# Decision Matrix ## Overview A weighted decision matrix (a.k.a. weighted scoring model, Pugh matrix, or trade study) turns a fuzzy "which should I pick?" question into a transparent, defensible number. You list the **options** (the things you choose between), the **criteria** (what matters), assign each criterion a **weight** (how much it matters), score every option on every criterion, and compute a weighted total. The highest total is the recommended choice. Keywords: decision making, weighted scoring, trade-off analysis, multi-criteria decision analysis (MCDA), Pugh matrix, vendor selection, job offer comparison, prioritization. Use this skill whenever someone must choose among 2+ discrete alternatives and wants the reasoning to be explicit rather than a gut feel. Do **not** force a matrix on a binary yes/no decision or a problem with a single dominant constraint — say so instead. ## Workflow Follow these steps in order. Confirm with the user at steps 1–4 before computing. 1. **Frame the decision.** State the single question being answered (e.g. "Which CRM should we adopt?"). One decision per matrix. If the user has bundled several decisions, split them. 2. **List the options.** Gather 2–7 concrete alternatives. Fewer than 2 is not a decision; more than ~7 becomes noisy — shortlist first. Always consider adding a baseline "do nothing / status quo" option when relevant. 3. **Elicit the criteria.** Ask what factors matter. Aim for 4–8 criteria. Each mus...
