Problem
Scenario
You work on a growth surface in a B2B SaaS product and launch a new onboarding prompt intended to improve activation. Early results look better in treatment, but you need to know whether the initiative actually caused the improvement rather than reflecting noise, mix shifts, or measurement issues.
Question
How would you determine whether the growth initiative truly caused an improvement? Walk through how you would design the experiment, define success, and decide whether the observed lift is real enough to ship.
Metrics to Define
- Primary: 7-day activation rate
- Guardrails: retained active accounts, frustration/dismissal rate, support contact rate
- Secondary: time to activation and segment cuts
Design Considerations
- Randomize at eligible_account_id
- Use 50/50 allocation
- Run long enough for a full 7-day outcome window
- Stratify by acquisition channel and company size
