How do you explain the purpose of sensitivity analysis in relation to project appraisal indicating the drawbacks with this procedure?

Sensitivity analysis in project appraisal is used to assess how changes in key variables, such as costs or revenues, impact the project's overall viability and outcomes. It helps identify which factors have the most influence on a project's success, allowing decision-makers to evaluate risks and make informed choices. However, the procedure has drawbacks, including its reliance on assumptions that may not hold true, the potential for oversimplifying complex interdependencies among variables, and the difficulty in quantifying certain qualitative factors. Additionally, it may lead to an overemphasis on specific scenariOS while neglecting broader contextual influences.
