Perform Quantitative Risk Analysis focuses on:

Compiling a list of known risks and preparing responses describes the Identify Risks and Plan Risk Responses processes, not Quantitative Risk Analysis.

Assessing probability of occurrence and impact for each risk describes Perform Qualitative Risk Analysis, which uses subjective scales rather than numerical modeling.

Evaluating contingency and management reserves is an output informed by Quantitative Risk Analysis but is not the definition of the process itself.

Quantitative Risk Analysis uses numerical techniques such as Monte Carlo simulation and sensitivity analysis to quantify the probable effect of individual risks on overall project schedule and cost objectives. It produces numerical probability distributions for project outcomes, supporting data-driven contingency decisions.
