Social practices is a theoretical framework and analytical approach within social theory that conceptualizes patterned, routinized ways of doing things as the fundamental units of social life. This concept investigates how practices, understood as bundles of interconnected elements comprising materials, meanings, and competences, are performed, reproduced, and transformed, providing a lens to analyze the dynamics of social phenomena, including consumption, technology diffusion, and sustainability transitions, by focusing on the collective performance and change of these activity bundles rather than solely on individual actors or macro-level structures.
