Good design (leaving apart the subjective angle) is only an element or output of usability – in practical sense. Otherwise, it’s more like a philosophy. Usability done with a philosophy of good design, would make it effective, error-tolerant, engaging, etc. This part I echo. My argument is towards the literal aspect about the myth, that a good design brings usability. In a way, this has a resemblance to myth #4: usability is User Experience. A good user interface design is not going to save a product if it is not useful or low on performance or erroneous. The usability and acceptance of such products have no connection with the presence or absence of good design.
L'utilisabilité comme une philosophie et non comme un requis? Cette approche me ressemble. C'est un peu comme exiger la qualité lorsqu'elle est plutôt le résultat d'un effort commun par une culture qui l'inspire.
