"Resilience engineering is about identifying and then enhancing the positive capabilities of people and organizations that allow them to adapt effectively and safely under varying circumstances. Resilience is not about reducing negatives (incidents, errors, violations)."

"Resilience engineering is based on the premise that we are not custodians of already safe systems. Complex systems do not allow us to draw up all the rules by which they run, and not all scenarios they can get into are foreseeable."
2/8

"Systems are not inherently safe: they need to operate under competitive pressure, having to meet multiple conflicting goals at the same time, and always with limited resources. People and organizations have to create safety under these dynamic circumstances."

"Resilience engineering wants to understand and enhance how people themselves build, or engineer, adaptive capacities into their system, so that systems keep functioning under varying circumstances and conditions of imperfect knowledge."
4/8

"How do they create safety—by developing capacities that help them anticipate and absorb pressures, variations, and disruptions?"
5/8

"Resilience engineering is inspired by a range of fields beyond traditional safety disciplines, such as physical, organizational, psychological, and ecological sciences."
6/8

"The organic systems studied in these fields are effective (or not) at adjusting when they recognize a shortfall in their adaptive capacity—which is key to the creation of resilience (or its disruption)."
