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 Security Manager in the past month?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, there was a minor update two weeks ago. Impact on approach: If confirmed, we'd focus on changes introduced in that update.

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

Why it matters: Helps narrow down potential causes related to specific use cases or environments. Expected answer: The issue seems more prevalent in enterprise customers. Impact on approach: We'd investigate enterprise-specific configurations or usage patterns.

• Given the nature of the feature, I'm curious about the volume of rules being processed. Has there been any significant change in the number or complexity of security rules being managed recently?

Why it matters: Increased load or complexity could strain the system. Expected answer: There's been a 20% increase in rule volume over the past quarter. Impact on approach: We'd examine scalability and performance under increased load.

• Thinking about external factors, I'm considering if there have been any changes in the broader IT security landscape. Have there been any major security events or compliance changes that might have altered how customers are using the rule cleanup feature?

Why it matters: External events can dramatically change usage patterns. Expected answer: No significant external events noted. Impact on approach: We'd focus more on internal factors if external influences are ruled out.
