Conditional Design is a design method formulated by the graphic designers Luna Maurer, Jonathan Puckey, Roel Wouters and the artist Edo Paulus, in which conditions and rules of play are drawn up that invite cooperation within a 'regulated' process towards an unpredictable design or result. The book Conditional Design sets out to provide insight into the method in an exciting way and to invite others to apply the method themselves.
