Dekker on Resilience Engineering

This is a short video by Sidney Dekker talking about Resilience Engineering. He claims it is a completely new way of understanding accidents, which moves on from more traditional approaches which have looked at 'human error'. He makes the point that traditional approaches to human error assume that systems are safe and it is only error prone humans that errode safety. The new perspective sees variance and disturbances in systems as 'normal', that these systems are imperfect because of multiple competing goals, and it is the presence of people that adapt and hold these systems together, i.e. the systems actually work because of people not despite them. Safety is seen as the presence of resilience rather than the absence of error.
