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 communication ver

Mistakes are errors in choosing an objective or specifying rule based error a method of achieving it whereas slips are errors in carrying out an intended method for reaching

an objective (Sternberg 1996). As Norman (1986: p. 414) explains: "The division occurs at the level of the intention: A Person establishes an intention to act. If the https://en.wikipedia.org/wiki/Human_error intention is not appropriate, this is a mistake. If the action is not what 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 https://www.interaction-design.org/literature/book/the-glossary-of-human-computer-interaction/human-error-slips-and-mistakes that purpose. In other words, you choose a wrong method for achieving your objective. However, if you installed a Postgresql Server for 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 interabe down. Please try the request again.
