Human Errors - A Taxonomy for Describing Human Malfunction in Industrial Installations

This paper describes the definition and the characteristics of human errors. Different types of human behavior are classified, and their relation to different error mechanisms are analyzed. The effect of conditioning factors related to affective, motivating aspects of the work situation as well as physiological factors are also taken into consideration.

The taxonomy for event analysis, including human malfunction, is presented. Possibilities for the prediction of human error are discussed. The need for careful studies in actual work situations is expressed. Such studies could provide a better understanding of the complexity of human error situations as well as the data needed to characterize these situations.
