Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a seasonal component. Has this 30% drop been compared to the same period last year?

Why it matters: Seasonal fluctuations could explain the drop without indicating a deeper problem. Expected answer: Yes, it's been compared and is still significantly lower. Impact on approach: If seasonal, we'd focus on optimizing for this period; if not, we'd investigate other factors.

• Considering user segments, I'm curious if this drop is uniform across all service categories. Are some categories more affected than others?

Why it matters: Uneven impact could point to category-specific issues or changes in user behavior. Expected answer: The drop varies across categories, with some more affected than others. Impact on approach: We'd prioritize investigating the most impacted categories first.

• Thinking about recent changes, have there been any updates to the Instant Book feature or related systems in the past 1-2 months?

Why it matters: Recent changes could directly correlate with the booking drop. Expected answer: A minor UI update was implemented 6 weeks ago. Impact on approach: We'd scrutinize the update's impact on user behavior and booking flow.

• Considering data integrity, has there been any change in how bookings are tracked or reported in the last month?

Why it matters: Ensures we're not chasing a phantom problem due to measurement issues. Expected answer: No changes to tracking or reporting systems. Impact on approach: If changes occurred, we'd first validate the data before deeper analysis.
