Clarifying Questions (3 minutes)

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

Why it matters: Seasonal trends could explain the drop and affect our solution approach. Expected answer: Yes, it's been compared and is still significant. Impact on approach: If seasonal, we'd focus on why this year is different; if not, we'd look at recent changes.

• Considering our user segments, I'm curious about the geographic distribution. Has the decrease been uniform across all regions, or are certain areas more affected?

Why it matters: Regional variations could point to localized issues or market-specific challenges. Expected answer: The decrease is more pronounced in certain regions. Impact on approach: We'd prioritize investigating region-specific factors if there's significant variation.

• Thinking about recent changes, have there been any updates to the application process or marketing campaigns in the past month?

Why it matters: Recent changes could directly impact application rates. Expected answer: A new application interface was launched two weeks ago. Impact on approach: We'd focus on analyzing the new interface's impact on user behavior.

• Regarding our performance metrics, has there been any change in how we're tracking or defining "new teacher applications" recently?

Why it matters: Ensures we're not dealing with a data anomaly or definition change. Expected answer: No changes in tracking or definition. Impact on approach: If changed, we'd need to recalibrate our analysis; if not, we can proceed with our current understanding.
