Vendor Comparison Matrix

Q: How do I know the Vendor Comparison Matrix output is good?

The skill verifies itself against its own quality checks: Criteria and weights predate all demos, with owners named; Must-haves gate before any scoring charm applies; Every score carries its evidence flag; finalists' key criteria reached ✅; TCO includes both switching costs.

🔵 Stable🕐 updated 2026-07-19 🔷 SkillSpec L3 pm-cowork

Compare vendors on a matrix that decides instead of decorates — the criteria weighted before the demos (so the shiny demo can't rewrite them), the evidence-based scoring with the marketing-vs-verified flags, the total-cost row that includes switching, and the reference-check questions that get honest answers. Use when asked compare these vendors/tools, build the selection matrix, the demo wowed us now what, or make this procurement decision defensible. Produces the weighted matrix, the scoring evidence rules, the TCO row, and the reference-call script.

What to give it

▸The requirements, from the users — what the actual users need done (not the feature wishlist — the jobs); must-haves separated from nice-to-haves *before* any vendor contact ([proposal-skeleton](../proposal-skeleton/SKILL.md) honesty applied to procurement)

▸The vendor set — the candidates, including the incumbent/do-nothing option scored on the same matrix

▸The weights' owners — who says integration matters more than UI? Weights are decisions with owners, set in a room, pre-demo

▸The switching context — what leaving the current tool costs (data migration, retraining, the [vendor-breakup-email](../vendor-breakup-email/SKILL.md) terms) — TCO's most-forgotten row

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓Criteria and weights predate all demos, with owners named

✓Must-haves gate before any scoring charm applies

✓Every score carries its evidence flag; finalists' key criteria reached ✅

✓TCO includes both switching costs

✓At least one reference question pierced the curation

⚠️ What it refuses to do

Do not build the matrix after the favorite emerges — that's a justification wearing a grid

Do not let demos add criteria silently — discoveries route through the weight-owners

Do not score marketing claims as facts — the flags exist because 📢 and ✅ are different knowledge

Do not compare license prices as costs — TCO or the cheap option costs the most

Do not skip the incumbent row — every selection is versus something, and do-nothing has a score
