What-if analysis is a technique used to determine how the expected performance is affected by changing the assumptions underlying the prediction. Use What-if analysis to compare different scenarios and their possible outcomes based on fluctuating conditions.
What-if analysis allows project managers to identify event options and impacts, as well as change assumptions. When used properly, project managers can make more informed decisions and more accurately predict the outcome of those decisions.
Sensitivity analysis determines how different values of the independent variable affect a particular dependent variable under certain assumptions. In other words, sensitivity analysis examines how the causes of various uncertainties in a mathematical model contribute to the overall uncertainty of the model.
