Clarifying Questions (5 mins)

• Looking at the product context, I'm thinking about the specific engine components we're targeting. Could you provide more details on which parts we're focusing on for improvement through additive manufacturing?

Why it matters: Different components have varying requirements and constraints, affecting our approach to optimization. Expected answer: We're primarily focusing on turbine blades and fuel nozzles. Impact on approach: Would tailor material selection and design optimization strategies for these specific components.

• Considering user behavior, I'm curious about the current adoption rate of additively manufactured parts in GE Aviation's engines. What percentage of components in our latest engine models are produced using additive manufacturing?

Why it matters: Helps gauge the maturity of our additive manufacturing processes and potential for expansion. Expected answer: Currently, about 30% of components in our latest engine models use additive manufacturing. Impact on approach: Would focus on scaling up adoption if the percentage is low, or refining existing processes if it's already high.

• Examining external factors, I'm wondering about the regulatory landscape. How have recent changes in aviation safety regulations impacted the certification process for additively manufactured engine components?

Why it matters: Regulatory compliance is crucial in aviation and can significantly influence our manufacturing approach. Expected answer: New regulations require more extensive testing and documentation for additively manufactured parts. Impact on approach: Would prioritize solutions that streamline the certification process while maintaining or improving safety standards.

• Considering the product lifecycle, where are we in terms of additive manufacturing technology maturity at GE Aviation? Are we in an early adoption phase or a more mature optimization stage?

Why it matters: Determines whether we focus on fundamental process improvements or incremental optimizations. Expected answer: We're in a mid-maturity stage, with established processes but significant room for improvement. Impact on approach: Would balance innovative new techniques with refinement of existing processes.
