An economic downturn reduces discretionary rides by 20% for six months. As PM lead for core ride-hailing, propose a plan to preserve market share and margins. Recommend pricing and incentive adjustments, product changes to retain core users, strategies to manage driver supply, and a prioritized roadmap including experiments and contingency plans.

Sample Answer

Clarify objective & constraints: short-term shock (six months), goal = preserve market share and margins while protecting core user retention and driver availability. Measure: weekly active riders, trips/week, GMV, margin %, driver churn, wait time, fill rate, CAC, LTV.

High-level approach: defend core riders with targeted demand stimulation, protect margins via optimized pricing, reduce churn via product touches, and stabilize driver supply with flexible incentives and cost management.

1) Pricing & incentives (near-term, data-driven)- Introduce targeted time-limited discounts for core users (frequency-based: riders with >X trips/month) rather than blanket promos. Use promo caps per user to control spend.- Dynamic micro-pricing: widen surge/discount floor bands by micro-segments (city, time, rider elasticity) to maintain margin. A/B test elasticities.- Shift driver incentives from guaranteed hourly pay to trip-completion bonuses and streak rewards to encourage active supply while capping fixed costs.Metric: incremental trips per $1 promo; margin impact per cohort.

2) Product changes to retain core users- “Commit & Save” subscription for frequent riders: pay monthly for X discounted rides, priority pickup — locks in revenue and reduces sensitivity.- Improve reliability: ETA accuracy, driver matching to reduce wait times. Low-effort UX improvements: saved pickup spots, scheduled rides.- Frictionless refunds/credits for delays to maintain trust.

3) Driver supply management- Flexible hour marketplace: let part-time drivers pick guaranteed micro-shifts with small guaranteed earnings + completion bonuses.- Reduce idle churn: provide short-term perks (fuel/maintenance partners, microloans) prioritized in cities showing supply stress.- Optimize dispatch to increase driver utilization and reduce empty miles (routing + pooling where margin allows).

4) Prioritized roadmap (90-day sprints)Sprint 0 (weeks 0–2): Analytics sprint — segment riders by elasticity, map driver supply stress by city. Define KPI targets.Sprint 1 (w1–w4): Launch targeted promo pilot + A/B test dynamic micro-pricing in 3 markets. Quick subscription MVP pilot in 1 city. Start driver micro-shift trials.Sprint 2 (w5–w8): Expand successful pricing tests; roll subscription to top 10 markets; deploy driver retention package; implement dispatch tweaks.Sprint 3 (w9–w12): Optimize, rollout nationwide, prepare contingency triggers.

Experiments & success criteria:- Promo A: cost per incremental trip < LTV-derived threshold and < historical CPA.- Subscription conversion >5% of frequent cohort; retention lift +10%.- Driver fill rate >95% in target windows; wait time delta < +10%.

Contingency plans- If demand falls faster: tighten promo spend, accelerate subscriptions, introduce tighter minimum fares.- If driver supply collapses: temporarily increase targeted driver guarantees in affected zones, or limit low-margin products (pooling) to preserve availability.- If margins compress beyond threshold: prioritize high-LTV segments, sunset broad discounts, introduce service tiers.

Cross-functional execution: weekly PM-led war-room with analytics, ops, marketing, finance; 2-week sprint cadences; clear KPI dashboards and read-only alert triggers for contingency activation.

This plan balances short-term demand stimulation with margin discipline, locks in core users via subscription & reliability, and stabilizes driver supply with flexible, controllable incentives.

Design an A/B experiment to test a new surge-smoothing pricing algorithm that aims to reduce price volatility while keeping average wait times stable. Define the primary hypothesis, primary and guardrail metrics, sampling strategy, sample-size considerations, mitigation for geographic spillover, and key risks to monitor.

Sample Answer

Primary hypothesis:- Introducing the surge-smoothing pricing algorithm will reduce short-term price volatility (peak-to-trough price swings) by ≥20% without increasing rider average wait time by more than 5% compared to control.

Primary & guardrail metrics:- Primary treatment metric: Price volatility (e.g., standard deviation of surge multiplier per zone per 15-min window).- Primary outcome metric: Average rider wait time.- Guardrails: - Rider experience: cancellation rate, booking conversion, NPS (survey). - Driver economics: driver earnings per hour, driver active time. - Business: gross bookings, take rate, regional revenue. - Safety/operations: incidents reported, support tickets.

Sampling strategy:- Unit: rider-trip request (randomize at user-request level) but stratify by region × time-of-day to balance demand patterns.- Random assign cohorts at device-ID (or account) for persistence over experiment period to avoid cross-treatment confusion.- Run for multiple demand cycles (minimum 4 weeks) to capture weekly patterns.

Sample-size considerations:- Power to detect 20% reduction in volatility and <5% change in wait time. Use historical volatility and wait-time variance to compute N with 80–90% power, α=0.05. Expect larger N for volatility metric; pilot A/A for variance estimation then finalize N. Account for cluster effects if randomizing by zone.

Mitigation for geographic spillover:- Prefer within-zone randomization with user-level assignment. If drivers can move across zones, create buffer zones where experiment not run, or block-randomize by contiguous region (cluster randomization) with matched-pair controls. Monitor driver repositioning flows and, if necessary, restrict treatment to zones where driver movement is limited.

Key risks to monitor:- Driver churn or reduced supply (leading to longer-term wait increases).- Adverse selection: high-value drivers dropping out.- Learning effects causing temporary volatility changes.- Spillover bias via driver movement.- Measurement drift (telemetry, time sync).- Regulatory/PR risk if prices perceived as opaque.

Implementation notes:- Pre-register analysis plan, define primary metric window, use difference-in-differences and CUPED for variance reduction, run A/A test before launch, and stop early only on pre-specified safety triggers (e.g., >10% increase in wait time or >5% drop in driver earnings).

Lyft emphasizes cultural values like being 'user-first' and 'doing the right thing.' Describe how understanding Lyft's culture would influence your approach to prioritizing features as a Product Manager. Give two concrete examples of feature trade-offs you might make differently because of culture and why.
