Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent change in the system. Has there been any significant update or deployment to the Distributed Order Management module in the past month?

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 change-related issues; if no, we'd look at gradual degradation factors.

• Considering the nature of distributed systems, I'm curious about the scale. Has there been a sudden increase in order volume or system load recently?

Why it matters: Increased load can expose latent issues in distributed systems. Expected answer: Order volume has increased by 20% this month. Impact on approach: High load would lead us to investigate scalability and resource allocation.

• Given that this is a distributed system, I'm wondering about network stability. Have there been any reported network issues or changes in infrastructure?

Why it matters: Network problems can significantly impact distributed systems. Expected answer: No major network changes reported. Impact on approach: If network issues are present, we'd prioritize infrastructure investigation.

• Thinking about the user experience, I'm interested in the error patterns. Are these errors consistent across all users or concentrated in specific segments or regions?

Why it matters: Localized issues might indicate problems with specific components or data centers. Expected answer: Errors are more prevalent in the Asia-Pacific region. Impact on approach: Regional concentration would lead us to investigate region-specific factors.
