Weighted scoring: rank ideas with criteria your team agrees on (with a worked example)
Run this method in IdeaHone
Creates a space with the entities and scoring criteria of this method, ready for your next session.
Your team has twelve ideas and the budget for one. The impact and effort matrix got you from forty to twelve, but now sales wants the subscription, operations wants the refill station, and nobody can say why one beats the other. Weighted scoring (Nutzwertanalyse in German) gives you a ranked list with reasons: a handful of criteria, weights agreed up front, independent scores, and a total that everyone can trace back to a decision they made together.
When the matrix is not enough
Use weighted scoring when the decision is a real investment, when several stakeholders have to carry it, or when the ideas are hard to compare (a process change against a new product against a partnership). Two scores are not enough for that. Five weighted criteria make the trade-offs explicit and the result explainable to someone who was not in the room.
For a first cut of forty ideas, stay with the matrix. Weighted scoring pays off for 3 to 12 ideas that have survived a first filter.
How to run it
- Choose 3 to 6 criteria. Ask what makes a good idea here, for this decision, not in general. "Customer value", "strategic fit" and "feasibility" are a solid core; add "cost" and "time to first result" if money and speed matter. With ten criteria every idea ends up average.
- Agree the weights before anyone sees the ideas. Weights decided after the ideas are on the table are politics: everyone weights up the criterion their favourite scores well on. Set them blind, write them down, and leave them alone during the session.
- Define the scale with anchors. For each criterion write what a 1 means and what a 5 means. "Feasibility 5: we can build it with the current team this quarter. Feasibility 1: we need a partner we do not have." Without anchors, one person's 3 is another person's 5.
- Score silently and independently. Everyone scores every idea on every criterion alone, before any discussion. Silent scoring stops the first voice from setting the anchor.
- Discuss only the gaps. Where everyone is within one point, take the average and move on. Where two people are two or more points apart, each explains in one sentence, then both score again. Usually one of them knows something the other does not.
- Read the ranking as a conversation starter. Multiply each score by its weight, add up, sort. If the list does not feel right, the criteria or the weights are wrong, not the ideas. Record one sentence of reasoning per idea.
A worked example
A consumer goods team has three ideas left: a refill station in stores, a subscription for consumables, and a packaging redesign. They agreed five criteria and their weights before scoring. Cost and time to first result are inverse criteria: a high score is bad, so they enter the total as 6 minus the score (tools like IdeaHone do that inversion for you).
| Criterion (weight) | Refill station | Subscription | Packaging redesign |
|---|---|---|---|
| Customer value (×3) | 4 (12) | 4 (12) | 2 (6) |
| Strategic fit (×2) | 5 (10) | 4 (8) | 3 (6) |
| Feasibility (×2) | 2 (4) | 4 (8) | 5 (10) |
| Cost, inverse (×1) | 4 (2) | 2 (4) | 3 (3) |
| Time to first result, inverse (×1) | 4 (2) | 2 (4) | 3 (3) |
| Total (max. 45) | 30 | 36 | 28 |
The arithmetic for the subscription: 4 × 3 + 4 × 2 + 4 × 2 + (6 minus 2) × 1 + (6 minus 2) × 1 = 12 + 8 + 8 + 4 + 4 = 36.
What the table tells the team: the refill station has the best strategic fit of the three, but feasibility and cost pull it down. The packaging redesign is easy and cheap, and nobody cares much about it. The subscription wins because it is strong everywhere without being the best anywhere. That sentence is the reasoning you write down.
Score cost and time as the effort until you have learnt something, not until the idea is finished. A four-week pilot of the refill station in two stores costs a fraction of a rollout and would change its score.
How a weighted total ends up misleading
- Too many criteria. With eight or more, every idea scores around 3 and the ranking says nothing. Keep the criteria that would change the decision.
- Weights that encode one person's preference. If the budget owner sets the weights alone, the result is their opinion with a table around it. Set weights as a group, before the ideas.
- Scoring the person, not the idea. The CEO's idea gets a 4 on feasibility because nobody wants to give it a 2. Silent scoring, anchors and ideas without the proposer's name all help.
- Treating the total as the decision. 36 beats 30 means the team's own criteria say so, nothing more. If a 30 feels wrong, say what the number missed and fix the criteria.
- Losing the reasons. Three months later someone asks why the refill station was dropped and nobody remembers. One sentence per idea, next to the score, saves you the same argument twice.
Score and prioritise ideas with your team
IdeaHone scores ideas against your criteria, shows them on a matrix and keeps the reasons, so the decision is clear and traceable.
What is weighted scoring?
Weighted scoring ranks options against several criteria: each criterion gets a weight, each option a score per criterion, and the weighted sum gives the ranking. In German it is called Nutzwertanalyse.
How many criteria should a weighted scoring have?
Three to six. With fewer, a simpler matrix will do; with more, the scores average out until the ranking means nothing.
Is weighted scoring the same as RICE?
No. RICE is a fixed formula with four factors, built for product features. Weighted scoring lets the team choose its own criteria and weights, which takes more preparation and makes the result easier to defend.
