Why This Matters
Not all assumptions in a financial model carry equal risk. Sensitivity analysis separates the assumptions that matter most — those whose variation would significantly change the financial outcome — from those that have minimal impact on the result. This enables management to focus uncertainty management effort on the variables that most affect outcomes, rather than treating all assumptions as equally important. It also provides a quantified basis for assessing how much confidence management should place in a financial projection given the uncertainty in its key inputs.
