During the COVID-19 crisis, organizations had to demonstrate organizational resilience (OR) to continue to carry out their missions. We conducted qualitative research to identify the factors that contributed to the OR of police and penitentiary institutions in French-speaking Switzerland, in terms of their operations and management. The modes of action and crisis responses of these emergency services, regularly confronted with crises and particularly impacted during the pandemic, are worthy of attention. To this end, we synthesized the OR factors that are frequently identified in both theoretical and empirical review articles and identified four theoretical conceptualizations: (a) resilience engineering, (b) ecological resilience (these two are the most widely used), (c) a third way situating resilience at an intermediate stage in a metamodel representing the evolution of organizations from a fragile to antifragile state, and (d) a conceptualization focusing on the temporal dimension of OR. Based on the results of 25 semi-structured interviews with executives from cantonal police forces and prisons, we present what we consider to be the key levers in a three-phase resilience process (upstream, during, and after the shock): anticipatory and proactive organizational culture, information management and communication, liminal leadership practices, social and environmental practices, agility-enhancing governance practices, and learning capabilities. Our results largely confirm that these parameters significantly contributed to the OR of the institutions in question. They also enable us to propose winning configurations of factors that can increase the potential for OR.
