Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be a recent change. Has there been any system update or deployment in the last week?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, a minor update was pushed 3 days ago. Impact on approach: If true, I'd focus on rollback options and code review.

• Considering the scale, I'm wondering about user segmentation. Is this increase uniform across all user segments or concentrated in specific groups?

Why it matters: Helps narrow down potential causes and affected areas. Expected answer: The issue is more prevalent among SMB customers. Impact on approach: I'd investigate SMB-specific integrations or usage patterns.

• Given the nature of recurring payments, I'm curious about the payment cycle. Are these failures happening at a particular point in the payment process?

Why it matters: Pinpoints where in the transaction flow the problem occurs. Expected answer: Failures are primarily at the authorization stage. Impact on approach: I'd focus on authorization protocols and bank integrations.

• Thinking about external factors, have there been any recent regulatory changes or bank policy updates that might affect recurring payments?

Why it matters: External changes can significantly impact fintech operations. Expected answer: No major regulatory changes, but one partner bank updated its API. Impact on approach: I'd investigate compatibility issues with the updated bank API.
