What should you vary in a robust sensitivity analysis?

• A. Price and volume only, keeping costs fixed.
• B. Key drivers such as volume, price, costs within plausible ranges; present breakeven points and ranges of outcomes.
• C. Only macroeconomic indicators.
• D. Only one driver to simplify.

Answer: (B)

Varying the key drivers within plausible ranges is how a robust sensitivity analysis reveals what really matters. You should test major levers such as volume, price, and costs across realistic bounds and show how outcomes like profit or cash flow move, including where you break even and the range of possible results. This approach captures uncertainty and how different factors interact, giving a clear sense of risk and the margin of safety. Narrower approaches—fixing costs, or looking only at price and volume, or focusing on a single driver—miss how cost dynamics and other influences shape outcomes and fail to show the full range of possible results.
