NPPE materials describe the design process as incorporating systematic technical measures to identify and mitigate risks to public safety and performance. Hazard analysis, failure analysis, and risk assessment are standard engineering and geoscience tools used to evaluate potential dangers, assess failure modes, and quantify risk during design and development.

Option D is correct because liability assessment is a legal and risk management consideration rather than a technical design safety measure. While professionals should be aware of liability implications, NPPE references clarify that liability assessment is not a standard technical step in the engineering design process.

Therefore, option D is the correct answer.
