Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent change that triggered this issue. Have there been any significant updates to the platform or backend systems in the past week?

Why it matters: Recent changes often correlate with sudden performance shifts. Expected answer: Yes, there was a minor update to the transaction processing system. Impact on approach: If confirmed, we'd focus on the recent change as a primary suspect.

• Considering the nature of expense management, I'm curious about the transaction volume trends. Has there been an unusual spike in transaction attempts compared to previous weeks?

Why it matters: Unusual activity could strain the system, leading to failures. Expected answer: Transaction volume is within normal range. Impact on approach: If volume is normal, we'd shift focus to internal system issues rather than capacity problems.

• Given the criticality of financial transactions, I'm wondering about the error patterns. Are the failed transactions showing any consistent error messages or occurring at specific steps in the process?

Why it matters: Consistent error patterns can quickly narrow down the problem area. Expected answer: There's a recurring "timeout" error for a subset of transactions. Impact on approach: This would guide us to investigate network or database response times.

• Considering the diverse user base of expense management platforms, I'm curious about the user segmentation. Is this issue affecting all users equally, or are certain types of users or companies experiencing higher failure rates?

Why it matters: Segmented issues often point to specific configuration or integration problems. Expected answer: The issue seems to affect users from larger enterprises more frequently. Impact on approach: We'd investigate enterprise-specific features or integrations as potential causes.
