Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a seasonal factor at play. Has there been any change in prescription patterns or health insurance enrollment cycles that could explain this spike?

Why it matters: Seasonal trends could significantly impact our root cause analysis and solution approach. Expected answer: No significant seasonal changes noted. Impact on approach: If seasonal, we'd focus on capacity planning; if not, we'd look deeper into internal factors.

• I'm curious about recent system changes. Have there been any updates to the pharmacy benefit management platform or related systems in the past 1-2 months?

Why it matters: System changes often correlate with sudden metric shifts. Expected answer: A minor update was pushed two weeks before the spike. Impact on approach: If confirmed, we'd prioritize technical investigations and rollback considerations.

• Regarding user segments, are we seeing this increase across all demographics, or is it concentrated in specific groups?

Why it matters: Segmentation helps narrow down potential causes and tailor solutions. Expected answer: The increase is more pronounced among older adults. Impact on approach: We'd focus on issues specific to this demographic, like complex medication regimens or technology barriers.

• I'm wondering about any changes in call categorization or routing. Has there been any modification to how calls are classified or directed within the customer service system?

Why it matters: Changes in classification could artificially inflate numbers without an actual increase in issues. Expected answer: No recent changes to call categorization or routing. Impact on approach: If changed, we'd audit the classification system; if not, we'd focus on actual call drivers.
