Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be related to recent system changes. Have there been any significant updates or deployments to the treasury management system in the past quarter?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, there was a major update. Impact on approach: If yes, we'd focus on the changes made; if no, we'd look at external factors or gradual degradation.

• Considering the scale of the increase, I'm wondering about data volume changes. Has there been a substantial increase in the amount of data being processed by the system recently?

Why it matters: Increased data volume could strain system resources. Expected answer: Data volume has grown by 20% in the last quarter. Impact on approach: If yes, we'd investigate scaling solutions; if no, we'd look at other internal factors.

• Given the nature of treasury management, I'm curious about market volatility. Has there been an unusual increase in market volatility or transaction frequency during this period?

Why it matters: External market conditions could impact processing requirements. Expected answer: Market volatility has been within normal ranges. Impact on approach: If yes, we'd consider optimizing for high-volatility scenarios; if no, we'd focus more on internal factors.

• Thinking about system architecture, I'm wondering about dependencies. Have there been any changes or issues with external systems or APIs that the treasury management system interacts with?

Why it matters: External dependencies can significantly impact system performance. Expected answer: No major changes reported in external systems. Impact on approach: If yes, we'd investigate integration points; if no, we'd focus more on the core system itself.
