Human Error: In the loop
W. Ian Hamilton
BOWTIE diagrams are commonly used to investigate gaps in risk management, particularly for major accident risk control. However, these diagrams are typically biased towards technical safety, and do not fully represent human and organisational failure hazards, which are in fact the greatest component of major accident risk. This bias could be addressed by applying a simple set of three human failure cases and a strict observation of the underlying logic of the bowtie technique.
