Sensitivity analysis examines each risk variable in isolation to determine which risks have the most potential impact on the project, typically displayed as a tornado diagram that ranks individual risks by the magnitude of their effect on the project cost, schedule, or other objectives.

Using rounds of anonymous surveys to predict which events are most likely to happen describes the Delphi technique, a qualitative expert-elicitation method, not sensitivity analysis which uses mathematical parameter variation.

Using rounds of anonymous surveys to assess probability and impact also describes the Delphi technique rather than sensitivity analysis, which isolates individual variables in a quantitative model rather than collecting expert opinion through surveys.

Determining possible combinations of risk events to predict overall project success or failure describes Monte Carlo simulation, which models the simultaneous effect of multiple risks, not the single-variable isolation approach of sensitivity analysis.
