##### Scenario DoorDash plans to launch a bike-courier delivery option and wants to assess whether, where, and how to roll it out successfully. ##### Question From DoorDash’s perspective, why launch a bike delivery option? What criteria would define success for the bike feature? How would you decide whether to launch in all markets or focus on urban/downtown areas? Which metrics (short-term, long-term, guardrail) would you track to judge success? How would you evaluate the feature’s impact, accounting for network effects? Describe how you would design and run an A/B test to measure the feature’s effectiveness. What data would you gather to assess downtown market suitability? ##### Hints Consider marketplace balance for consumers, dashers, restaurants, efficiency, cost, delivery time, pilot-market choice, and robust experiment design.

This question evaluates a data scientist's competency in product analytics, experimentation, marketplace economics, causal inference, metrics definition, and unit-economics assessment for a new delivery feature.

Assess Success Criteria for Bike-Courier Delivery Launch

Scenario

DoorDash plans to launch a bike-courier delivery option and wants to assess whether, where, and how to roll it out successfully.

Task

As the data scientist leading this, address the following:

Why launch a bike delivery option from DoorDash’s perspective? Who benefits and how?
What criteria would define success for the bike feature (customers, dashers, merchants, platform economics)?
How would you decide between launching in all markets versus focusing on urban/downtown areas?
Which metrics would you track to judge success?
- Short-term (immediate operational/experience effects)
- Long-term (retention, network growth, unit economics)
- Guardrails (safety, quality, marketplace balance)
How would you evaluate the feature’s impact while accounting for marketplace/network effects (multi-sided platform dynamics)?
How would you design and run an A/B test (or alternative experiment) to measure effectiveness, including unit of randomization, spillover controls, power, and analysis plan?
What data would you gather to assess downtown market suitability for bikes?

Hint: Consider marketplace balance for consumers, dashers, and restaurants; efficiency, cost, delivery time, pilot-market choice, and robust experiment design.
