Qualitative Scoring
A 3x3 rubric for fast triage
Northwind Trading weighs two threats it cannot yet quantify: a competitor's launch (likely, moderate impact) and a single-supplier parts delay (rare, severe impact). Scored on a 3x3 rubric the competitor move is likelihood High (3) x consequence Medium (2) = 6 -- a High-band risk that gets flagged for a closer look without needing precise data first.
A lighter scale for early triage
Not every risk arrives with numbers attached. Before you can justify a full model, give each risk a quick qualitative score on a 3x3 rubric: a likelihood level of Low, Medium, or High scored 1, 2, or 3, and a consequence level of Low, Medium, or High scored 1, 2, or 3. The qualitative score is the likelihood level times the consequence level, so it runs from 1 to 9. Group those scores into three bands -- Low (1-2), Medium (3-4), and High (6-9) -- and you can triage a whole register in minutes.
Reading the formula
A competitor launch judged likelihood High (3) with a consequence Medium (2) scores 3 x 2 = 6, which lands in the 6-9 High band. A smaller issue -- say likelihood Low (1) and consequence Medium (2) -- scores 1 x 2 = 2, in the Low band. Notice the only possible scores are the products 1, 2, 3, 4, 6, and 9; 5, 7, and 8 never appear, because no two values from 1-3 multiply to them.
The 3x3 rubric trades precision for speed: it cannot tell you the size of a loss, only where a risk sits relative to the others. Use it to sort and flag, then promote the High-band risks for the quantitative work in the next lessons.
- 1. Qualitative score = likelihood level x consequence level = 3 x 2 = 6.
- 2. Score 6 falls in the 6-9 band, so this risk is High.
💡 Hint
- 1. Qualitative score = 2 x 3 = 6.
- 2. Score 6 falls in the 6-9 band, so this risk is High.
Check your understanding
- A 3x3 rubric scores likelihood and consequence each at L/M/H = 1/2/3.
- The qualitative score is likelihood level x consequence level, ranging 1 to 9.
- Scores band as Low (1-2), Medium (3-4), or High (6-9) for quick triage.
