Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent change in the system. Has there been any significant update to the delivery routing algorithm in the past month?

Why it matters: Recent changes often correlate with performance shifts. Expected answer: Yes, there was an update to optimize routes. Impact on approach: If confirmed, we'd focus on algorithm analysis and potential rollback.

• Considering user segments, I'm curious about order patterns. Have you noticed any shift in order volume or distribution across different areas of the city?

Why it matters: Changes in order patterns could strain certain delivery zones. Expected answer: There's been a 15% increase in orders from suburban areas. Impact on approach: We'd investigate delivery capacity in affected areas.

• Thinking about external factors, I'm wondering about recent weather conditions. Has there been any unusual weather patterns affecting road conditions in the past month?

Why it matters: Adverse weather can significantly impact delivery times. Expected answer: There have been more rainy days than usual. Impact on approach: We'd factor in weather-related delays and potential mitigations.

• Considering operational aspects, I'm interested in driver availability. Has there been any change in the number of active delivery drivers compared to the previous month?

Why it matters: Driver shortage could directly impact delivery times. Expected answer: Driver numbers have remained stable. Impact on approach: We'd shift focus to other factors if driver availability isn't the issue.
