Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be seasonal factors at play. Has there been any significant change in travel patterns or holiday bookings compared to the same period last year?

Why it matters: Seasonal trends could explain engagement drops and affect our solution approach. Expected answer: No significant changes in travel patterns compared to last year. Impact on approach: If confirmed, we'd focus more on internal factors or recent changes.

• Considering the specificity of the 15% drop, I'm curious about our measurement methods. Has there been any change in how we define or measure user engagement recently?

Why it matters: Ensures we're addressing a real issue, not a measurement anomaly. Expected answer: No changes in measurement methods. Impact on approach: If there were changes, we'd need to reassess the validity of the 15% figure.

• Given the mobile-specific nature of the drop, I'm wondering about platform differences. Is this 15% drop consistent across iOS and Android, or is it more pronounced on one platform?

Why it matters: Helps narrow down potential technical or UX issues. Expected answer: The drop is relatively consistent across platforms. Impact on approach: If platform-specific, we'd focus on that particular OS or app version.

• Thinking about recent updates, have there been any significant app releases or feature changes in the past 1-2 months?

Why it matters: Recent changes are often culprits in engagement shifts. Expected answer: A major update was released 6 weeks ago. Impact on approach: If confirmed, we'd scrutinize the changes in that update closely.

• Considering user segments, I'm curious if this drop is uniform across all user types. Are we seeing any differences in engagement changes between frequent travelers and occasional users?

Why it matters: Helps identify if the issue affects all users or specific segments. Expected answer: The drop is more pronounced among occasional users. Impact on approach: We'd focus on features and experiences most relevant to occasional users.
