Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a seasonal factor. Has this increase in returns coincided with any specific weather changes or events?

Why it matters: Seasonal factors could explain the sudden spike and inform our solution approach. Expected answer: No significant seasonal changes noted. Impact on approach: If confirmed, we'd focus more on internal factors.

• Considering product quality, I'm wondering if there have been any recent changes to the AIRism fabric or manufacturing process. Have any modifications been made to the product in the last few months?

Why it matters: Product changes could directly impact customer satisfaction and return rates. Expected answer: Minor updates to the fabric composition were implemented two months ago. Impact on approach: This would shift our focus to product-related hypotheses.

• Thinking about customer expectations, has there been any recent marketing campaign or product positioning that might have set different expectations for the AIRism t-shirts?

Why it matters: Misaligned expectations could lead to increased returns. Expected answer: A new campaign highlighting "enhanced comfort" was launched last month. Impact on approach: We'd need to investigate the alignment between marketing messages and product performance.

• Considering the return process itself, have there been any changes to the return policy or procedure in recent weeks?

Why it matters: Simplified returns could lead to increased return rates without necessarily indicating product issues. Expected answer: No changes to the return policy have been made. Impact on approach: This would rule out policy-related causes and focus our attention on product or customer-related factors.
