Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent product change. Has there been any significant update to the virtual debit card feature in the last 1-2 months?

Why it matters: Recent changes often correlate with metric shifts. Expected answer: Yes, a UI update was implemented. Impact on approach: If yes, we'd focus on the change's impact; if no, we'd look at external factors.

• Considering user segments, I'm wondering if this drop is uniform across all user groups. Can you provide a breakdown of the activation rate decline by user demographics or acquisition channels?

Why it matters: Helps identify if the issue is global or specific to certain user groups. Expected answer: The decline is more pronounced among new users. Impact on approach: If segmented, we'd tailor solutions to specific groups; if uniform, we'd look at system-wide issues.

• Given the metric specificity, I'm curious about the definition. Has there been any change in how we define or measure the "activation rate" for virtual debit cards?

Why it matters: Ensures we're comparing apples to apples in our analysis. Expected answer: No changes in metric definition. Impact on approach: If changed, we'd need to recalibrate our analysis; if not, we can proceed with historical comparisons.

• Considering potential technical issues, have there been any reported problems with the card activation process or related systems in the past month?

Why it matters: Technical glitches can directly impact activation rates. Expected answer: Some intermittent errors reported. Impact on approach: If yes, we'd prioritize technical investigations; if no, we'd focus more on user behavior and product design.
