Enhancing the usability of a task analysis method: a notation and environment for requirements specification

Article Abstract:

The notation and computer-based tool for the Sub-Goal Template task-analytic approach to specifying information requirements were described. Two experiments were conducted in which two notations for redescribing sequences that involve making a choice between task alternatives were compared. Results showed that the computer environment was found to be easier to use and led to more accurate plan redescription. Ergonomic design in developing notations and tools to support task analysis methods were found to be necessary.

Article Abstract:

A study examined whether people can judge the usability of display-control mappings. The results show that choices were correct when usability is defined by an unambiguous spatial relationship and choices were less accurate for items, which did not rely on spatial congruence.
