Experiment Registry: Stop Tests From Colliding

Running lots of tiny tests is how small teams learn fast — until overlapping promos, mixed messages, and accidental rollouts erase lift and waste budget. This episode teaches a lightweight, governance-first “Experiment Registry” you can pilot in 21 days to reduce conflicting tests by ~70% and free up 3–5 hours/week for owners. We open with a founder story: three simultaneous promos cancelled a 12% conversion lift and burned $8,000 in ad spend, and the one registry rule that would have saved the month. The panel defines minimal metadata (objective, owner, primary signal), gives three plain-English micro-test templates, and offers a tech-optional recipe (one-sheet registry + suggest-only automation) plus a short explainer for hashed cohorts and privacy bands. The episode closes with a 21-day rollout checklist, acceptance tests, and three immediate plays listeners can run this week.
