task or system outside its acceptable limits".[1] In short, it is a deviation from intention, expectation or desirability.[1] Logically, human actions can fail to achieve their goal in two different ways: the actions can go as planned, but the plan can be inadequate (leading to mistakes); or, the plan can be satisfactory, but the performance can be deficient (leading to slips and lapses).[2][3] However, human error in experiments a mere failure is not an error if there had been no plan to accomplish something in particular.[1] Performance[edit] Human error and performance are two sides of the same coin: "human error" mechanisms are the same as "human performance" mechanisms; performance later categorized as 'error' is done so in hindsight:[4][5] therefore actions later termed "human error" are actually part of the ordinary spectrum of human behaviour. The study of absent-mindedness in everyday life provides ample documentation and categorization of such aspects of behavior. 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.[6] Categories[edit] There are many ways to categorize human error.[7][8] exogenous versus endogenous (i.e., originating outside versus inside the individual)[9] situation assessment versus response planning[10] and related distinctions in errors in problem detection (also see signal detection theory) errors in problem diagnosis (also see problem solving) errors in action planning and execution[11] (for example: slips or errors of execution versus mistakes or errors of intention[12][13]) By level of analysis; for example, perceptual (e.g., optical illusions) versus cognitive versus c

This does not mean that human https://en.wikipedia.org/wiki/Human_error error cannot be investigated by scientific principles. In fact, today, there is considerable interest in researching human error [1]. The aim of this article is to describe human errors and their relationships with occupational accidents. Definition of human error The aim of this chapter is to define what is considered as “human error”. Another, the aim is to compare the traditional and modern views of human error. It is very difficult http://oshwiki.eu/wiki/Human_error to provide a satisfactory definition of human errors [2] as they are often a result of a complicated sequence of events and therefore an elusive phenomenon to analyse. However, Reason [3] has defined “human error” in the following way: "Error will be taken as a generic term to encompass all those occasions in which a planned sequence of mental or physical activities fails to achieve its intended outcome, and when these failures cannot be attributed to the intervention of some chance agency." On the other hand, it has been said that to err (i.e. to make mistakes) is human. Human error is an element that cannot be totally eliminated, but if the typical errors are identified, most of them can also be prevented. According to the traditional viewpoint, human error is a cause of failure and accident. According to a new philosophical approach, human error is a symptom of failure, which reflects the deeper problems existing in a system. Examining human error provides information to delve beneath the simplistic label of 'human error'. Human error is an attribution after the fact, and it is systematically related to people, tools, tasks, and operating environment[4], [5]. Although there in no unanimous definition of human error, the general thinking has changed from attribu

They are categorized according to the cognitive processes involved human error towards the goal of the action and according to whether they are related to planning or execution of the activity. Description Actions by human operators can fail to achieve their goal in two different ways: The actions can go as planned, but the plan can be inadequate, or the plan can be satisfactory, of human error but the performance can still be deficient (Hollnagel, 1993). Errors can be broadly distinguished in two categories: Category 1 - A person intends to carry out an action, the action is appropriate, carries it out incorrectly, and the desired goal is not achieved. - An execution failure has occurred. Execution errors are called Slips and Lapses. They result from failures in the execution and/or storage stage of an action sequence. Slips relate to observable actions and are commonly associated with attentional or perceptual failures. Lapses are more internal events and generally involve failures of memory. Category 2 - A person intends to carry out an action, does so correctly, the action is inappropriate, and the desired goal is not achieved - A planning failure has occurred. Planning failures are Mistakes. “Mistakes may be defined as deficiencies or failures in the judgmental and/or inferential processes involved in the selection of an objective or in the specification of the mean
