Abstract
Task analysis is one of the most useful tools for investigating human tasks and together with associated analysis techniques it provides considerable versatility, that enables analysts to investigate a wide range of issues on both new and existing systems. However, software tools for task analysis generally do not currently provide the flexibility or range of applications, to fully utilize this versatility.
Therefore, in order to define the user requirements for an analyst using a task analysis package, a task analysis was undertaken of the task analysis process. This produced an extensive set of different user requirements, both at a generic level and at the level of specific analysis techniques. Some of the more significant of these findings are summarized. It was also noted that there is room for some standardization in the way that some features of task analysis data are presented, in order to assist the readers of a task analysis to understand the data presentation of task analysis data.
