• Looking at the timing, I'm thinking there might be a recent system update. Has there been any significant software deployment or infrastructure change in the past month?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, a new version was deployed three weeks ago. Impact on approach: If confirmed, we'd focus on regression testing and rollback considerations.

• Considering user segments, I'm curious about the distribution of errors. Are we seeing this increase across all types of claims, or is it concentrated in specific areas?

Why it matters: Helps narrow down potential causes and affected user groups. Expected answer: The increase is primarily in complex claims involving multiple providers. Impact on approach: We'd investigate the logic handling complex claims and inter-provider communication.

• Thinking about data integrity, I'm wondering if there have been any changes in how we're measuring or defining error rates?

Why it matters: Ensures we're comparing apples to apples in our metrics. Expected answer: No changes in measurement or definition. Impact on approach: Confirms the issue is with the system, not the metrics.

• Considering external factors, have there been any recent regulatory changes or updates from insurance partners that might impact claims processing?
