According to the PMBOK® Guide (Project Risk Management), Reserve Analysis is a specific Data Analysis tool and technique used during the process of monitoring and controlling risks.

The purpose of Reserve Analysis in this context is to compare the amount of contingency reserves remaining to the amount of risk remaining at any given time in the project. This ensures that the reserve is adequate to cover the outstanding risks.

Contingency Reserves: These are funds or time set aside to address " known-unknowns " (identified risks).

Management Reserves: These are for " unknown-unknowns " and are generally not part of the cost baseline but are part of the total project budget.

Throughout the project, as risks occur, some contingency reserves are used. Conversely, if risks do not occur or are closed out, the associated reserves may be released. Reserve Analysis helps the project manager determine if the remaining budget is sufficient for the remaining risk profile.

Analysis of Distractors:

A. Plan Risk Management: This process focuses on defining the methodology for risk activities. It does not involve calculating or analyzing specific reserves.

B. Plan Risk Responses: While this process involves determining the amount of contingency reserve needed for specific response strategies, the " Analysis " of those reserves against actual project performance occurs during the monitoring/control phase.

C. Identify Risks: This process is dedicated to discovering which risks might affect the project and documenting their characteristics. It precedes the allocation and analysis of reserves.
