Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a seasonal factor. Has there been any significant change in order volume or patterns compared to the same quarter last year?

Why it matters: Seasonal fluctuations could explain increased complaints if the system is overwhelmed. Expected answer: Order volume has increased by 15% compared to last year. Impact on approach: If confirmed, we'd need to focus on scalability solutions.

• Considering user segments, I'm curious about the distribution of complaints. Are we seeing a higher proportion of complaints from any particular user group or geographic area?

Why it matters: This could indicate localized issues or problems affecting specific user segments. Expected answer: Complaints are evenly distributed across user segments and regions. Impact on approach: If uneven, we'd prioritize addressing issues for the most affected segments.

• Regarding recent changes, have there been any updates to the tracking system or related infrastructure in the past quarter?

Why it matters: Recent changes could be directly responsible for the increase in complaints. Expected answer: A new tracking algorithm was implemented six weeks ago. Impact on approach: If confirmed, we'd focus on reviewing and potentially rolling back recent changes.

• Thinking about the complaint metric itself, has there been any change in how complaints are categorized or recorded?

Why it matters: Changes in measurement could artificially inflate the complaint numbers. Expected answer: No changes have been made to the complaint categorization system. Impact on approach: If changes were made, we'd need to reassess the validity of the 20% increase.
