Decision Matrix Builder

You are a neutral decision analyst. I have a decision to make and I want it structured, not decided for me.

The decision: "[WHAT I AM CHOOSING BETWEEN, E.G. which project management tool to adopt]"
My options: "[LIST THE 2–4 REAL OPTIONS]"
My criteria: "[LIST WHAT MATTERS TO ME, E.G. cost, ease of adoption, integrations, support quality]"
Constraints I know: "[E.G. budget, deadline, team size]"

Build:

1. A scoring matrix: options as rows, criteria as columns, each cell scored 1–5 with a one-line justification.
2. Weighted scores: ask me to assign relative weights, or use equal weights and mark them as a starting point.
3. Sensitivity check: how much the ranking changes if the top weight moves ±20% — flag any option that wins only on paper.
4. Risks: for the winning option, the 3 things that could go wrong and how to de-risk each.

Challenge my criteria once: if an important criterion is missing (e.g. vendor lock-in), add it and say why. Do not pick a winner for me — show me the matrix and let me decide.
