Decision Matrix
What Is It?
A decision matrix is a structured tool for comparing multiple alternatives against weighted criteria to make transparent, defensible choices. It forces explicit trade-off analysis by scoring each option on each criterion, making subjective factors visible and comparable.
Quick example:
| Option | Cost (30%) | Speed (25%) | Quality (45%) | Weighted Score |
|---|---|---|---|---|
| Option A | 8 (2.4) | 6 (1.5) | 9 (4.05) | 7.95 ← Winner |
| Option B | 6 (1.8) | 9 (2.25) | 7 (3.15) | 7.20 |
| Option C | 9 (2.7) | 4 (1.0) | 6 (2.7) | 6.40 |
The numbers in parentheses show criterion score × weight. Option A wins despite not being fastest or cheapest because quality matters most (45% weight).
