Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a seasonal component. Has this increase in declines coincided with any particular events or time of year?

Why it matters: Seasonal patterns could indicate external factors rather than internal issues. Expected answer: No clear seasonal pattern identified. Impact on approach: If seasonal, we'd focus on capacity planning; if not, we'll dig deeper into internal factors.

• Considering user segments, I'm wondering if this is affecting all users equally. Have you noticed any patterns in terms of user demographics or usage frequency?

Why it matters: Segmentation could reveal targeted issues rather than system-wide problems. Expected answer: Higher decline rates among infrequent users. Impact on approach: If segmented, we'd investigate onboarding and reactivation processes; if universal, we'd look at core system issues.

• Thinking about recent changes, has there been any significant update to the payment processing system or card issuance process in the last quarter?

Why it matters: Recent changes often correlate with performance shifts. Expected answer: A minor update to the fraud detection algorithm was implemented. Impact on approach: If changes occurred, we'd focus on rollback or optimization; if not, we'd explore external factors more thoroughly.

• Considering data integrity, has there been any change in how transaction declines are measured or reported?

Why it matters: Ensures we're dealing with a real issue, not a reporting anomaly. Expected answer: No changes in measurement or reporting methods. Impact on approach: If changed, we'd audit the reporting system; if not, we'd proceed with analyzing the actual decline rates.
