Clarifying Questions (3 minute)

• Looking at the timing, I'm thinking there might be seasonal factors at play. Has this decrease coincided with any major weather changes or events in urban areas?

Why it matters: Seasonal patterns could explain temporary changes in driving behavior. Expected answer: No significant weather anomalies reported. Impact on approach: If weather isn't a factor, we'll focus more on app-specific or user behavior changes.

• Considering user segments, I'm curious about the demographics. Has there been any shift in the user base composition, particularly new vs. long-term users?

Why it matters: Different user groups may have distinct usage patterns. Expected answer: No major changes in user demographics. Impact on approach: If user composition is stable, we'll investigate changes in existing user behavior or app functionality.

• Regarding performance metrics, I'm wondering about the reliability of our data collection. Have there been any recent changes to how trip duration is calculated or recorded?

Why it matters: Ensures we're not dealing with a data anomaly rather than a real behavioral change. Expected answer: No changes to data collection or calculation methods. Impact on approach: If data integrity is confirmed, we'll focus on actual usage patterns and potential external factors.

• Thinking about recent updates, have there been any significant changes to the app's features or user interface in the last quarter?

Why it matters: App changes could directly impact user behavior and trip recording. Expected answer: Minor UI updates, no major feature changes. Impact on approach: If no significant changes, we'll look more closely at external factors or subtle UI impacts.
