RICE vs Weighted Scoring

A fixed four-factor formula or a flexible custom matrix. Pick based on how unique your decision context is and how much setup the team can afford.

Overview

RICE
Fixed Formula

Created by Sean McBride at Intercom, RICE scores each idea on Reach, Impact, Confidence, and Effort. The factors are fixed and the weights are baked in.

Best for backlogs where Reach is a meaningful differentiator and you want a defensible default.

Weighted Scoring
Custom Matrix

A custom matrix where you pick the criteria, assign weights, and score each item against each criterion. Common criteria: revenue, strategic alignment, customer pain, dependencies, risk.

Best for portfolio decisions, cross-functional initiatives, and teams whose strategy doesn't fit a generic framework.

Formula comparison

RICE

RICE = (Reach x Impact x Confidence%) / Effort

Reach is users affected per quarter. Impact is a 0.25 to 3 multiplier. Confidence is 50% to 100%. Effort is in person-months.

Weighted Scoring

Weighted score = sum of (criterion score x criterion weight)

You define the criteria. You set the weights. Most teams use a 1 to 5 or 1 to 10 score per criterion.

When to use each

Choose RICE when
  • Your backlog is a list of comparable features
  • Reach varies a lot between items
  • You want a fast, repeatable score
  • The team is small and you don't have time to design a custom matrix
  • You want a framework most PMs already recognize
Choose Weighted Scoring when
  • Strategy depends on more than reach, impact, confidence, and effort
  • You're comparing initiatives across departments with different success criteria
  • Stakeholders disagree about what matters most. Surfacing weights makes that visible
  • You need to score against company OKRs, regulatory risk, or platform investment
  • You're picking among 3 to 7 big bets, not triaging hundreds of small features

Pros and cons

RICE

Pros

  • Quick to learn. New PMs can apply it inside a week
  • Forces a Reach estimate, which kills opinion-only debates
  • Confidence factor handles uncertainty without dropping the item

Cons

  • Effort in person-months is a lossy estimate. Engineering teams often disagree
  • All ideas use the same criteria. That's a problem when value lives outside Reach
  • Impact is still subjective even with the 0.25 to 3 scale

Weighted Scoring

Pros

  • Reflects your actual strategy, not a generic template
  • Weights themselves become a forcing function for leadership alignment
  • Works for non-feature decisions like vendor selection or hiring priorities

Cons

  • Setup takes real work. Picking criteria and weights is its own debate
  • Easier to game. People shop for criteria that favor their pet project
  • Not directly comparable to scores from another team using different criteria

Frequently asked questions

Can I add my own criteria to RICE?

At that point you're doing weighted scoring. The strength of RICE is that everyone uses the same four factors. Once you start adding criteria, you've built a custom matrix, just one with RICE-shaped roots.

Which is better for an early-stage startup?

RICE if you have any analytics for Reach. ICE if you don't. Weighted scoring is usually overkill for a small backlog. Save it for the moment your roadmap covers multiple bets that compete on different dimensions.

How many criteria should a weighted scoring matrix have?

Three to six is the sweet spot. Two is too coarse. More than six and the weights get small enough that ordering is dominated by noise. If you need a seventh criterion, ask whether it's really a sub-criterion of one you already have.

Do RICE scores compare across teams?

Roughly, yes, if every team is honest about Reach. In practice, teams calibrate Impact differently. Run a calibration session quarterly. Use a shared rubric for what a 1, 2, and 3 on Impact look like.

Can I run RICE first and weighted scoring on the top items?

That's a common pattern. RICE filters a backlog of 50 to 100 items down to a top 10 to 15. Weighted scoring with strategic criteria then chooses among the finalists. You get speed where it matters and rigor where it counts.
