The formula
RICE = Reach × Impact × Confidence ÷ Effort
Scales we agreed on
| Factor | Scale |
|---|---|
| Reach | users affected per quarter |
| Impact | 3 massive, 2 high, 1 medium, 0.5 low, 0.25 minimal |
| Confidence | 100%, 80%, 50% |
| Effort | person-months |
How we use it
RICE starts the conversation; it doesn't end it. Anything with confidence under 50% gets a discovery task first.
