Five numbered steps to build a weighted decision matrix. Criteria, weights, and scoring rules included.

Five example criteria with weights (User Impact 30%, Business Value 25%, and more) plus live weighted-score formulas in the sheet. Opens in Excel, Google Sheets, and Numbers with the score formulas already wired up. No email required.
Weighted scoring compares a fixed set of options against the same criteria. Start by writing down exactly what you are deciding and which options are in the running.
Formula
Decision matrix = one decision, 3-10 named options, scored against shared criteriaPro tip: If the decision is already made and you're building the matrix to justify it, stop. A gamed matrix costs you credibility the next time you need the team to trust a ranking.
Criteria are the dimensions you will judge every option on. Pick the ones that matter for this specific decision, and keep the list short.
Formula
Criteria set = 5-7 independent, defined dimensions per decisionPro tip: More than 8 criteria is where analysis paralysis sets in. People hold about 7 items in working memory (Miller's Law), and a 12-criterion model takes twice as long to score without changing the answer.
Weights encode what matters most. This is the step that makes the model yours, and the step teams most often dodge.
Formula
Weights = forced ranking of criteria, each differing by 5+ points, summing to exactly 100%Pro tip: Equal weights because deciding is hard is the classic failure. A 20-20-20-20-20 split is just an unweighted average, and the model stops reflecting what actually matters to you.
Work through the matrix one criterion at a time, scoring all options on that criterion before moving to the next. This keeps the scale consistent.
Formula
Score = 1-10 per criterion, with cost and risk criteria scored invertedPro tip: Forgetting to invert cost and risk is the most common spreadsheet error in weighted scoring. If your riskiest option just topped the ranking, check the direction of those columns first.
Each option's weighted score is the sum of its criterion scores multiplied by the criterion weights. Rank descending, then interrogate the result before acting on it.
Formula
Weighted Score = sum of (criterion score x criterion weight) across all criteriaPro tip: The matrix informs the decision; it doesn't make it. If leadership overrides the ranking for strategic reasons, document the override instead of quietly re-scoring until the numbers agree.
Skip the spreadsheet. The free weighted scoring calculator validates that weights sum to 100%, recalculates as you adjust, and runs sensitivity analysis on close calls.

More than eight and scoring sessions stall: people hold roughly seven items in working memory, and marginal criteria add debate without changing the ranking. Teams that trim bloated 10-12 criterion models down to 5-7 reach the same decisions faster.
Force rank the criteria first, then assign percentages that follow the ranking, differ by at least 5 points each, and sum to exactly 100%. Keep any single criterion at or below 50% so one factor cannot dominate. Document why each weight is what it is. Weights should also be revisited each quarter, because they encode strategy and strategy shifts.
RICE is a fixed formula: Reach, Impact, Confidence, and Effort, always those four, designed for feature backlogs with user data. Weighted scoring lets you define the criteria and their importance yourself, which fits decisions RICE cannot express: vendor selection, strategic bets, tech debt, or anything where compliance, risk, or stakeholder priorities matter as much as user impact. Use RICE for standard feature prioritization and weighted scoring when the decision has dimensions RICE does not capture.
Settle weights before anyone scores, not after, because post-hoc weight changes look like ranking manipulation. Have each stakeholder force rank the criteria independently, compare the rankings, and negotiate the gaps in the open. The argument about weights IS the alignment work: a sales lead pushing for 40% on revenue and an engineer pushing for 30% on feasibility are surfacing a real strategic disagreement the matrix just made visible. If consensus fails, the decision owner sets the weights and records the rationale.
Skip it for routine backlog prioritization (RICE or ICE rank 20 features in a fraction of the setup time), for quick low-stakes calls where the overhead outweighs the decision, and for decisions that are already made, where the matrix would only exist to justify the answer. It earns its setup cost on complex, high-stakes choices: multi-stakeholder roadmap calls, vendor selection, or strategic initiatives with competing dimensions.
