Describe common qualitative scoring scales used in risk assessment.

• A. Scales like A-D letter grades representing risk magnitude.
• B. Scales are random words.
• C. Scales only measure schedule.
• D. Scales like 1-5 or Low/Moderate/High rate probability and impact to yield a risk rating.

Answer: (D)

Qualitative scoring scales in risk assessment use simple, interpretable categories to express both how likely an event is and how severe its consequences would be, then combine those assessments to yield an overall risk rating. Typically you rate probability on a defined scale (for example, 1–5 or categories like Very Low, Low, Medium, High, Very High) and you rate impact on a parallel scale (for example, Insignificant, Minor, Moderate, Major, Catastrophic). By mapping both dimensions, you can translate uncertainty into a clear risk level such as low, moderate, or high, which helps prioritize actions. This approach is helpful because it communicates risk without requiring precise numerical data and supports consistent comparisons across different risks. Other options don’t fit because they either rely on undefined or arbitrary labels (random words), use nonstandard grading like letter grades, or focus on scheduling rather than probability and impact, which are the core dimensions used to rate risk.
