The Task Taxonomy Method: A Basis for an Expert System on Human Reliability,

Abstract

A survey of human error (HE), its definition, nature of HE and the categorization of HE's, causes and prevention measures is described. Then a HE rating scale is introduced, which allows the assignment of HE probability (HEP) values measured into 10 reliability classes (RC). Based on HEP values measured for a number of human performances a Task Taxonomy Method is developed. This method allows to assign a relative weight to all task factors and to all performance shaping factors (PSF) involved in the task performance. The task taxonomy method is a tool to predict the HEP and RC of tasks allocated to man. Such a predictive tool is used for analysis, definition and design of man-machine systems. Finally rules of an Expert System are described which facilitates the application and use of the task taxonomy method.
