Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent change in our system. Has there been any significant update or deployment to Templafy's infrastructure in the past week?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, there was a minor update to the template rendering engine. Impact on approach: If confirmed, we'd focus on the recent changes as a primary area of investigation.

• Considering user segmentation, I'm curious about the distribution of these support tickets. Are they coming from a specific subset of users or spread across our entire user base?

Why it matters: This helps determine if it's a global issue or limited to certain user groups. Expected answer: The tickets are primarily from enterprise clients with large template libraries. Impact on approach: We'd prioritize investigating scalability issues for large-scale implementations.

• Thinking about performance metrics, I'm wondering if we've seen any changes in our server response times or CPU usage. Have our monitoring systems flagged any unusual patterns recently?

Why it matters: This could indicate whether the issue is server-side or client-side. Expected answer: There's been a 30% increase in server response times during peak hours. Impact on approach: We'd focus on server-side optimizations and capacity planning.

• Considering potential external factors, I'm curious if there have been any changes in how users are interacting with templates. Have we rolled out any new template features or seen a shift in template complexity?

Why it matters: User behavior changes can sometimes lead to unexpected performance issues. Expected answer: No new features, but there's been an increase in template complexity from some key clients. Impact on approach: We'd investigate how complex templates impact loading times and consider optimization strategies.
