure.
Build Your Own Sensitivity Scenario
Experiment Mode is isolated from the guided demonstration. Change the baseline assumptions, sensitivity range, target and driver stress without affecting guided progress.
Test sensitivity-analysis judgement.
Sensitivity-analysis cues
One-Way Sensitivity
Change one driver while keeping all other assumptions constant to isolate its effect.
Tornado Ranking
Rank drivers by the size of the output change across the selected test range.
Break-Even Value
Calculate the driver value at which the model result reaches the management target or threshold.
Decision Margin
Compare the current result with the target to understand how much adverse movement the case can absorb.
Compound Downside
Stress several assumptions together to explore a coherent adverse scenario rather than isolated changes only.
Interpretation
High sensitivity means impact is large; it does not mean the adverse movement is more likely.
Use one-way sensitivity, break-even analysis and compound downside scenarios together to understand both individual driver impact and combined adverse exposure.
