actions that exceeds some limit of satisfactoriness, any act or inaction that
exceeds the tolerances written by the system thereupon the human interacts, the failure to
understand associate supposed outcome on the manner facet the influence of
random incidence, a necessary outcome to permit humans to explore and perceive
systems operators social information of responsibility and values.
These definitions convey the many-sided nature of human error. chiefly,
however, they recommend the 2 complementary proposals that human operators unit
of measurement organic mechanisms with failure rates and tolerances analogous
to hardware/software components of a system, that human error is additionally
associate degree uncomplimentary term for ancient human behavior in usually
unkind environments, wherever solely the highest result determines if this
behavior is injurious. These three views also are mirrored at intervals the
three major approaches developed to handle human error in accident and incident
