✦ Synopsis

A model of the interface design process is proposed that uses two interdependent levels of cognitive analysis. (a) study of the criterion task through the analysis of expert/novice differences, and (b) evaluation of the working user interface design through the application of practical in terrace analysis methodology (the GOMS model) This dual analysis is reviewed m the context of HYDRIVE, an intelligent tutonng system that has been designed to facilitate the development of aircraft hydrauhcs systems troubleshooting skdls. Inltml cognitive task analyses identified critical troubleshooting skills and procedures However, even with an initial cogmtlve task analysis, the GOMS analysis resulted in significant and beneficial design changes
