Use peer percentiles to anchor success thresholds that reflect your stage and margins. Document seasonality assumptions, minimum detectable effects, and acceptable regression on secondary metrics. Pre-register guardrails before launch to curb p-hacking, and publish postmortems that connect results to next steps, strengthening shared judgment across product, marketing, and finance teams.

Monitor sequentially with conservative spending rules, and compare posterior outcomes to percentile bands, so go or no-go calls respect uncertainty while still empowering timely decisions that conserve momentum and resources.

Numbers inform, stories persuade. Summarize each experiment with the problem, insight, intervention, and outcome, then connect changes to the North Star and key drivers. A fintech team learned that shifting KYC to post-value raised day-seven retention.
