However in the workplace, the consequences of such human failure can be severe. Analysis of accidents and incidents shows that human failure contributes to almost all accidents and exposures to substances hazardous to health. Many major accidents e.g. Texas City, Piper Alpha, Chernobyl, were initiated by human failure. In order to avoid accidents and ill-health, companies need to manage human failure as robustly as the technical and engineering measures they use for that purpose. The challenge is to develop error tolerant systems and to prevent errors from initiating; to manage human error proactively it should be addressed

error, although in some cases we have made the error due to being misled by information we had received. Our reaction to human error percentage human error can range from laughter to fear although this really depends upon the consequences of the error.The first step is to accept that we all make mistakes or forget things regardless of our experience or technical http://www.hse.gov.uk/humanfactors/topics/humanfail.htm ability, at the end of the day we are all only human.Human error descriptions have three distinct components:Causes of human error: One perspective is internal mechanisms for error that occur within the person making the error, but what are the triggers for these internal error mechanisms? Another perspective is that external triggers (environmental, performance shaping factors) impact upon the person committing the error and which induce those error mechanisms.Forms of human error: The form http://ergonomicsblog.uk/human-error/ of the error can be described as the interaction of the error with the task performed. There are many descriptions of the forms of human error, which are not exclusive, the most common are as follows:Error TypeDescriptionError of omission (lapses)Not done, Forgotten, Sacrificed.Error of commission (slips)Not done adequately, Not fast enough, Part finished, Too little, Too much, Too soon, Too late.Extraneous error (mistakes)Wrong act done, One additional action.SubstitutionCompletely different taskViolationsDeliberate acts or deviations.For more information on human error types see the UK HSE website or click here to read more.Consequences of human error: The consequences of human error are not connected with human performance, but are instead linked to the task, environment and the interaction with the technology.Human Error in HealthcareObviously medical staff do not want to hurt patients, yet we often hear blame being applied to the human. Competence doesn’t always safeguard against errors and omissions that result in harm. There are often times when an error will still result in an acceptable outcome (merely breaching layers of defence) or a near miss, or should the worst occur an accident, with varying degrees of consequence. Sometimes when errors occur, people typically blame the human instead of what might be the real culprit, the interface.In health care, the goal of human factors is to improve human performance with
accidents, and commercial aircraft disasters. Initially, error research in these specialties evolved in parallel, with only limited cross-fertilization. In recent years, http://panko.shidler.hawaii.edu/HumanErr/Theory.htm however, the specialties have been growing closer and have been converging toward a common set of findings and at least partial theories. Recently, Reason [1990] has summarized a great deal of research on human error. An edited volume by Baars [1992a] has summarized research on speech errors, which is arguably the most mature human error specialty. The Emerging Model human error Perhaps the most important aspect of convergence in human error research has been movement toward at least a partial model of human cognition consistent with a broad spectrum of human error research. Figure 1, which illustrates the basic elements of this emerging model, is drawn from Reason’s [1990] Generic Error-Modelling System (GEMS) and Baars’ [1992b] Global Workspace (GW) Theory. Reason human error in [1990, 46] cites several related theories. Figure 1: Emerging Model of Cognition Before discussing this emerging model of cognition, it is important to understand that this is not a model for errors alone. It is a model for overall cognition. Researchers now agree that both correct performance and errors follow from the same underlying cognitive processes [Reason, 1990, p. 36]. Human cognition uses processes that allow us to be amazingly fast [Reason, 1990], to respond flexibly to new situations [Reason, 1990], and to juggle several tasks at once [Flower & Hayes, 1980]. Unfortunately, these processes inevitably produce occasional errors. As Reason [1990, p. 36] expressed the situation, "an adequate theory of human action must account not only for correct performance, but also for the more predictable varieties of human error. Systematic error forms and correct performance are seen as two sides of the same theoretical coin." In most situations, the occasional errors produced by human cognitive processes rarely cause serious problems. In large spreadsheet models with thousands of cells, however, even a minuscule error rat
