Abstract:

Twenty Navy technicians participated in a field evaluation of the effectiveness of enriched hybrid job performance aids EHJPAs for troubleshooting the ANAWC-10 airborne weapon control system. In a between-subjects design, each group used one of four troubleshooting formats on two troubleshooting tasks deductive information only DED, hybrid aid without any enrichment UN, an enriched hybrid TSIC, and another enriched hybrid with techincal data references SSBRC. Performance across tasks, as well as performance on a pre- and posttask using the DED format were compared. Using the TSIC format, technicians solved the two tasks 58 percent faster than did the technicians using DED. Improvement from the pre- to posttasks for the TSIC group was 65.6 percent, compared to 31.9 percent for the DED group. One hundred percent of all hybrid groups solved the posttask, compared to the 83 percent of the DED group. One hundred percent of all hybrid groups said the hybrid aids were easier to use and understand than existing technical material. In a test on system knowledge, the SSBRC group was superior when compared to the other groups. Combining the results with the user preference for the SSBRC format, it was concluded that the SSBRC was the most effective EHJPA. Author
