Reference table
RICE confidence levels and the evidence behind each
The confidence scale from the RICE prioritization framework, with the evidence each level needs. 100% means quantitative data, recent user research or a tested prototype, 80% means some research with open assumptions, and 50% means intuition. Ideas below 50% are moonshots to park until you can validate them. Use it in a scoring session to stop confidence creeping up without proof, and run customer interviews in Koji when you need that proof.
