The framework
Value per unit of effort.
RICE was described by Intercom’s product team as a simple way to compare ideas that are very different in size.
Score
RICE = (Reach × Impact × Confidence) ÷ Effort
| Input | What it is | Scale |
|---|---|---|
| Reach | How many people or events the change touches in a period | A number, the same period for every item |
| Impact | How much it moves each person it reaches | 3 massive, 2 high, 1 medium, 0.5 low, 0.25 minimal |
| Confidence | How sure you are about reach and impact | 100% high, 80% medium, 50% low |
| Effort | Work needed, across the whole team | Person-months; 0.5 for under a month |
Worked example: an item that reaches 2,000 people, with high impact (2), 80% confidence and 4 person-months of effort, scores 2,000 × 2 × 0.8 ÷ 4 = 800. An item reaching 300 people with medium impact, full confidence and 1 person-month scores 300. The first is worth more per month of work.
Using it well
The ranking starts a conversation.
- Score every item in one sitting with the same people, so the scales mean the same thing throughout.
- A score does not know about dependencies, deadlines, contracts or strategy. Use it to challenge your instincts, not to overrule them.
- If an item’s score surprises you, ask which input you disagree with. That disagreement is usually the useful part.
- Re-score when you learn something. Low confidence is a reason to run a small test first, which raises confidence cheaply.
FAQ
Questions people ask first.
- What is a RICE score?
- A number that ranks ideas by expected value for the effort. RICE stands for Reach, Impact, Confidence and Effort, and the score is Reach × Impact × Confidence ÷ Effort. The framework was described by Intercom’s product team.
- What period should reach cover?
- Any period, as long as every item uses the same one. A common choice is a quarter: how many customers or events the change will touch in that time. Mixing periods makes the scores incomparable.
- How do I estimate confidence honestly?
- Use 100% only when you have data behind reach and impact, 80% when you have some evidence, and 50% when it is mostly a guess. Low confidence should pull a score down: that is its job. If everything is at 100%, the column is telling you nothing.
- Why is effort in person-months?
- It is the amount of work one person does in a month, across everyone involved: design, engineering, testing. Use whole numbers, or 0.5 for something under a month. It only has to be consistent, not exact.
- Is the CSV safe to open in a spreadsheet?
- Yes. Item names that start with =, +, - or @ can be run as formulas by spreadsheet programs, so the CSV puts an apostrophe in front of them and they open as plain text.
