pm-validation
Use when defining how to know an MVP worked — success metrics, north star, riskiest assumptions, kill criteria, validation plan — or when MVP scope exists but success is undefined. Step 7 of the idea-to-mvp flow.

Step 7 — Metrics & Riskiest Assumptions
"How would you validate?" Define success BEFORE building, and name the assumptions that kill the idea if false.
Prerequisites
Read product/<idea-slug>/00-status.md, 01-intake.md, 03-use-cases.md,
06-mvp-scope.md. Missing → offer to run the producing step, or accept an
equivalent doc. Never reconstruct prior steps from chat memory.
Drafting instructions (dispatch to a subagent when available, else inline)
Draft: (a) ONE north-star metric tied to the #1 use case actually completing — not vanity counts; (b) 2–3 supporting metrics (adoption, retention, quality), each measurable on the MVP as scoped; (c) the 3–5 riskiest assumptions, each with: what must be true, how the MVP tests it, and a numeric kill/pivot threshold; (d) a measurement note — how each metric is captured given the MUST feature set.
PM reaction loop — questions one at a time
- What result after launch would make you KILL this? (If nothing would, the thresholds are too soft — tighten them.)
- Can the MVP as scoped actually measure these — or does a MUST feature need to change?
- Which assumption scares you most? Is the MVP really testing it?
Iterate until approved.
