Clarifying Questions (3 minutes)

• Based on Trainline's business model, I'm thinking revenue might be tied to ticket sales volume. Could you confirm if Trainline earns a commission on each ticket sold?

Why it matters: Helps understand the financial incentives behind prioritizing different search results. Expected answer: Yes, Trainline earns a percentage commission on ticket sales. Impact on approach: Would influence whether to prioritize higher volume (cheaper tickets) or higher value (potentially faster, more expensive routes).

• Considering user behavior, I'm assuming there might be distinct user segments with different preferences. Do we have data on the split between price-sensitive and time-sensitive users?

Why it matters: Informs how we might balance the needs of different user groups. Expected answer: Roughly 60% price-sensitive, 40% time-sensitive. Impact on approach: Would guide the design of personalized search results or user preference settings.

• From a technical perspective, I'm wondering about the complexity of implementing dynamic search result ordering. How feasible would it be to personalize results based on user preferences or behavior?

Why it matters: Determines if a more nuanced solution is possible beyond a binary choice. Expected answer: Technically feasible but would require significant development effort. Impact on approach: Might lead to a phased implementation strategy or A/B testing of different approaches.

• Regarding timeline, I'm curious about any upcoming seasonal peaks in travel bookings. Are there any major events or holidays we need to consider in our decision timeline?

Why it matters: Helps prioritize the urgency of the decision and potential implementation. Expected answer: Summer holiday season is approaching in 3 months. Impact on approach: Might accelerate the decision-making process to capture peak booking periods.
