4. Mistakes to avoid

Do not dissociate functional requirements – and more broadly functional reasoning in terms of for what? – from physical parameters – or reasoning in terms of how?

Do not systematically prioritize all design parameters (functional requirements, physical parameters).

The belief that the hardest part of axiomatic design is understanding the formalisms. But this approach leaves many empirical questions in the dark: what is a functional requirement? What is decoupling? What, in concrete terms, is the information content of a solution?

The axiomatic design of a system whose structure cannot be decomposed!
