ARQS Decision Matrix · v1.0 · free tool

Choose the road.
Show your reasons.

The crawlerway runs one way to the launch pad, and every turn on it was decided long before. Put your options side by side, weight what matters, knock out anything that misses a must-have, and see which choice wins, by how much, and how easily the answer could change. Free, and nothing leaves this browser.

Weigh it once, properly

A ranking you can defend in the meeting.

Score each option 1–10 on each criterion. Mark criteria where lower is better (cost, risk, effort) and they're inverted automatically. Weights are rescaled to 100%, so you can think in rough importance and still get exact maths.

Go / no-go

Know how solid the answer is.

Sensitivity shows how far each weight must move before the leader changes. A robustness test re-scores the matrix 500 times with every weight varied by up to 25% and reports how often each option still wins.

⚖

Must-haves, not just weights

Set a minimum (or, for costs, a maximum) score on any criterion. Options that miss it are listed separately instead of quietly winning on everything else.

✓

Checks every score

Missing scores, out-of-range numbers and duplicate options are flagged and left out of the ranking until fixed, so a typo can't decide for you.

        What this is, and isn't. A free decision-support tool that runs entirely in your browser: nothing is uploaded and it doesn't look anything up, so the scores are only as good as the evidence behind them. It structures a decision; it isn't financial, legal or procurement advice. Choosing between ARQS-style business ideas? The business-idea template uses the 12-dimension weights from the model ARQS uses to rank projects in its venture directory.
