More conversions but more returns: ship or not?
An e-commerce team tests a more aggressive checkout flow that pre-selects add-ons and speeds people through payment. The primary metric, purchase conversion, is up a significant +1.5%. But a guardrail, the 30-day return-and-refund rate, is up a significant +0.8 percentage points, and customer-support contacts ticked up slightly.
Should the team ship, and how should they reason about the guardrail regression?
