The classic Pugh Chart was designed for a whiteboard and a conference room. This one distributes scoring to every team member individually, aggregates the results, and shows you exactly where opinions diverge — so the real conversation can finally begin.

The method
The insight isn't in the averages. It's in the disagreements.
The traditional Pugh Chart is a group exercise — criteria on a whiteboard, the team scoring together in real time. It works. But it only captures what the room agrees on by the time the meeting ends.
This platform takes a different approach. Each team member scores independently, on their own device, without seeing anyone else's responses first. When the scores come in, they're aggregated into a single weighted matrix. Now the team can see not just what ranked highest — but where they disagreed, which criteria generated the most spread, and who saw things differently than everyone assumed.
Those disagreements are the most valuable output of the whole exercise. They surface unspoken assumptions, expose unaligned priorities, and flag risks that haven't been named yet. Use it for product concept selection, regulatory pathway decisions, manufacturing partner evaluation, or any decision where multiple informed perspectives need to be considered.
Independent scoring before group discussion doesn't change the decision-making process — it completes it. Every voice is on record before the conversation starts. That's a better foundation for any important call.
Designed to capture every perspective, not just the loudest one
Scoring methods
Numeric Scale
Absolute scoring. Rate each concept from Poor (1) to Excellent (5) per criterion.
Pugh Scale
Relative scoring. Compare each concept against a datum: better (+1), same (0), or worse (−1).
How it works
Add the design options your team is considering. Give each one a name, description, and optional thumbnail image.
Define what matters — trackability, cost, manufacturability, safety — and assign relative weights to each criterion.
Share a session link. Each person scores on their own — privately, without seeing anyone else's responses. No account needed.
See a color-coded matrix ranked by weighted score. Adjust weights live. Drill into any criterion. Export to CSV.
See it in action
A medtech team used Pugh Chart to evaluate three competing catheter tip designs across four weighted criteria. Each team member scored independently — here's what the aggregated matrix revealed.

Rankings
Hybrid Composite is the clear winner with excellent scores across all criteria. Nitinol Braid earns its kink resistance but falls short on manufacturability and pushability. Polymer Flex scores fair across the board — manufacturability is its only relative strength.
Features
Each team member scores privately before seeing anyone else's responses. No anchoring. No groupthink. Just unfiltered individual judgment.
Change criterion weights after scores are collected and watch results recalculate instantly. Perfect for sensitivity analysis.
Choose a 1–5 numeric scale for absolute ratings, or the classic Pugh ±1 scale for relative comparison against a datum concept.
See every individual score alongside the average and standard deviation. Where the team diverges is where the most important conversations live.
Export all raw scores, weighted results, and participant data to CSV. Drop it straight into your design history file.
Only the chart creator needs an account. Everyone else scores via link — no friction, more responses, better data.
