Clarifying Questions (3 minutes)

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

Why it matters: Recent changes often correlate with support spikes. Expected answer: Yes, a major update was rolled out. Impact on approach: If yes, we'd focus on the update's features and potential bugs.

• Considering user segments, I'm curious about the distribution of these tickets. Are we seeing this increase across all customer types, or is it concentrated in specific segments?

Why it matters: Helps identify if it's a universal issue or segment-specific. Expected answer: The increase is primarily in enterprise customers. Impact on approach: If segment-specific, we'd tailor our investigation to that user group.

• Given the nature of WMS, I'm wondering about seasonality. Is this 30% increase unusual for this time of year, or do we typically see fluctuations in support tickets seasonally?

Why it matters: Rules out normal seasonal variations. Expected answer: This increase is atypical for the season. Impact on approach: If seasonal, we'd compare to historical data for context.

• Thinking about the support process, has there been any change in how support tickets are categorized or processed in the last month?

Why it matters: Ensures the increase isn't due to measurement changes. Expected answer: No changes to the support ticket system. Impact on approach: If changed, we'd need to recalibrate our analysis based on the new system.
