Confrontation of institutional logics and dynamics of organizational routines.

Summary The article deals with the evolution of routines in organizations confronted with the coexistence of institutional logics. The case studied [1] is that of tele-assistance companies for the frail elderly, which articulate in their activity a logic of medical care and a logic of social care. The authors show that the ambiguity and uncertainty of the situations to be managed are at the origin of tensions in the activity, and generate a dynamic of routines. These tensions are linked to the coexistence of logics. Some of the new routines constructed hybridize the logics, others appear and are linked to a less specific logic, that of social care.
