Step 11 — PMF Signal

Different question from step 7. 07-validation.md asks "did we build the MVP right, and what would kill it before launch?" This step asks "once real people are using it, how do we know we've found product-market fit?"

Prerequisites

Read 00-status.md, 06-mvp-scope.md, 07-validation.md, and 10-customer-discovery.md if its synthesis exists. Missing 07-validation.md → offer to run pm-validation first, or proceed with an explicit Gap: no prior north-star metric note with the PM's consent.

Drafting instructions (dispatch to a subagent when available, else inline)

Draft:

• PMF survey plan — the Sean Ellis question ("how would you feel if you could no longer use <product>?" very disappointed / somewhat disappointed / not disappointed), who to send it to (active users only, minimum usage threshold), and the 40%-very-disappointed pass bar.
• Retention target — a cohort retention curve/number appropriate to the product category, reusing 07's north-star metric as the retained behavior wherever possible instead of inventing a second metric.
• Qualitative signals — organic referrals, inbound demand, usage outpacing marketing spend; drawn from 10's synthesis where it exists.
