• Looking at the timing, I'm thinking there might be a recent system change. Has there been any significant update or deployment to the notification system in the past 1-2 months?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, there was a system upgrade. Impact on approach: If yes, we'd focus on the upgrade's impact; if no, we'd look at other factors.

• Considering the scale of the drop, I'm wondering about the affected user base. Is this 15% drop consistent across all user segments or concentrated in specific groups?

Why it matters: Helps determine if it's a systemic issue or limited to certain users. Expected answer: The drop is more pronounced in certain user groups. Impact on approach: If segmented, we'd investigate those specific user groups; if uniform, we'd look at system-wide factors.

• Given the critical nature of emergency notifications, I'm curious about any changes in message content or format. Have there been any alterations to the message structure or delivery protocols recently?

Why it matters: Changes in message format could affect delivery rates. Expected answer: No significant changes to message format. Impact on approach: If changed, we'd examine the new format's impact; if not, we'd look at other technical factors.

• Thinking about external factors, I'm considering potential changes in network infrastructure. Have there been any reported issues with major telecom providers or changes in network protocols?

Why it matters: External network changes could impact delivery rates. Expected answer: No major reported network issues. Impact on approach: If yes, we'd collaborate with network providers; if no, we'd focus more on internal systems.
