Community—The resilience engineer

Erik Hollnagel, the originator of the Safety I/Safety II concept, is pictured with consultant Hillary Bennett at Eden Park, where Hollnagel gave a seminar in August. Safety I – measuring what goes wrong and trying to prevent it happening again – is OK so far as it goes, he said, but it doesn’t go far enough. “Why things work, not why they fail, that is the question!” Hollnagel praised human adaptability to circumstances, which he said is the only reason anything works at all. People adjust to slight changes in circumstances and make things work, which is why his Safety II concept emerged from his earlier work in resilience engineering. “Performance variability is the reason why everyday work is safe and effective. Constraining performance variability to remove failures will also remove successful everyday work.”
