Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent system change. Has there been any software updates or infrastructure modifications in the past 1-2 months?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, a software update was implemented 6 weeks ago. Impact on approach: If confirmed, we'd focus on regression testing and rollback options.

• Considering user segments, I'm curious about the distribution of the issue. Is the 15% drop uniform across all user groups or concentrated in specific segments?

Why it matters: Helps narrow down potential causes and target solutions. Expected answer: The drop is more pronounced in high-volume users. Impact on approach: We'd investigate factors specific to heavy users, like account management or frequency-based issues.

• Given the nature of electronic toll systems, I'm wondering about hardware components. Have there been any reports of malfunctioning transponders or toll booth equipment?

Why it matters: Hardware issues could explain transaction failures. Expected answer: No significant increase in hardware failure reports. Impact on approach: If true, we'd shift focus to software and user behavior aspects.

• Thinking about external factors, has there been any change in traffic patterns or road usage in the past month?

Why it matters: External changes could impact transaction volume. Expected answer: No significant changes in overall traffic patterns. Impact on approach: If confirmed, we'd focus more on internal system issues rather than external factors.
