 Complete the following phrase:  Supply chain resilience is the capacity of a supply chain to persist, adapt, or transform in the face of change. For a long time, the interpretation of resilience in the sense of engineering resilience  robustness prevailed in supply chain management, leading to the notion of persistence. A popular implementation of this idea is given by measuring the time-to-survive and the time-to-recover of the supply chain, allowing identification of weak points in the system. More recently, the interpretations of resilience in the sense of ecological resilience and socialecological resilience have led to the notions of adaptation and transformation, respectively. A supply chain is thus interpreted as a social-ecological system that  similar to an ecosystem e.g. forest  is able to constantly adapt to external environmental conditions and  through the presence of social actors and their ability to foresight  also to transform itself into a fundamentally new system. This leads to a panarchical interpretation of a supply chain, embedding it into a system of systems, allowing to analyze the interactions of the supply chain with systems that operate at other levels e.g. society, political economy, planet Earth. For example, these three components of resilience can be discussed for the
