ICE scoring, in depth
ICE optimizes for throughput: a backlog of thirty items can be scored in one sitting, which makes it popular for growth experiments and early-stage backlogs where estimating reach precisely is impossible anyway. The three 1–10 gut ratings are acknowledged approximations.
That looseness is also the caveat — ICE scores drift with mood and scorer. It works best as a first-pass sort that queues deeper discussion for the top of the list, and it works better with several scorers averaging than with one enthusiast rating their own ideas.
Putting it into practice
Score quickly, sort, then sanity-check the top five against actual demand before committing. If a high-ICE idea has zero presence in your feedback inbox or roadmap votes, that absence is information — either an awareness gap or a confidence score that was really hope.
