Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be a recent change. Has there been any significant update to the digital library platform in the past two weeks?

Why it matters: Recent changes often correlate with sudden metric shifts. Expected answer: Yes, a minor UI update was rolled out. Impact on approach: If yes, we'd focus on change-related hypotheses; if no, we'd look at external factors or gradual issues that reached a tipping point.

• Considering user segments, I'm curious about the distribution. Is this 30% decrease uniform across all user types, or is it more pronounced in specific segments?

Why it matters: Helps narrow down if it's a universal issue or segment-specific. Expected answer: The decrease is more significant among new users. Impact on approach: If segment-specific, we'd focus on that user journey; if uniform, we'd look at platform-wide issues.

• Given the specificity of the 30% figure, I'm wondering about our measurement systems. Have there been any changes to how we track or calculate ebook downloads recently?

Why it matters: Ensures we're not dealing with a data anomaly rather than an actual decrease. Expected answer: No changes to tracking systems. Impact on approach: If there were changes, we'd audit the data collection process; if not, we'd focus on actual download behavior.

• Thinking about the broader context, has there been any significant change in our marketing efforts or content offerings in the past month?

Why it matters: Changes in promotion or content can significantly impact download rates. Expected answer: A major promotion ended two weeks ago. Impact on approach: If yes, we'd investigate the correlation between marketing activities and download rates; if no, we'd focus more on technical or user experience issues.
