Which form identifies each risk event and its characteristics?

The risk assessment is the best choice for identifying each risk event and its characteristics because it is a systematic process that evaluates potential risks associated with a project. It involves defining risk events, analyzing their likelihood and impact, and characterizing each risk in detail. This may include factors like the nature of the risk, its potential consequences, and the context in which it may occur.

A risk profile usually outlines the overall exposure to risk rather than detailing individual risk events, while a risk matrix is a tool used to visualize the severity and likelihood of risks but does not inherently contain descriptive information about each risk event. A risk report typically summarizes various aspects of risk management but may not specify characteristics for each individual risk event in detail. Therefore, the comprehensive nature of the risk assessment process makes it the appropriate choice for effectively identifying and characterizing risk events.
