Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be related to a recent system update. Has there been any significant changes to the EFT payment system in the past two weeks?

Why it matters: System changes often have unintended consequences on performance. Expected answer: Yes, there was a minor update to improve transaction speed. Impact on approach: If confirmed, we'd focus on regression testing and rollback options.

• Considering user segments, I'm curious if this drop is uniform across all user types. Are we seeing any patterns in terms of which users are experiencing more failed transactions?

Why it matters: Segmentation could reveal targeted issues rather than system-wide problems. Expected answer: The drop seems more pronounced among new users. Impact on approach: We'd investigate onboarding processes and new user experience if confirmed.

• Given the specific 15% drop, I'm wondering about our metric definition. Has there been any change in how we calculate or measure the EFT payment success rate?

Why it matters: Ensures we're comparing apples to apples and not chasing a data anomaly. Expected answer: No changes to the metric definition or measurement system. Impact on approach: If changed, we'd need to recalibrate our analysis based on the new definition.

• Considering external factors, have there been any significant changes in the financial ecosystem or regulations that might affect EFT payments?

Why it matters: External factors could explain the drop and require different solutions. Expected answer: No major external changes noted. Impact on approach: If external factors are involved, we'd need to adapt our product to new market conditions.
