PMP's project management certification knowledge is based on the application of management theory in projects, combined with PMI's project management ideas and methods. There are qualitative risk analysis and quantitative risk analysis in PMP project management knowledge system.

Perform qualitative risk analysis. The process of implementing qualitative risk analysis determines the priority of risks by evaluating the probability, impact and other characteristics of individual project risks, thus providing a basis for subsequent analysis or action.

Perform quantitative risk analysis. Implement quantitative risk analysis. The process of quantitatively analyzing the comprehensive impact of identified individual project risks and other sources of uncertainty on the overall project objectives.

The main difference between qualitative analysis and quantitative analysis is that qualitative analysis focuses on the nature and characteristics of unit individuals, while quantitative analysis focuses on the number of unit individuals.
