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 data analytics solution 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 the changes made; if no, we'd look at external factors or gradual degradation.

• Considering the nature of data analytics, I'm curious about data volume. Has there been a substantial increase in the amount of data being processed recently?

Why it matters: Increased data volume could strain system resources. Expected answer: Data volume has grown by 30% in the last quarter. Impact on approach: If yes, we'd investigate scaling solutions; if no, we'd look at other potential bottlenecks.

• Given the specificity of "performance issues," I'm wondering about the exact nature of these issues. Are we seeing slower query response times, system crashes, or something else?

Why it matters: Different types of performance issues point to different root causes. Expected answer: Primarily slower query response times and occasional timeouts. Impact on approach: This would guide our technical investigation towards database optimization or query efficiency.

• Thinking about user segments, I'm curious if this is affecting all users equally. Are there any patterns in terms of which customers or types of analytics tasks are most affected?

Why it matters: Segmentation can reveal whether the issue is universal or specific to certain use cases. Expected answer: Enterprise customers running complex queries are most affected. Impact on approach: This would focus our efforts on optimizing for high-complexity use cases and large datasets.
