人为错误可以简单地描述为人类犯下的错误。但它比这复杂一点。人们犯错误。但为什么他们犯错误很重要。考虑到这一点，人为错误是指一个人犯错误，因为那个人犯了错误。而不是被设计的其他因素混淆或影响。它也称为操作员错误。还有一集我爱露西的老插曲，露西在装配线拳击糖果工作。这条线路移动得太快，以至于她无法跟上疯狂的连环漫画。系统故障不是机械故障，而是人为错误。人为错误是人体工程学中的一个重要概念，但它主要在上下文中提到。这是一个可能的答案：“导致事故的原因是什么？”或者“它是怎么破坏的？”这并不意味着花瓶因人为错误而破裂。但是，当您从一台设备或系统评估事故时，原因可能是人为错误。它也可能是不正确的安装或制造缺陷或一系列其他可能性。人为错误通常在事故或事故调查期间被调用，例如车祸，房屋火灾或导致召回的消费品问题。通常，它与负面事件有关。在工业运营中，可能会出现一种意外后果。这可能不一定是坏的，只是原因不明。调查可能会得出结论，设备或系统设计很好但是人体组件搞砸了。象牙肥皂的传说是由于人为错误导致的积极意外后果的一个例子。早在1800年代，Proctor and Gamble就制造了他们的新型白色肥皂，希望能够在精致的肥皂市场上竞争。有一天，一名线路工人在他去吃午餐时离开了肥皂搅拌机。当他从午餐回来时，肥皂是额外的泡沫，加入了比正常更多的空气。他们将混合物送到生产线上并将其变成肥皂块。不久，宝洁公司被淹没了浮动肥皂的请求。他们调查，发现人为错误，并将其纳入他们的产品象牙肥皂，这种肥皂在一个多世纪后仍然畅销。 （注意 – 宝洁公司最近的研究表明肥皂实际上是由他们的一位化学家发明的，但传说中的例子仍然说明了人为错误点）从设计角度来看，工程师或设计师生产一件设备或系统意图以某种方式运作。当它不起作用（它破裂，着火，弄乱它的输出或遭受其他一些不幸事故）时，他们试图找到根本原因。
Human error can simply be described as an error made by a human. But it gets a little more complicated than that. People make mistakes. But why they make mistakes is important. With that in mind, human error is when a person makes a mistake because that person made a mistake. As opposed to being confused or influenced by other factors of the design. It is also known as Operator Error. There’s an old episode of I Love Lucy where Lucy gets a job working on an assembly line boxing candies. The line is moving too fast for her to keep up and madcap comic romps ensure. The breakdown in the system was not mechanical but human error. Human error is an important concept in ergonomics but it is mainly referred to in context. It is a possible answer to the questions: “What caused the accident?” or “How did it break?” That doesn’t mean that the vase broke because of human error. But when you are evaluating a mishap from a piece of equipment or a system then the cause may be human error. It may also be incorrect installation or a manufacturing defect or a slew of other possibilities. Human error is typically called into being during an accident or mishap investigation such as a car crash, house fire or a problem with a consumer product leading to a recall. Usually, it is associated with a negative happening. In industrial operations, something called an unintended consequence may occur. This may not necessarily be bad, just unexplained. And investigation may conclude that the equipment or system design is fine but the human component messed up. The legend of Ivory soap is an example of positive unintended consequences due to human error. Back in the late 1800’s Proctor and Gamble were manufacturing their new White Soap with hope to compete in the fine soap market. One day a line worker left the soap mixing machine on while he went to lunch. When he got back from lunch the soap was extra frothy having incorporated more air than normal into it. They sent the mixture down the line and turned it into bars of soap. Soon Proctor and Gamble were inundated with requests for the soap that floats. They investigated, found the human error, and incorporated it into their product Ivory soap which is still selling well over a century later. (Note-recent research by Proctor and Gamble suggests that the soap was actually invented by one of their chemists but the legendary example still illustrates the human error point) From a design perspective, the engineer or designer produces a piece of equipment or a system with intentions to function in a certain way. When it doesn’t function that way (it breaks, catches on fire, messes up its output or is befallen of some other mishap) they try to find the root cause.
