What is ICE scoring?
ICE is a quick way to rank ideas, popularized by Sean Ellis for choosing growth experiments and now widely used for features too. Each idea gets three ratings from 1 to 10:
| Impact | How much will this move the thing you care about (retention, sign-ups, revenue) if it works? |
|---|---|
| Confidence | How sure are you that it will have that impact? Evidence, like customers asking for it, earns a high number; a hunch earns a low one. |
| Ease | How easy is it to do? 10 is an afternoon, 1 is months of work. |
ICE score = Impact × Confidence × Ease
Some teams average the three numbers instead of multiplying. The order comes out similar; multiplying spreads the scores further apart, which makes the top of the list easier to see.
ICE or RICE?
ICE is faster: three gut-feel ratings, no counting. That makes it good for a long list of small ideas, or experiments you’ll run and measure anyway.
RICE adds Reach (how many people are affected) and measures effort in real time units, so it’s better when ideas differ a lot in how many users they touch, or when you need to explain a decision to others.
Both are only as good as the ratings. The most common mistake with ICE is rating everything 6 to 8, so be strict about using the whole scale.
Other prioritization methods
Raise Confidence with evidence
Confidence is where customer feedback earns its keep. An idea that dozens of customers have asked for deserves a higher number than one that came up in a meeting.
UserNote gives you a feedback board where customers post ideas and vote without creating an account, so you can see how many people want each one before you rate it.
