Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent change in the product formulation. Has there been any alteration to the Herbal Tea Concentrate recipe in the last 1-2 months?

Why it matters: Changes in formulation could directly impact taste and efficacy, leading to increased complaints. Expected answer: Yes, there was a minor ingredient change. Impact on approach: If confirmed, we'd focus on the specific change and its potential effects.

• Considering the scale of the increase, I'm wondering about the distribution of complaints. Are these complaints concentrated in specific geographic regions or spread evenly across all markets?

Why it matters: Regional concentration could indicate localized issues like supply chain problems or cultural preferences. Expected answer: Complaints are primarily from the Western region. Impact on approach: We'd investigate region-specific factors if complaints are localized.

• Given the nature of the product, I'm curious about seasonality. Is this 30% increase unusual when compared to the same month in previous years?

Why it matters: Seasonal factors could explain fluctuations in customer satisfaction. Expected answer: This increase is abnormal compared to previous years. Impact on approach: If seasonal, we'd look into environmental factors or changing consumer behaviors.

• Considering potential system issues, has there been any recent change in how customer complaints are collected or categorized?

Why it matters: Changes in data collection could artificially inflate complaint numbers. Expected answer: No recent changes to the complaint system. Impact on approach: If changed, we'd need to re-evaluate the validity of the 30% increase.
