Design & semiotics Translated from Guibourgé Jérôme, Design phase 1, améliorer sa conception, L’Harmattan, Paris, 2021[Guibourgé Jérôme, "Design et sémiologie" in Design phase 1, améliorer sa conception, L’Harmattan, Paris, 2021, pp. 162-181]

Is there a common theoretical reference frame which puts design as scientific discipline, or design in practice is only a recycling of other disciplines? From the conception of project versus object and from the definition of design by Findeli, we show that design is essentially combinations of theoretical concepts from a variety of technical and scientific disciplines without being a recycling involving a devaluation of theoretical components used. Each design is thought as a production of meaning, a dockable event in the semio-narrative conception of discursive syntax. Design as autonomous scientific field, can not be based on neither (1) the separation between practice and theory nor the theoretical elements summoned but (2) falls under their combinations which intervene in a meliorative way on their meanings. The common design culture must be sought not in loans to various disciplines but in a semiotics of its practices and theorisation of the implementations relations.
