How it works
Calculate risk priority
The formula multiplies impact, uncertainty, and inverse evidence, then normalises the result to 100.
Predeclare the signal
Choose the observable threshold before running the recommended experiment.

Frequently asked questions
Why multiply the three risk factors?
A factor only becomes urgent when failure matters, uncertainty is high, and evidence is weak. Multiplication makes that combination visible.
Is the recommended experiment definitive?
No. It is the smallest sensible starting test under the entered time and budget constraints.
What counts as evidence?
Observed behaviour and commitments are stronger than opinions. Record where the evidence came from and how representative it is.
