Decision Matrix Generator — illustrative example

INPUT
Decision scores use 1–5, higher better. A: speed 5, cost 2. B: speed 3, cost 5. Compare equal weights with speed 0.8 and cost 0.2.

RESULT
Equal weights:
A = 5 × 0.5 + 2 × 0.5 = 3.5
B = 3 × 0.5 + 5 × 0.5 = 4.0
B ranks first.

Speed-heavy weights:
A = 5 × 0.8 + 2 × 0.2 = 4.4
B = 3 × 0.8 + 5 × 0.2 = 3.4
A ranks first.
The preferred option depends on the decision owner's priorities; the matrix does not choose those priorities.

REVIEW
A decision matrix clarifies preferences but cannot choose the right weights for you. Test whether small weight changes alter the preferred option.
