In fact, reports stopping at human error usually fail to seek out the underlying causes of an accident 😉 Human beings are prone to making mistakes, but all too frequently organisational issues make such errors inevitable or at least more likely 😁 A few accidents can be attributed to a single cause 🙌 This is especially true for large organizations or complicated technologies. One or more of the following factors can be responsible for an incident: basic causes, root causes and immediate causes. The root cause can be used to avoid future incidents by improving process design, team safety and training. Human failings are rarely root causes – instead, a systemic approach to safety views human error as a consequence of other failures.
Human error is any erroneous or unwelcome human decision or behaviourr that could lead to safety and effectiveness reductions. Errors tend to fall into one of four categories:• Mistakes result from ignorance of the correct task or the correct way to perform it.• Mismatches occur because the tasks are beyond the physical or mental ability of the person asked to perform it.• Noncompliance (or violations) happen because someone decides not to carry out a task or not to carry it out in the way instructed or expected.• Slips and lapses result From forgetfulness, habitual, fatigue, or other psychological reasons.
Because human errors often arise from complex events, it is difficult to give a satisfying definition. However, Reason has defined “human error” in the following way: “Error will be taken as a generic term to encompass all those occasions in which a planned sequence of mental or physical activities fails to achieve its intended outcome, and when these failures cannot be attributed to the intervention of some chance agency.” It has also been stated that to err is human (I.e. It is normal to make errors. While human error can’t be completely eliminated, the majority of common mistakes can be avoided if they are detected.

Actions can either be unintentional or intentional. The desired outcome can be reached if a plan is sufficient and an intentional action conforms to it. Unintentional actions that are not consistent with the plan will result in a poor plan. The same applies to a plan that is not adequate, but an intentional act follows it. This will result in the opposite outcome. The figure below shows these error points and is explained in detail in the following example.
