When is design, we find those characteristics and values of "design culture" that regard design processes and methods, designers' skills and attitudes.

In the Introduction of Ocula 24 we investigate the conditions that favour the emergence of design processes typical of design and of its evolution, up to social design which, by overcoming incremental and inertial innovations, drives radical social innovations.
