Clarifying Questions (3 minutes)

• I'm noticing the issue is specific to this quarter. Has there been any significant product update or system change recently?

Why it matters: Recent changes could be directly linked to the increased error rate. Expected answer: Yes, we rolled out a new database system last month. Impact on approach: If confirmed, we'd focus on the new system's integration and performance.

• Looking at the error patterns, are they concentrated in specific property types or geographical areas?

Why it matters: This could indicate issues with data sources or regional system differences. Expected answer: Errors seem more prevalent in commercial property listings in urban areas. Impact on approach: We'd investigate potential data inconsistencies or capacity issues in affected regions.

• Considering user behavior, have we seen any changes in how frequently users are updating or adding listings?

Why it matters: Increased activity could strain the system, leading to more errors. Expected answer: There's been a 20% increase in listing updates over the past month. Impact on approach: We'd examine if the system can handle the increased load and consider optimizing for higher volumes.

• Regarding the error rate metric, has there been any change in how we're measuring or defining errors?

Why it matters: A change in measurement could explain the apparent increase without actual performance degradation. Expected answer: No changes to the error rate definition or measurement system. Impact on approach: We'd focus on actual performance issues rather than metric definition discrepancies.
