Sensitivity analysis attempts to assess the impact of a change in the input data or parameters on the proposed solution.
Sensitivity allows flexibility and adaptation to changing conditions and to the requirements of different decision-making situations.
Sensitivity analysis tests relationships such as the following:
The impact of changes in external (uncontrollable) variables and parameters on the outcome variables(s)
The impact of changes in decision variables on the outcome variable(s).
The effect of uncertainty in estimating external variables
The effects of different dependent interactions among variables
The robustness of decisions under changing conditions
