Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a correlation with recent system changes. Have there been any significant updates or deployments to the platform in the last 1-2 months?

Why it matters: Recent changes could directly impact processing speed. Expected answer: Yes, there was a major update to the transaction processing module. Impact on approach: If confirmed, we'd focus on the recent changes and their effects.

• Considering the scale of the slowdown, I'm wondering about the distribution. Is the 15% drop consistent across all types of transactions, or are certain transaction types more affected?

Why it matters: Helps identify if the issue is systemic or specific to certain operations. Expected answer: The slowdown is more pronounced in complex, multi-step transactions. Impact on approach: We'd investigate the specific transaction types and their processing paths.

• Given the nature of banking systems, I'm curious about any changes in transaction volume or patterns. Has there been a significant increase in the number or complexity of transactions processed recently?

Why it matters: Increased load or changing usage patterns could strain the system. Expected answer: Transaction volume has increased by 20% due to a new partnership. Impact on approach: We'd focus on scalability and load handling capabilities.

• Thinking about external factors, I'm considering potential infrastructure changes. Have there been any modifications to the underlying hardware, network, or cloud infrastructure?

Why it matters: Infrastructure changes could impact overall system performance. Expected answer: No significant infrastructure changes in the past three months. Impact on approach: We'd shift focus to software and configuration issues.
