Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
You are helping launch a new digital product and want to validate whether a new onboarding experience improves early user activation versus the current flow. The team is excited to move quickly, but you need an experiment design that can support a credible launch decision without harming the user experience.
How would you design an A/B test for this launch, including what you would measure, how you would size the test, and how you would decide whether the product is ready to ship?
