In 2009, university lecturers and designers Anthony Dunne and Fiona Raby published A/B¹ , the first manifesto on critical design. In a simple table, they contrast two different perspectives on design practice. (b) is by no means intended to replace (a), but simply to show another dimension that can be discussed and compared. Column (a) contains terms such as usability, ergonomics, and consumer, which are closely associated with the industrially dominated understanding of design. In the second column, Dunne & Raby present opposites such as ethics, rhetoric, and citizen. With these pairs of opposites, the two authors outline a design programme in extremely reduced form, in which design is no longer merely used to make products sexy, consumable, and user-friendly. Instead, it becomes a critical medium in which technological, political, and social developments are addressed and reflected upon. The discussion or dialogue between position (a) and position (b) is presented within the posters.
