Likelihood vs. impact: scoring risks honestly

How to use a five-point scale without pretending to know the future.

Published 18 Oct 2026


The risk matrix in this platform uses two five-point scales: likelihood (how plausible is it that this happens within your horizon?) and impact (how badly would it hurt if it did?).

The score

The score is simply likelihood × impact, from 1 to 25. It is a way to compare risks with each other - not a probability.

Tips for honest scoring

  • Score individually first, then discuss differences.
  • When evidence is weak, say so in the evidence field rather than lowering the score.
  • Pay special attention to high-impact risks, even if they seem unlikely.
  • Reassess after every test or major change; the platform keeps the history.
