Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be a recent change. Has there been any significant product update or feature release in the past two weeks?

Why it matters: Recent changes often correlate with sudden metric shifts. Expected answer: Yes, a new UI was rolled out. Impact on approach: If yes, we'd focus on the changes; 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 decrease uniform across all user segments or concentrated in specific groups?

Why it matters: Helps identify if it's a global issue or specific to certain users. Expected answer: The decrease is more pronounced in first-time users. Impact on approach: If segmented, we'd focus on that specific user group; if uniform, we'd look at broader, system-wide issues.

• Given the severity, I'm wondering about data accuracy. Have there been any changes to our analytics setup or sign-up flow recently?

Why it matters: Ensures we're not chasing a phantom problem due to data discrepancies. Expected answer: No changes to analytics, but a new onboarding flow was implemented. Impact on approach: If analytics changed, we'd validate data first; if not, we'd investigate product changes.

• Considering market dynamics, has there been any significant competitor activity or market shift in the past week?

Why it matters: External factors can sometimes explain internal metrics. Expected answer: No major competitor moves, but a government health initiative was announced. Impact on approach: If yes, we'd factor in market dynamics; if no, we'd focus more on internal factors.
