Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be seasonal factors at play. Have we seen similar dips in average transaction value during this quarter in previous years?

Why it matters: Seasonal patterns could explain the decrease and inform our solution approach. Expected answer: No significant seasonal patterns observed in previous years. Impact on approach: If seasonal, we'd focus on adapting to cyclical changes; if not, we'd investigate other factors.

• Considering user segments, I'm curious about the distribution of this decrease. Is the 8% drop consistent across all user demographics, or are certain groups more affected?

Why it matters: Identifying specific affected segments could pinpoint the root cause more accurately. Expected answer: The decrease is more pronounced among younger users (18-35). Impact on approach: We'd focus on understanding changes in younger users' behavior or preferences.

• Thinking about recent changes, have there been any updates to the Interac Flash system or associated apps in the last quarter that might have affected user behavior?

Why it matters: Recent changes could directly impact user interaction with the product. Expected answer: A minor UI update was rolled out to the mobile app two months ago. Impact on approach: We'd investigate if the UI change has altered user perception or usage patterns.

• Regarding transaction limits, has there been any change in the maximum amount allowed for contactless payments?

Why it matters: Changes in transaction limits could directly affect average transaction values. Expected answer: No changes to transaction limits in the past year. Impact on approach: If limits changed, we'd focus on adapting to new regulations; if not, we'd look at other factors influencing transaction size.
