TEN-POINT SELF-REVIEW — not a graded or accredited assessment
Score each area 0 (missing/wrong), 1 (partly usable) or 2 (clear and reproducible).
1. Decision and neutrality: audience, alternatives, question; no assumed positive effect.
2. Scope and provenance: ticket grain, exact cohorts/cutoff, maturity, source and exclusions.
3. Metric correctness: denominators, coverage, units, weights and missing/zero behavior.
4. Method and validation: ordered steps, reconciliation and data requests with actions.
5. Interpretation and handover: alternative explanations, no causal overclaim, clear deliverables/review dependencies.
Suggested learning target: >=8/10 with no zero in scope or metric correctness and no unsupported causal claim. Revise otherwise. This is a learning guide, not company rollout approval.
Independent contribution: explain the fixed-weight comparison and identify one new justified data request. Label guided material and fictional source honestly in a portfolio.
