Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent software update. Has there been any firmware or driver updates released in the past month?

Why it matters: Software changes often correlate with support spikes. Expected answer: Yes, a firmware update was released two weeks ago. Impact on approach: If confirmed, we'd focus on the update's contents and rollout process.

• Considering user segments, I'm curious about the nature of these calls. Are they coming primarily from new users or long-time customers?

Why it matters: Different user groups may indicate different root causes. Expected answer: Calls are evenly distributed between new and existing users. Impact on approach: We'd need to investigate issues affecting both user types.

• Given the printer's business focus, I'm wondering about any recent changes in market dynamics. Has there been a significant influx of new business customers recently?

Why it matters: A shift in user base could explain increased support needs. Expected answer: No unusual changes in customer acquisition rates. Impact on approach: We'd focus more on product-specific issues rather than user onboarding.

• Thinking about potential system changes, has there been any recent modifications to how support calls are logged or categorized?
