-
For each aspect, propose one concrete improvement:
- What exactly would you change or add?
- How would it integrate into the user experience?
- Justify expected user and business impact. State hypotheses, trade-offs, and risks.
-
Outline how you would measure success post-launch:
- Primary, secondary, and guardrail metrics
- Experiment design (randomization unit, power, segments, duration)
Keep answers concise but analytical; use examples and metrics.
