A/B Test Design: Redesigned Onboarding Flow

Context

A consumer subscription app is launching a redesigned onboarding flow for newly registered users. The goal is to increase user activation. For clarity, define activation as: a new user starts playing any title within 7 days of signup (adjust if your organization uses a different definition).

Task

Design an A/B test for the new onboarding. Specify:

Hypothesis
Unit of randomization
Key (primary/secondary) metrics
Guardrail metrics and thresholds
Sample size/power and runtime calculation
Sequential monitoring approach
Decision framework if early results show activation uplift but an increase in support tickets
