Resilience (glossary)

the capability of a system with specific characteristics before, during and after a disruption to absorb the disruption, recover to an acceptable level of performance, and sustain that level for an acceptable period of time (INCOSE Resilient Systems Working Group, 2010). For this definition the systems of interest include only human-made systems. Characteristics can be static features, such as redundancy, or dynamic features, such as corrective action to be specified. Before, during and after – allows the three phases of disruption to be considered. Before – Allows anticipation and corrective action to be considered. During – How the system survives the impact of the disruption. After – How the system recovers from the disruption. Some sources use the term “resiliency”; however, most sources have adopted the term “resilience”.
