Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be related to a recent system update. Has there been any significant changes or deployments to the order management system in the past 1-2 weeks?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, there was a minor update last week. Impact on approach: If confirmed, we'd focus on the update's components and rollback options.

• Considering the scale of the drop, I'm wondering about potential data processing bottlenecks. Can you provide more details on which specific parts of the order processing pipeline are most affected?

Why it matters: Pinpointing the affected areas helps narrow down potential causes. Expected answer: The slowdown is primarily in the order validation stage. Impact on approach: We'd investigate data validation processes and related databases.

• Given the nature of e-commerce, I'm curious about any recent spikes in order volume. Have there been any unusual patterns in order volume or types in the past week?

Why it matters: Unexpected volume changes can strain system capacity. Expected answer: Order volume has been consistent with previous weeks. Impact on approach: If true, we'd focus more on internal system issues rather than external factors.

• Thinking about potential data integrity issues, has there been any change in how throughput is measured or reported in the past week?

Why it matters: Ensures we're working with accurate data and not chasing a non-existent problem. Expected answer: No changes to measurement or reporting methods. Impact on approach: Confirms the issue is real and not a reporting anomaly.
