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] Human error and performance are two human error prevention 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 biases. Such heuristics and biases are strategies that are useful and often corr

This is usually used to differentiate the source of errors from other causes such as measurement error, random variation, machine failure, lack of calibration, improper design, etc. I believe it was Einstein who said that it is difficult to make things fool proof because fools are so damn ingenious. Machines and automated system are very good at doing the same thing over and over again (good repeatability and reproducibility). Humans get easily bored doing repetitive tasks so frequently, machines and automated systems are used to control repetitive processes. Human nature is such that, when people are given control over a process, they are likely to experiment with the process, turning knobs and adjusting things to see what happens. Sometimes this leads to significant improvements in a process but it often leads to increasing the variation in processes. For example, the airline industry and the military have done a great dea

Human errors can be described as bumbling mistakes made during an experiment that can invalidate your data and conclusions. Scientists recognize that experimental findings may be imprecise due to variables difficult to control, such as changes in room temperature, slight miscalibrations in lab instruments, or a flawed research design. However, scientists and college professors have little tolerance for human errors occurring due to carelessness or sloppy technique. If you human error know you really messed up, redo the experiment. Failure to Follow Directions Before leaping into a laboratory activity, carefully read the instructions in the lab manual thinking about the purpose of the experiment and possible results. If you don’t understand a step, consult with your lab partner or instructor before proceeding. Perform each step of the experiment in the correct order to the best of your ability. Don’t attempt shortcuts in of human error the procedure to save time. Conducting an experiment is similar to following a recipe in the kitchen but far more exacting. Even slight deviations can change your results in dramatic ways. Mishaps in Measuring Spilling chemicals when measuring, using the wrong amount of solution, or forgetting to add a chemical compound are mistakes commonly made by students in introductory science labs. Measurement errors can result in flawed data, faulty conclusions and a low grade on your lab report. Worse still, you may cause a dangerous chemical reaction. Ask your lab instructor for guidance if you know your measurements are way off from the instructions; sometimes the experiment or your calculations can be adjusted to avoid starting over. It is better to be safe than to risk injury to yourself and others. Contamination Failing to maintain sterile conditions can cause contamination and produce unwanted results in your experiment. For example, coughing or breathing into the petri dish when inoculating nutrient agar with a certain type of bacteria can introduce other bacterial strains that may also grow on your culture. Mold spores and dust can harm your experiment if you forget to wipe down your work area with alcohol. Touching the tip of a pipette before using it to transfer liquids dur
