• Looking at the timing, I'm thinking there might have been a recent change in the service. Has WumDrop implemented any new features or processes in the last month?

Why it matters: Recent changes often correlate with sudden shifts in customer satisfaction. Expected answer: Yes, a new delivery routing algorithm was implemented. Impact on approach: If confirmed, we'd focus on technical issues and user experience related to the new system.

• Considering the magnitude of the drop, I'm wondering about the sample size. How many reviews contribute to these ratings, and has the volume changed recently?

Why it matters: Ensures the data is statistically significant and not skewed by a small sample. Expected answer: Approximately 1000 reviews per week, consistent over time. Impact on approach: If consistent, we'd focus on widespread issues rather than isolated incidents.

• Given the nature of grocery delivery, I'm curious about any seasonal factors. Have there been any unusual weather patterns or events in the past two weeks?

Why it matters: External factors can significantly impact delivery services. Expected answer: No significant weather events, typical for the season. Impact on approach: If confirmed, we'd focus more on internal factors rather than external disruptions.

• Considering potential changes in user behavior, has there been any shift in order patterns or peak times?

Why it matters: Changes in demand can strain systems and affect service quality. Expected answer: A 20% increase in evening orders. Impact on approach: If confirmed, we'd investigate capacity issues during peak hours.
