Design a profit growth strategy

You operate a ride-sharing business. Lay out a specific plan to grow profit in the coming quarter while setting the service apart from traditional street-hail taxis. In particular:

1. Rank five profit levers—such as pricing, driver incentives, matching/ETAs, acquisition/retention, and cost control—and estimate the expected impact of each using rough, back-of-the-envelope figures.
2. Specify success metrics and guardrails, for example contribution margin per ride, driver online utilization, cancellation rate, wait time, and supply fill rate.
3. Describe the relationship between supply–demand elasticity and surge pricing, and outline how you would estimate price elasticity from historical data versus from a controlled experiment.
4. Design a single A/B test to validate a pricing or incentive change, covering target segments, randomization unit, key metrics, minimal detectable effect, and safeguards against marketplace imbalance.
5. Give two recommendations you would launch first, along with their risks and how you would monitor for cannibalization of non-surge hours.

Overview: This question assesses a data scientist’s skills in product analytics, marketplace economics, pricing strategy, demand elasticity estimation, experimentation, and quantitative impact sizing.
