Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent change in the platform. Has there been any significant update or deployment to Driverless AI 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 AI platforms, I'm curious about data quality. Have there been any changes in the input data sources or formats used by Driverless AI recently?

Why it matters: Data quality directly impacts AI model performance. Expected answer: No significant changes in data sources. Impact on approach: If yes, we'd investigate data pipeline; if no, we'd focus more on model and infrastructure issues.

• Given the 30% increase, I'm wondering about the distribution of errors. Is this increase uniform across all users and use cases, or is it concentrated in specific segments?

Why it matters: Helps narrow down the problem scope and identify patterns. Expected answer: The increase is more pronounced in certain user segments. Impact on approach: If uniform, we'd look at platform-wide issues; if segmented, we'd focus on specific use cases or user groups.

• Thinking about system load, has there been a significant increase in platform usage or the complexity of tasks being performed?

Why it matters: Increased load or complexity could strain system resources. Expected answer: Usage has remained relatively stable. Impact on approach: If usage increased, we'd investigate scaling issues; if stable, we'd focus more on internal system changes or external factors.
