Questions

Frequently asked questions

How is a RICE score calculated?

Multiply Reach, Impact and Confidence, then divide by Effort. Reach is how many people the idea touches in a set period. Impact uses a fixed scale: 3 massive, 2 high, 1 medium, 0.5 low, 0.25 minimal. Confidence is 100%, 80% or 50%. Effort is person-months. A higher score means more value for the work involved.

RICE or ICE: which should I use?

ICE is quicker. You score three things from 1 to 10 and multiply them, so it suits a fast first pass through a long list. RICE adds a real reach number and divides by effort, so it takes longer but separates a small fix for many people from a big build for a few. Use ICE to cut a list down, then RICE on what is left.

What counts as reach and effort?

Reach is the number of people or events the idea affects in one period, such as sign-ups per quarter. Pull it from analytics where you can, and use the same period for every idea. Effort is the total person-months from design, development and testing together. Use the same unit throughout, and round up if you are unsure.

Are the scores objective?

No. Impact and confidence are judgement calls, and a different team would score the same idea differently. The numbers are only useful for comparing ideas within one list, scored by the same people on the same day. Treat the ranking as a starting point for a conversation, not a decision.

What do I do with the ranked list?
Look at the top few and ask if the ranking feels wrong. If it does, one of the scores probably is. Then turn the winners into work you can plan with the user story generator.
