the data says ship — your gut says no

the challenge

your a/b test wrapped with statistically significant results: the new checkout flow increased conversion by 4.2% on a 95% confidence interval. four weeks of clean data, no anomalies. every dashboard looks green. your engineering lead is asking to ship Monday. but something doesn't sit right. the session recordings show users hesitating at step 3 in a way that the metric doesn't capture. support tickets are slightly up in the test group — not enough to kill the numbers, but there. and one power user emailed in saying the new flow "feels off, like it's rushing me."

shipping Monday means hitting a Q2 metric that your team needs to hit. delaying another two weeks means missing it. your CEO has been asking about this experiment in the weekly all-hands for three weeks.
