To overcome this weak situation, Renato de Fusco began to analyze the development of the design phenomenon in different cultures in light of a “historiographical artifice”, which considers design as a unitary corpus characterized by four structural parameters: project, production, sale and consumption. That is, when the quality of design is enhanced by the training of schools and designers, when attention to production is evident in the details, when distribution networks and media dare to present and publicly discuss new products, and when the public validates the quality of the products offered through their purchases, then, and only then, does the four-leaf clover, the quadrifoglio, open and reveal itself in all its splendor. Wherever these four moments—design, production, sales, and consumption—come together in unison, we will find good design.
