What type of methodology would involve structured brainstorming sessions to assign risk values?

The correct choice is qualitative risk analysis because this methodology focuses on assessing risks based on subjective measures and opinions, often through discussions and teamwork. In qualitative risk analysis, structured brainstorming sessions allow team members to identify risks and assign them risk values based on factors such as likelihood and impact. This approach benefits from the diverse perspectives of various stakeholders, which can yield a more comprehensive understanding of potential risks.

Qualitative assessments are typically less about numerical data and more about understanding the context and significance of risks, making them ideal for brainstorming sessions. This process can facilitate a deeper discussion about what the risks entail, how they might affect the organization, and the necessary mitigation strategies.

In contrast, quantitative risk analysis relies on numerical values and statistical methods to evaluate risks, which would not typically involve brainstorming. Collaborative risk assessment might imply a general process of working together but doesn't specifically address the systematic assignment of risk values through structured sessions. Resource allocation is focused on the distribution of resources rather than risk assessment itself.
