Weighted Decision Matrix
Compare options against weighted criteria. Click a score cell to cycle 1-5, drag the weight sliders, and watch the weighted totals and winner update live. Your matrix saves automatically in this browser.
How the math works: each cell is scored 1-5 (higher is better; for cost-like criteria, give the cheapest option the highest score). Each score is multiplied by the criterion's weight and summed per option. The sensitivity check re-runs the totals with each criterion's weight nudged up and down by 10% of the weight scale to show whether your winner is robust or hanging on a single weight choice.
