Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a seasonal factor. Has this 30% drop been compared to the same period last year?

Why it matters: Seasonal trends could explain engagement fluctuations. Expected answer: No significant seasonal variation observed. Impact on approach: If seasonal, we'd focus on optimizing for cyclical patterns.

• Considering user segments, I'm curious if this drop is uniform across all user types. Have we seen any particular user segment more affected than others?

Why it matters: Identifies if the issue is widespread or localized to specific users. Expected answer: The drop is more pronounced among first-time users. Impact on approach: We'd prioritize onboarding and first-time user experience improvements.

• Thinking about recent changes, have there been any updates to the valuation algorithm or UI in the past month?

Why it matters: Recent changes could directly impact user engagement. Expected answer: A minor UI update was implemented three weeks ago. Impact on approach: We'd scrutinize the UI changes and their potential impact on usability.

• Regarding data integrity, has there been any change in how we measure or define user engagement for this tool?

Why it matters: Ensures we're comparing apples to apples in our metrics. Expected answer: No changes in measurement or definition. Impact on approach: If changed, we'd need to recalibrate our analysis based on the new metrics.
