Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be related to a recent deployment. Has there been any significant update or change to the document automation tool in the past week?

Why it matters: Recent changes often correlate with sudden performance shifts. Expected answer: Yes, there was a minor update to improve processing speed. Impact on approach: If confirmed, we'd focus on the changes made in that update.

• Considering user segments, I'm wondering if this is affecting all users equally. Are we seeing this spike across all customer types, or is it concentrated in specific segments?

Why it matters: Helps narrow down if it's a global issue or specific to certain use cases. Expected answer: The spike is more pronounced for enterprise customers. Impact on approach: We'd prioritize investigating enterprise-specific features or workflows.

• Given the nature of document automation, I'm curious about the types of documents involved. Is the error rate increase consistent across all document types, or are certain formats more affected?

Why it matters: Different document types might be processed differently, pointing to specific failure points. Expected answer: PDF documents show a higher error rate than others. Impact on approach: We'd focus on the PDF processing pipeline and recent changes there.

• Thinking about system load, I'm considering if there's been any unusual activity. Have we seen any significant changes in usage patterns or volume of documents processed recently?

Why it matters: Unusual load could stress the system beyond its normal operating parameters. Expected answer: There's been a 20% increase in document volume over the past month. Impact on approach: We'd investigate scalability issues and potential bottlenecks in our infrastructure.
