According to the PMBOK® Guide, the process of prioritizing individual project risks for further analysis or action by assessing their probability of occurrence and impact, as well as other characteristics, is the definition of Perform Qualitative Risk Analysis.

Core Objective: The primary goal is to reduce the level of uncertainty and focus on high-priority risks. Since it is impossible to give every identified risk the same amount of attention, this process allows the Project Manager to categorize risks as high, medium, or low.

The Probability and Impact Matrix: This is the key tool used in this process. It combines the probability of a risk occurring with the impact it would have on project objectives (such as schedule, cost, or quality) to assign a risk score.

Subjective Nature: Unlike quantitative analysis, qualitative analysis is often performed quickly and cost-effectively. It relies on the perceptions of the project team and stakeholders to gauge the severity of risks.

Comparison with Other Options:

Monitor and Control Risks (A): This process involves tracking identified risks, monitoring residual risks, and identifying new risks. It does not perform the initial prioritization.

Plan Risk Management (B): This is the planning process that defines how risk management activities will be structured and performed; it provides the templates and scales for the matrix but does not assess the specific risks.

Perform Quantitative Risk Analysis (D): This process numerically analyzes the combined effect of identified individual project risks on overall project objectives. It usually follows qualitative analysis and provides a more rigorous, data-driven assessment of project-level risk.
