Which one of these statements is false when constructing robust models?

The statement regarding using the model for a one-off design project is considered false in the context of constructing robust models. Robust models are intended to be flexible and adaptable to changes, serving not just the immediate design needs but also potential future requirements. Designing with future modifications in mind ensures that the model can efficiently accommodate alterations without necessitating a complete overhaul, which is essential for maintaining efficiency and reducing redundancy in engineering practices.

In contrast, the other statements emphasize practices that enhance model robustness. Utilizing standardized naming conventions promotes clarity and consistency, making it easier for others to understand and work with the model. Incorporating comprehensive documentation is crucial as it serves as a reference for users to understand design intentions and decisions, which can significantly aid in future modifications or troubleshooting. Therefore, focusing on long-term utility and adaptability is key to model robustness, making the notion of treating a design as merely a "one-off project" contrary to best practices in model construction.
