Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be related to a recent product update. Have there been any changes to the customs clearance service in the past two weeks?

Why it matters: Recent changes often correlate with sudden metric shifts. Expected answer: Yes, a minor UI update was released. Impact on approach: If yes, I'll focus on the update's impact; if no, I'll explore other internal factors.

• Considering the scale of the increase, I'm wondering about the affected user segments. Is this increase uniform across all customer types, or is it concentrated in specific segments?

Why it matters: Helps narrow down potential causes and affected areas. Expected answer: Primarily affecting small to medium-sized businesses. Impact on approach: If segmented, I'll focus on that user group; if uniform, I'll look at broader system issues.

• Given the nature of customs clearance, I'm curious about any recent regulatory changes. Have there been any significant customs policy updates in our key markets recently?

Why it matters: External factors could be driving the increase in support tickets. Expected answer: No major policy changes reported. Impact on approach: If yes, we'll need to adapt our service; if no, we'll focus more on internal factors.

• Thinking about our support system, I'm wondering if there have been any changes in how we categorize or route tickets. Has our ticketing system or categorization process changed recently?

Why it matters: Could indicate a measurement issue rather than a true increase in problems. Expected answer: No changes to the ticketing system. Impact on approach: If changed, we'll need to validate our data; if not, we can trust the reported increase.
