Preserving resilience while managing changes, an assessment framework

Technological or managerial changes aim to improve socio-technical systems' performance, general productivity, profitability, or quality. In some circumstances, changes can affect, as a side effect, system safety properties and facilitate the occurrence of crises or by decreasing system ability to mitigate crises. Anticipating potential consequences of change on socio-technical systems' safety properties requires knowledge, method, and tools covering socio-technical' complexity. This paper presents a Resilience Engineering-based methodological framework aiming to support the identification of the impact of a change on individual and collective behaviours within the perspective of safety management.
