Define metrics for new market expansion success

## Scenario DoorDash is expanding into a **new geographic market**. Leadership asks: “What data should we focus on, and how do we evaluate market health and performance in the first 6 months?” ## Task 1. Propose a **metric framework** to evaluate a new market launch: - Primary success metrics - Diagnostic metrics (to understand *why* performance changes) - Guardrail metrics (to prevent harming users/partners/unit economics) 2. Outline a **6-month evaluation plan** (what you’d check in weeks 1–2, month 1, months 2–3, months 4–6). 3. Explain key pitfalls (e.g., seasonality, marketing bursts, survivorship bias, supply/demand feedback loops) and how you’d adjust your analysis to make decisions. Assume a 3-sided marketplace (consumers, dashers, merchants) and that early performance is influenced by promotions and constrained supply onboarding.
