Buy vs build
Three options, weighted for cost, speed, and risk
A small team wants a quick weighted-score pass before a longer planning discussion.
Result: Build in-house wins, but not by much
Close-call vendor choice
Two strong options, one weak option
The score gap matters more than the raw label when the top two options are nearly tied.
Result: A weighted matrix highlights whether the lead is decisive or just a nudge
How the weighted matrix works
Each option gets a score from 0 to 10 on each criterion. Those scores are multiplied by the criterion weights, normalized, and added together to create one weighted total per option.
The calculator also compares the winner against the runner-up. That score gap is useful because it shows whether the result is decisive or whether the matrix is really telling you the options are still close.
Decision matrix FAQs
How weighted option scoring works and why the lead size matters as much as the winner itself.
What should the weights add up to?
Any positive total works because the calculator normalizes the weights internally. Many people still prefer using a 100-point scale because it is easier to reason about.
Does the highest score always mean the right answer?
No. The matrix is decision support, not a substitute for judgment. It is best used to make tradeoffs explicit and to surface where a choice only wins because one criterion dominates the weighting.
Why include a confidence label?
Because a narrow win should usually be treated differently from a decisive one. A 0.2-point lead on a 10-point scale is more of a conversation starter than a final verdict.
