Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent change in the system. Has there been any recent deployment or update to the Payments platform in the last 1-2 weeks?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, there was a minor update. Impact on approach: If yes, I'd focus on change management and rollback considerations.

• Considering the specificity of ACH transactions, I'm wondering about the scope. Is this increased error rate affecting all ACH transactions or specific types (e.g., credits vs. debits)?

Why it matters: Helps narrow down the problem area. Expected answer: It's primarily affecting ACH credits. Impact on approach: I'd focus on credit-specific processes and integrations.

• Given the nature of financial transactions, I'm curious about any changes in regulatory requirements. Have there been any recent updates to ACH processing regulations?

Why it matters: Regulatory changes can impact transaction processing. Expected answer: No recent regulatory changes. Impact on approach: If no, I'd shift focus to internal factors.

• Thinking about system dependencies, I'm considering external integrations. Have there been any reported issues with banking partners or the ACH network itself?

Why it matters: External dependencies can cause cascading issues. Expected answer: No reported external issues. Impact on approach: If no, I'd concentrate on internal systems and processes.
