The RICE framework is a product-scoring method developed by Intercom that assigns numerical values for reach, impact, confidence, and effort. The reach score is the number of customers who will be impacted; the impact score ranks the anticipated business value; and the confidence score is a qualitative percentage reflecting stakeholder sentiment. These three values are multiplied together and then divided by the effort score, typically calculated in the number of person-months needed. The resulting RICE score allows for a quantitative comparison of products. The ICE method scores products using a similar formula but does not account for reach.
