Startup Metrics

Make the decision and definition explicit before interpreting a number.

Workflow

1. Establish the business model, stage, decision, user journey, and natural value interval.
2. Read metric-system.md to define metrics and sources before analysis.
3. When values appear inconsistent or are presented for comparison, keep them both, compare definition, entity, cohort, window, source, and as-of date, classify their relationship, and assign any necessary reconciliation.
4. Read cohorts-experiments.md for retention, segmentation, or tests.
5. Read pmf-evidence.md before making a product-market-fit claim.
6. Return the diagnosis, confidence, limitations, missing instrumentation, proposed action, owner, and review date. If ownership is not established, use owner: unassigned; if a calendar date would be invented, use an evidence-based review trigger such as “after the cohort reaches the defined observation window.”
