Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a seasonal factor. Has there been any significant change in Brazilian eating habits or food trends in the past 2 months?

Why it matters: Seasonal changes could explain the sudden drop and inform our recovery strategy. Expected answer: No major seasonal shifts noted. Impact on approach: If confirmed, we'd focus more on internal factors or competitive landscape.

• Considering the magnitude of the decline, I'm wondering about competitive activity. Have any major competitors launched new products or aggressive marketing campaigns recently?

Why it matters: A strong competitive move could explain the market share loss. Expected answer: A new local brand has gained traction with a health-focused campaign. Impact on approach: We'd need to analyze our positioning and potentially adjust our marketing strategy.

• Given the specific 30% figure, I'm curious about our measurement methods. Has there been any change in how we calculate market share or collect data in the past 3 months?

Why it matters: Ensures we're dealing with accurate data and not a measurement anomaly. Expected answer: No changes in measurement methodology. Impact on approach: If confirmed, we can confidently proceed with our analysis of external and internal factors.

• Thinking about product quality, have there been any changes to our recipe, packaging, or production process in the last quarter?

Why it matters: Internal changes could have unintended consequences on product perception or quality. Expected answer: A new eco-friendly packaging was introduced 10 weeks ago. Impact on approach: We'd need to investigate if the packaging change has affected product quality or consumer perception.
