Clarifying Questions (3 minutes)

• Looking at the failure rate, I'm wondering about the scope. Is this 40% failure rate consistent across all user segments and devices, or are there specific groups more affected?

Why it matters: Identifying patterns in affected users helps narrow down potential causes. Expected answer: The issue is more prevalent on older mobile devices and in regions with slower internet connections. Impact on approach: This would shift focus to device compatibility and network optimization.

• Considering recent changes, have there been any updates to the Avatar creation process or underlying technology in the past few weeks?

Why it matters: Recent changes often correlate with sudden performance shifts. Expected answer: A new facial recognition algorithm was implemented two weeks ago. Impact on approach: This would prioritize investigating the new algorithm's performance and integration.

• Thinking about user behavior, has there been any change in how users are interacting with the Avatar feature recently?

Why it matters: User behavior shifts can sometimes explain performance changes. Expected answer: There's been a surge in Avatar usage due to a viral trend. Impact on approach: This would lead to exploring scalability and load handling capabilities.

• Regarding data integrity, can we confirm that the 40% failure rate is accurately measured and consistently defined across all systems?

Why it matters: Ensures we're solving a real problem, not a measurement issue. Expected answer: The metric is consistently defined, but there might be discrepancies in how different systems log failures. Impact on approach: This would necessitate a data audit before proceeding with other investigations.
