What the score can do
A matrix can support consistent discussion and rough prioritization when definitions are agreed. It does not create a precise probability or financial measure.
What the score misses
- Risk velocity and persistence
- Control confidence and failure modes
- Interdependencies and concentration
- Mandatory legal or safety criteria
- Feasibility and value of treatment
- Uncertainty in the assessment
