Step 7: Sensitivity analysis
In impact assessments, uncertainties can be introduced in many ways. In order to test the influence on the end-result of changes to important effects or those with non-robust underlying assumptions, a sensitivity analysis can be carried out for those effects.
1. Testing the assumptions
Sensitivity analysis is used to test the influence of (suspected) non-robust assumptions on the final results.
It involves re-running the assessment using altered values for those items that are considered to be prone to uncertainty.
