ICE Score is a simple prioritization framework: rate each feature idea on Impact (how much will it move the needle?), Confidence (how sure are we?), and Ease (how easy to build?), each on a scale of 1-10. Multiply them: ICE = Impact × Confidence × Ease. Highest score wins. It forces you to think beyond "this sounds cool" and consider effort and certainty. Quick to use, less rigorous than RICE.
Use ICE scoring when you have too many feature ideas and need to prioritize, when debating roadmap with your team, or when you want a lightweight framework (no need to estimate users reached like RICE). Best for small teams moving fast. Update scores as you learn—Confidence changes after user interviews, Ease changes after technical spikes.
