“This module attempts to cover all aspects of the process of designing, implementing, and evaluating user interfaces. Inputs to the process include the results of requirements analysis for the system, although this module has some coverage of task analysis, requirements analysis of the human components of systems. Outputs of the process include systems of software and user documentation, however more detailed coverage of documentation should be sought elsewhere, and the module contains little coverage of field-testing of usability over the long-term maintenance of systems.” Note: From November 1989.
