Initiative Prioritization Scorer: RICE, Head to Head

Two initiatives, one team, one quarter

Two initiatives reach the planning meeting with one team to staff them. The sponsor of the first has a spreadsheet. The sponsor of the second has a story. The room splits along the usual lines, and the decision goes to whoever argues last.

This calculator puts both through RICE, the scoring method Intercom published for ranking product work: reach, times impact, times confidence, divided by effort ¹. Then it does one thing RICE alone does not. It shows the break-even: how far your confidence, the effort or the reach would have to move before the ranking flips. You leave with two scores and, more useful, the single estimate the decision really depends on.

Before you trust a ranking, find the one estimate that would flip it.

How RICE works

Sean McBride, writing for Intercom in 2018, described a scoring system the team developed after “lots of testing and iteration” to compare project ideas consistently ¹. Four factors, each estimated on a simple scale:

The score is reach × impact × confidence ÷ effort, which McBride describes as “total impact per time worked” ¹. Effort divides because, in his words, “more effort is a bad thing” ¹. In the published example, a project reaching 450 customers a quarter with massive impact, full confidence and two person-months of effort scores 675 ¹.

If you know the prioritization matrix as a value-versus-effort grid, RICE is the same idea as arithmetic: reach, impact and confidence make up the value axis, and effort is the other. The numbers let you rank ten items where a grid only sorts them into four boxes.

Reading the result

Run the defaults. Initiative B scores 800 and Initiative A 675, so B ranks first. Now look at the break-even. B's lead rests on a 50% confidence estimate, and the scores tie if that confidence falls to about 42%. B's reach can shrink from 800 to 675 before A catches up. Those are small margins. The honest conclusion is not “do B.” It is “B wins if our low-confidence estimate is not too optimistic, so spend a week firming it up before committing the team.”

• Break-even far from your estimate: the ranking is robust. Decide and move on.
• Break-even close to your estimate: the ranking is a coin toss on one number. Firm up that number, or pick on other grounds and say so.
• Leader has low confidence: you may be ranking hope over evidence. Ask what it would cost to raise confidence before committing.

Using RICE on strategic initiatives

RICE was built for product projects, and carrying it to strategic initiatives is our adaptation. Two cautions come with it. First, reach must be counted in the same unit for both initiatives; a cost program measured in transactions and a market entry measured in customers cannot be compared on one score. Second, RICE rewards efficiency. It will happily rank a quick, popular improvement above the slow initiative the strategy actually depends on. Settle which initiatives are strategic first, with the four tests, and use the score to order work within that list.

The strongest objection to any scoring model is false precision: multiplying guesses produces a precise-looking guess. McBride's answer, made about the impact scale, is to remember the alternative: “a tangled mess of gut feeling” ¹. He also treats scores as no “hard and fast rule”: a dependency or a table-stakes feature can justify doing a lower score first ¹. With a score in place, he notes, you can see when you are making those trade-offs ¹. The break-even outputs push the same point further. They turn a precise-looking number back into a question about one estimate.

Scoring also helps with the harder half of prioritization, which is stopping. Hollister and Watkins observe that organizations find it surprisingly hard to kill existing initiatives and keep layering new ones on, overloading the levels below the executive team ². A ranked list makes the bottom of the list visible. Use it.

Where to go next

Once an initiative wins its slot, write its charter, including the terms on which it stops. For comparisons that need more criteria than RICE's four, use a weighted trade-off matrix. And if the room still cannot choose after the numbers are in, the problem is usually not the score; our decision-making framework covers what is missing. The score was never the decision. The estimate that flips it is the conversation worth having.

Questions

How is a RICE score calculated?

Multiply reach by impact and by confidence (as a fraction), then divide by effort in person-months. In Intercom's published example, 450 customers a quarter × impact 3 × 100% confidence ÷ 2 person-months gives 675.

Who created the RICE prioritization framework?

Intercom. Sean McBride described it on Intercom's blog in January 2018 as a scoring system the team developed for ranking product roadmap ideas, after testing and iteration.

Is RICE a prioritization matrix?

It is the arithmetic version of the common value-versus-effort grid: reach, impact and confidence form the value side and effort the cost side. A grid sorts items into quadrants; a RICE score ranks them, which helps when many items land in the same quadrant.

Should the highest RICE score always go first?

No. Intercom itself says the scores should not be a hard and fast rule. A lower-scoring item may come first because another depends on it or because customers require it. The score's job is to make that trade-off visible.
