Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent change in the supply chain. Has there been any significant alteration in our manufacturing or logistics processes in the past 3-6 months?

Why it matters: Recent changes could directly impact delivery performance. Expected answer: Yes, we've implemented a new inventory management system. Impact on approach: If confirmed, we'd focus on system integration and process adaptation.

• Considering the specificity of the 30% decline, I'm wondering about our measurement accuracy. Has there been any change in how we calculate or track on-time delivery rates?

Why it matters: Ensures we're addressing a real issue, not a measurement anomaly. Expected answer: No changes in measurement methodology. Impact on approach: If unchanged, we'd focus on operational issues rather than data discrepancies.

• Given the complexity of the LEAP engine, I'm curious about part specificity. Are we seeing this decline across all spare parts or specific components?

Why it matters: Helps narrow down potential causes to specific production lines or suppliers. Expected answer: The decline is more pronounced in certain high-complexity components. Impact on approach: Would guide us to investigate specific production processes or supplier relationships.

• Considering potential external factors, have there been any significant changes in customer demand patterns or order volumes recently?

Why it matters: Sudden demand fluctuations could strain the supply chain. Expected answer: Slight increase in demand, but within forecasted ranges. Impact on approach: If demand is stable, we'd focus more on internal processes and supplier management.
