Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be seasonal factors at play. Has this decline been consistent throughout the year, or are there specific months where it's more pronounced?

Why it matters: Seasonal patterns could indicate external factors rather than product issues. Expected answer: The decline has been relatively consistent. Impact on approach: If seasonal, we'd focus on year-over-year comparisons and external factors.

• Considering user segments, I'm curious about the impact across different demographics. Are we seeing this decline uniformly across all user groups, or is it more pronounced in certain segments?

Why it matters: Helps identify if the issue is widespread or specific to certain user types. Expected answer: The decline is more significant among younger users. Impact on approach: We'd focus on understanding changes in preferences or behaviors of specific user groups.

• Thinking about recent changes, have there been any significant updates to the web browser version in the past year that might correlate with this decline?

Why it matters: Product changes could directly impact user behavior. Expected answer: A new UI was implemented six months ago. Impact on approach: We'd investigate the impact of specific product changes on user engagement.

• Considering the metric itself, has there been any change in how we measure or define "average reading time per session" in the last year?

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