Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be a recent change. Has there been any significant product update or operational change in the past week?

Why it matters: Recent changes often correlate with performance shifts. Expected answer: Yes, a new routing algorithm was implemented. Impact on approach: If confirmed, I'd focus on technical issues related to the new system.

• Considering user segments, I'm curious if this affects all order types equally. Are we seeing differences in on-time rates between, say, express and standard deliveries?

Why it matters: Helps isolate whether the issue is universal or specific to certain order types. Expected answer: Express deliveries are more affected than standard ones. Impact on approach: I'd investigate factors specific to express delivery processes.

• Given the geographic focus, I'm wondering about external factors. Have there been any significant changes in Berlin's traffic patterns or road works this week?

Why it matters: External factors could explain citywide delivery delays. Expected answer: No major changes reported. Impact on approach: If confirmed, I'd shift focus to internal factors.

• Thinking about operational capacity, has there been any change in the number of delivery personnel or their availability this week?

Why it matters: Staffing issues directly impact delivery capabilities. Expected answer: Slight decrease in available drivers. Impact on approach: I'd investigate workforce management and recruitment strategies.

• Considering data integrity, I'm curious about our measurement systems. Has there been any change in how we track or calculate on-time deliveries?

Why it matters: Ensures we're dealing with a real issue, not a measurement anomaly. Expected answer: No changes to measurement systems. Impact on approach: Confirms focus on actual performance, not data discrepancies.
