• Looking at the timing, I'm thinking there might have been a recent change in customer service processes. Has Musinsa implemented any new customer service policies or technologies in the past month?

Why it matters: Recent changes often correlate with sudden metric shifts. Expected answer: Yes, a new chatbot was implemented. Impact on approach: If confirmed, I'd focus on chatbot performance and integration.

• Considering the magnitude of the drop, I'm wondering about the sample size. How many customer ratings contribute to this average score?

Why it matters: Ensures the change is statistically significant and not due to a small sample. Expected answer: Approximately 10,000 ratings per week. Impact on approach: If the sample is small, I'd investigate potential sampling biases.

Why it matters: External factors can significantly impact customer service demand and satisfaction. Expected answer: A flash sale occurred in the first week of the decline. Impact on approach: If confirmed, I'd analyze the impact of increased order volume on customer service.

• Noticing the precise star rating, I'm thinking about the rating system itself. Has there been any change to how the satisfaction rating is calculated or displayed to customers?
