Explain RICE scoring and its Confidence factor

WHAT IT TESTS: whether you can apply RICE and justify its uncertainty term. ANSWER OUTLINE: RICE score equals Reach times Impact times Confidence divided by Effort, giving a comparable value per unit of work. Confidence is a multiplier, often expressed as percentages like 100, 80, or 50 percent, that discounts Reach and Impact estimates by how much evidence backs them. Determine it objectively by tying each level to evidence: prior experiments and quantitative data earn high confidence, qualitative signals medium, pure speculation low.
