This paper describes a prototype software tool that offers support to the human factors specialist using hierarchical task analysis (HTA). The tool provides a direct manipulation diagram editor for HTA and provides high-quality output of analyses, in both graphic and automatically generated tabular form. The tool is implemented in Smalltalk-80 and currently runs on Macintosh computers.
