Juliette Brun, Pierrick Rivière, Emilie Boukaiba, Tevy Sault, Cyrille Lemaire, Alexandre Dingreville, David MorizetABSTRACT:
Bridging the intention-action gap is key to driving sustainable consumer behavior. In this paper, we introduce the Change Factory, a methodology that applies behavioral science to design sustainable product experiences. We detail its four-step CODE framework – Change, Obstacles, Design, and Experimentation – and illustrate its application on fragrance refill. After identifying behavioral barriers, 33 gentle intervention ideas were generated to promote refill adoption, validating the method’s efficacy in translating behavioral insights into concrete, behavior-driven design solutions.
