📊 Example Comparisons

<details> <summary><strong>Phase C Purpose</strong></summary>

Model	Response Snippet
Base LLaMA-3.1	“Phase C covers detailed design and preparations for manufacturing…” (generic)
Fine-Tuned	“The main purpose is to complete the detailed design of system elements, fabricate hardware, and code software, ensuring all end products are defined for integration.”

</details>

<details> <summary><strong>Verification vs. Validation</strong></summary>

Model	Response Snippet
Base LLaMA-3.1	“Verification checks requirements; validation checks user needs…” (too brief)
Fine-Tuned	“Verification ensures the system meets specified requirements; validation confirms it satisfies stakeholder expectations in its intended environment.”

⚠️ Limitations

—Scope Bounded: Content based on the 2018 handbook; may omit newer updates.
—Hallucinations: Possible on out-of-handbook queries.
—Bias: NASA-specific terminology; verify critical engineering decisions against official documents.
