Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be related to a recent update. Has there been any app update or server-side change deployed in the past week?

Why it matters: Recent changes are often the culprit for sudden performance issues. Expected answer: Yes, there was an update. Impact on approach: If yes, we'll focus on the changes in that update. If no, we'll look at external factors or gradual issues that may have reached a tipping point.

• Considering user segments, I'm wondering if this is affecting all users equally. Are we seeing the crash rate increase across all user segments, or is it concentrated in specific groups?

Why it matters: This helps us narrow down whether it's a universal issue or specific to certain users or devices. Expected answer: The issue is more prevalent in certain user segments. Impact on approach: If it's segment-specific, we'll focus on those segments' unique characteristics or usage patterns.

• Given the severity of the increase, I'm curious about the impact on user engagement. Have we seen a corresponding drop in daily active users or session lengths?

Why it matters: This helps quantify the business impact and urgency of the issue. Expected answer: Yes, there's been a noticeable decrease in engagement metrics. Impact on approach: A significant impact on engagement would prioritize quick fixes over more comprehensive but time-consuming solutions.

• Thinking about potential external factors, has there been any significant change in network conditions or third-party services we rely on?

Why it matters: External dependencies can often cause unexpected issues. Expected answer: No major changes reported in external services. Impact on approach: If external factors are ruled out, we'll focus more on internal issues within our control.
