the actor; not desired by a set of rules or an external observer; or that led the 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 human error types 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, 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 disti

Human performance can be affected by many factors such as age, state of mind, human error in experiments physical health, attitude, emotions, propensity for certain common mistakes, errors human error synonym and cognitive biases, etc. Human reliability is very important due to the contributions of humans to human error percentage the resilience of systems and to possible adverse consequences of human errors or oversights, especially when the human is a crucial part of the large socio-technical https://en.wikipedia.org/wiki/Human_error systems as is common today. User-centered design and error-tolerant design are just two of many terms used to describe efforts to make technology better suited to operation by humans.

PRA-based techniques[edit] One method for analyzing human reliability is a straightforward extension of probabilistic risk assessment (PRA): in the same way that equipment can fail in a power plant, so can a human operator commit errors. In both cases, an analysis (functional decomposition for equipment and task analysis for humans) would articulate a level of detail for which failure or error probabilities can be assigned. This basic idea is behind the Technique for Human Error Rate Prediction (THERP).[3] THERP is intended to generate human error probabilities that would be incorporated into a PRA. The Accident Seque

A causal factor is human error anything that yields an occurrence resulting in an undesired effect or anything that exacerbates the level of severity of the undesired effect.Why is it important to understand human error causal factors? The answer is twofold.First, a good design (either the design of a process or hardware item) is created, in large part, with an understanding of:Any potential undesired effects in operating or maintaining the process or in manufacturing, transporting, of human error storing or using the hardware itemThe human errors and their causal factors that can activate these undesired effects.With this understanding, the intent is to design such as to eliminate the potential for the undesired effects, or when that can’t be done, to establish appropriate barriers for the:Prevention of any error that could activate the undesired effectTimely detection of the errorMitigation of the undesired effect.Of course, the resources applied to any such barriers are appropriate to the level of significance of the undesired effect.Second, without an understanding of human error causal factors, there is a greater potential for root cause analyses to be truncated at the point at which only the things that need correction are identified, rather than analyzing further to the point of identifying the behaviors that need correction as well. For example, a correction may be made to a specific integrated maintenance and inspection plan (a thing) or corrections may be made to a set of such plans (things) that have the same or similar offending characteristics, but such a correction or corrections will not prevent newly prepared plans from having the same or similar offending characteristics. Improvement in new plans can come about only with improvement in the behavior of the planne
