There are three types of rule-based mistakes: incorrect application of a good rule correct application of a bad rule failure to apply a good rule.  Some rules that are appropriate for http://renderq.net/human-error/human-factor-error.php

Types Of Human Error

There are three main types of violations pertaining to human error: routine, situational, and exceptional. http://patientsafetyed.duhs.duke.edu/module_e/types_errors.html If a plan is adequate, and the intentional action follows that plan, then the desired outcome will be achieved.
