Sensitivity Analysis

Definition

Sensitivity analysis is a technique used to determine how different values of an independent variable impact a particular dependent variable under a given set of assumptions. This method helps identify which variables are most influential in determining outcomes, providing insights into potential risks and uncertainties in decision-making processes. By examining how changes in inputs affect outputs, sensitivity analysis becomes essential in evaluating the robustness of models and forecasts, particularly in the contexts of process simulations, ROI calculations for automation projects, and financial modeling.
