@ARTICLE{10.21494/ISTE.OP.2023.0952, TITLE={When the armor does not make the soldier: Why do we need design fiction?}, AUTHOR={Nicolas Minvielle, Olivier Wathelet, }, JOURNAL={Technology and Innovation}, VOLUME={8}, NUMBER={Issue 2}, YEAR={2023}, URL={https://openscience.fr/When-the-armor-does-not-make-the-soldier-Why-do-we-need-design-fiction}, DOI={10.21494/ISTE.OP.2023.0952}, ISSN={2399-8571}, ABSTRACT={This paper presents the way in which fiction can be used within the framework of an innovation project, in particular an innovation project with a long-term perspective. We first present the role of fictional worlds and the way in which their mapping by lineages allows us to understand the evolution of forms, technologies and uses for products or services. We then explain, whilst highlighting the example of the French army’s Red Team Defense, how fictional productions can become performative, or how they can have an impact on a given audience.}}
