What is a qualitative risk assessment and when is it appropriate?

• A. A risk assessment using descriptive scales (low/medium/high) without numeric probabilities; appropriate when data is scarce or rapid assessment is needed.
• B. A risk assessment that uses precise numerical probabilities and expected losses.
• C. A risk assessment that only considers financial risk.
• D. A risk assessment based on historical incidents without any rating.

Answer: (A)

Qualitative risk assessment describes risk levels with descriptive terms (low, medium, high) rather than precise numeric probabilities or monetary losses. This approach is ideal when data is scarce, uncertainty is high, or you need a quick, high-level view to prioritize actions. It allows teams to rank risks and decide where to focus controls without waiting for detailed statistics, making it practical for early-stage projects, rapid safety reviews, or situations with limited data. The other approaches pull in different methods: using precise numerical probabilities and expected losses is a quantitative risk assessment, which requires solid data and more time. Narrowing the scope to only financial risk ignores the broader, often safety-related impacts such as injuries or environmental harm. Building a risk picture from historical incidents without any rating lacks a structured scale to compare and prioritize risks, which is a key feature of qualitative assessments even when the scale is descriptive.
