3. Our advice

Axiomatic design is based on a strong assumption: separate, decompose, divide, modularize, decouple... the system to be designed is always preferable. However, the relevance of such an assumption has been called into question. Designing is also about making clever syntheses, for example, by finding synergies between requirements, functions, modules, and so on. Indeed, Suh admits as much when he advocates integrating several functions into one component... without, however, axiomatizing how to do it! Suh's approach is therefore only relevant if the system to be (re)designed can be decomposed.
