Clarifying Questions (3 minutes)

• Looking at the sudden drop, I'm thinking there might be a technical issue. Have there been any recent updates to our QR code system or payment processing infrastructure?

Why it matters: Technical issues often cause abrupt changes in metrics. Expected answer: Information about recent system updates or lack thereof. Impact on approach: If there were updates, we'd focus on technical root causes; if not, we'd explore other factors more deeply.

• Considering user behavior, I'm curious about any changes in merchant onboarding or training. Has there been any shift in how we educate merchants about QR transactions?

Why it matters: Changes in merchant understanding could lead to decreased usage. Expected answer: Details on recent changes in merchant education or support. Impact on approach: If there were changes, we'd investigate the effectiveness of our merchant support; if not, we'd look more into user experience issues.

• Thinking about market dynamics, have there been any significant moves by competitors or changes in the regulatory environment recently?

Why it matters: External market forces can dramatically impact user behavior. Expected answer: Information on competitor actions or regulatory changes. Impact on approach: If there were external changes, we'd need to consider how to adapt our product; if not, we'd focus more on internal factors.

• Considering the metric itself, has there been any change in how we define or measure QR code transactions?

Why it matters: Changes in measurement can create false impressions of performance shifts. Expected answer: Confirmation of consistent measurement methods or details of recent changes. Impact on approach: If there were changes in measurement, we'd need to recalibrate our analysis; if not, we'd proceed with our current understanding of the metric.
