What is ICE (ICE Scoring)?
ICE scores initiatives on Impact, Confidence, and Ease. Score each dimension from 1 to 10 and multiply them to get the ICE score. It can be useful for a quick backlog comparison when you do not have the Reach data needed for RICE.
Formula
ICE = Impact x Confidence x EaseImpact (1-10): How significantly will this initiative move your key metric if successful? Confidence (1-10): How certain are you about your Impact and Ease estimates? Ease (1-10): How easy is it to implement? (10 = minimal effort, 1 = enormous effort). Example: Impact=7, Confidence=8, Ease=6. ICE = 7 x 8 x 6 = 336. Compare ICE scores across all backlog items to create a ranked priority list.
Benchmarks and interpretation
- ICE scores compare items with each other; there is no universal score or score gap that establishes priority
- Low confidence is a reason to review the evidence and consider further discovery
- Use consistent definitions of Impact, Confidence, and Ease across the items being compared
When to use ICE
- Quick backlog triage when a team needs to decide what to tackle next in the current sprint
- Growth experiment prioritization where Reach is unknown and Ease is the differentiating factor
- Early-stage products with limited usage data where RICE Reach estimates would be speculative
- Quarterly planning sessions where teams need to rank 20+ items in a single workshop
Common mistakes
- Scoring Ease as implementation complexity only, ignoring upstream design, research, and approval effort
- Using ICE for strategic product bets that require deeper analysis - ICE works best for tactical decisions
- Not calibrating the 1-10 scales across the team, leading to different people using the same number to mean different things
Practical tips
- Calibrate by scoring 2-3 completed initiatives first - this anchors the team's mental model of what Impact=7 and Ease=3 look like in practice
- For growth experiments, check what evidence supports Confidence; the standard formula multiplies all three factors without extra weights
- Revisit ICE scores after experiments complete to improve calibration accuracy over time
