Metricswarm-up

You shipped a new onboarding flow for a photo-editing app. How do you know it is working?

How to approach it

Define what a successful onboarding outcome is, such as editing and saving a first photo, and compare users who got the new flow with those who did not.

How a strong answer opens

“I'd first define a successful onboarding, say saving or sharing a first edit, and then compare people who got the new flow with people who didn't.”

Outline of a strong answer

Try answering out loud for a few minutes before you open this.

  1. Define activation: first edit saved or shared
  2. Primary metric: activation rate within the first day
  3. Secondary: time to first edit, onboarding completion
  4. Downstream: week-one retention
  5. Compare with a control group or a clean before-and-after
  6. Watch for guardrails like support tickets

Where this question usually goes wrong

Calling the flow a success because more people finished onboarding, without checking whether they edited photos or came back.
