errors in carrying out an intended method for reaching an objective (Sternberg 1996). As Norman (1986: p. 414) explains: examples of human error in experiments "The division occurs at the level of the intention: A Person establishes an intention to act. If the intention is not appropriate, this is a mistake. If the action is not what human error synonym was intended, this is a slip."
For example, a mistake would be to buy a Microsoft Excel licence because you want to store data that should be made accesible to web clients through SQL-queries, as Microsoft Excel is not designed for that purpose. In other words, you choose a wrong method for achieving your objective. However, if you installed a Postgresql Server forData Driven Error
the same reason but in your haste forgot to give the programme privileges to go through your firewall, that would be a slip. You chose the right method of achieving your objective, but you made an error in carrying out the method. Both Reason (1990) and Norman (1988) have described several kinds of slips (see 'related terms' below). According to Sternberg (1996), "slips are most likely to occur (a) when we must deviate from a routine, and automatic processes inappropriately override intentional, controlled processes; or (b) when automatic processes are interrupted - usually as a result of external events or data, but sometimes as a result of internal events, such as highly distracting thoughts." See the glossary term Capture Error for an example. Overall, it should be noted that "The designer shouldn't think of a simple dichotomy between errors and correct behavior: rather, the entire interaction should be treated as a cooperative endeavor between person and machine, one in which misconceptions can arise on either side."

was "not intended by 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 https://www.interaction-design.org/literature/book/the-glossary-of-human-computer-interaction/human-error-slips-and-mistakes 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, a mere failure is not an error if there had been no plan to accomplish something in particular.[1] Performance[edit] https://en.wikipedia.org/wiki/Human_error 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 communication versus organizational. Sources[edit] The cognitive study of human error is a very active research field, including work related to limits of memory and attention and also to decision making strategies such as the availability heuristic and other cognitive bi

By anticipating where the errors are likely to occur in the human-computer interaction and workflow, we hope to reduce number of errors and minimize the effects of inevitable errors.IntroductionAn error caused by an individual can be grouped into a “slip” or a “mistake” [1][3][4]. A mistake is an error as a result of an intended action but incorrect plan, and slip is an error as a result of a correct plan but a result of an unintended action [1][5]. Work by Rasmussen, Reason, Norman, and others on cognitive theories on errors was applied in the design of a tracking system. The purpose of the software is to keep track of samples throughout the life of collected samples at General Clinical Research Center (GCRC) laboratory.DesignTo gain an understanding of the process of collection and analysis of samples in a GCRC laboratory, a user who is familiar with GCRC laboratory p
