Further, individual decision-making is primarily influenced by the consequences the individual expects to receive as a result of their behaviour, which can influence their attitude towards that behaviour. From a human error perspective, there are three potential alternative scenarios that he may experience when executing his plan:   Each of the failure types can be further broken down into categories and subcategories.

Essential HSE generic industry guidance on human factors - a simple introduction. Errors can be broadly distinguished in two categories: Category 1 - A person intends to carry out an action, the action is appropriate, carries it out incorrectly, and the desired goal is not achieved. - An execution failure has occurred. Plans can be adequate or inadequate, and actions (behaviour) can be intentional or unintentional. Likewise, it is not difficult to imagine that when under stress during in-flight emergencies, critical steps in emergency procedures can be missed.

Human error. When confronted with an unexpected or inappropriate situation, personnel may believe that the normal rule is no longer safe, or that it will not achieve the desired outcome, and so they decide to violate that rule. If a plan is adequate, and the intentional action follows that plan, then the desired outcome will be achieved.

If a plan is adequate, but an unintentional action does not follow the plan, then the desired outcome will not be achieved.
