Human error

The study of absent-mindedness in everyday life provides ample documentation and categorization of such aspects of behavior.

When errors occur in hazardous environments, there is a greater potential for things to go wrong. When we recognise that the current situation does not fit with any rule stored, we shift to knowledge-based behaviour. While human error is firmly entrenched in the classical approaches to accident investigation and risk assessment, it has no role in newer approaches such as resilience engineering.

This is roughly—but not exactly—what we call consciousness. Countermeasures are based on the assumption that although we cannot change the human condition, we can change the conditions under which humans work.

Including correction tells a different story: Each has its model of error causation, and each model gives rise to different philosophies of error management. This adjustment takes place without burdening our limited attentional system in most cases.

Further, individual decision-making is primarily influenced by the consequences the individual expects to receive as a result of their behaviour, which can influence their attitude towards that behaviour.

Latent errorsor Latent human error result in hidden organization-related weaknesses or equipment flaws that lie dormant.

This error type is categorised into slips of action and lapses of memory. Errors result from a variety of influences, but the underlying mental processes that lead to error are consistent, allowing for the development of a human error typology.

They anticipate the worst and equip themselves to deal with it at all levels of the organization. For example, in a particular office building it is against the rules for personnel to use the fire escape stairwell to move between floors, but it is common practice for people to do so anyway.

A broad spectrum of research indicates that the automatic subsystem uses schemata [Bartlett, ; Neisser, ]—organized collections of information and response patterns.

Usually this can happen only when the holes in many layers momentarily line up to permit a trajectory of accident opportunity—bringing hazards into damaging contact with victims figure.

In addition, once the adjustment begins, it takes on a life of its own, sometimes going in unforeseen directions. The task has probably been performed correctly many times before.

Failures in planning are referred to as mistakes, which are categorised as rule-based mistakes and knowledge-based mistakes.

When it doesn't function that way (it breaks, catches on fire, messes up its output or is befallen of some other mishap) they try to find the root cause.

Human reliability

Slips and lapses can be minimised and mitigated through workplace design, effective fatigue management, use of checklists, independent checking of completed work, discouraging interruptions, reducing external distractions, and active supervision.

This book is really in depth and gives a lot of good infomation on why people make mistakes. If you are looking for additional information on human error, try this book.4/4(19).
