Error 'molecules' and their implications for system safety (2003)
Unanticipated human behaviour, in the form of errors and violations, has always been a major threat to complex safety-critical systems (Perrow, 1984). Human error featured significantly in early aircraft accidents (Wilmer, 1979) and 19th century rail accidents (Rolt, 1998) and it continues to present a risk in fields such as medicine, transport and power generation (Redmill & Rajan, 1997). The threat of human error originates not only with system operators such as pilots or drivers. There is an increasing recognition that maintenance errors are a major cause of losses in a wide range of industries (Reason & Hobbs, 2003).
