Prioritizes ideas on Impact, Confidence, and Ease — simpler RICE precursor.

ICE Scoring is a lightweight prioritization framework popularized by Sean Ellis in the growth-hacking movement around 2010-2014, scoring candidate ideas or experiments on three dimensions — Impact (how much will this move the needle?), Confidence (how sure are we it will work?), and Ease (how easy is it to implement?) — typically on a 1-10 scale, with the final ICE score computed as the average. Higher scores represent better-bang-for-the-buck candidates. ICE is the conceptual ancestor of Sean McBride's RICE Scoring at Intercom, with RICE substituting Reach for the Ease dimension's inverse and adding effort estimation in person-months. ICE remains common in growth and product teams that want quick relative ranking without RICE's heavier estimation, particularly for experiment portfolio prioritization where Reach is hard to estimate ex ante.

Originators

Sean Ellis (popularization in growth-hacking community) medium

Year / Decade

Early 2010s popularization medium

Primary sources

Ellis, S. & Brown, M. (2017). Hacking Growth, growth-community blog publications throughout the early 2010s medium

Core components

Impact (1-10 scale of expected effect on target metric)
Confidence (1-10 scale of estimation certainty)
Ease (1-10 scale of implementation simplicity)
ICE score = average of three dimensions
Comparative ranking
Experiment-portfolio orientation

Primary use case

Growth experiment prioritization; lightweight product feature ranking; structured comparison of candidates without heavy estimation; foundation for growth-hacking experiment cadence.

Common criticisms

1-10 subjective scoring creates false precision and is highly sensitive to the scorer
team scores vary widely on the same ideas without clear calibration
averaging the three dimensions weights them equally without justification
doesn't address strategic value or option value of learning
dimensions overlap in practice (Confidence often correlates with Ease)
fast iterations can entrench short-term thinking by favoring easy/high-confidence local-maximum work over harder strategic bets
less defensible to skeptical executives than RICE's quantitative inputs.
