Sensitivity analysis is a method for limiting and hedging uncertain variables and values (critical value method). Based on the respective method, e.g. for assessing an investment, such as cost comparison, profitability or net present value method, the S. is intended to answer the question of how far a variable can deviate from its original value without the result exceeding or falling short of a specified value, or to what extent a result changes if one or more input variables deviate from their original value.
The S. is also used for weighting utility value analyses.
