To resolve this shortcoming, Renato de Fusco set about analysing the development of the phenomenon of design in different cultures, through the lens of an “historiographic artifice”, which considers design as a single corpus, characterised by four structural parameters: the project, production, retail and consumption. That is, when project quality grows thanks to the training of schools and designers, when attention to production can be seen in the details, when the distribution networks and media dare to present and publicly discuss the latest products, and when the public sanctions their quality by buying them, then, and only then, will the four-leaf clover, the quadrifoglio, open up and display its full splendour. Where those four moments – the project, production, retail and consumption, come together in unison, that is when we will have good design.
