Enriched Hybrid Job Performance Aid Development
Abstract
Two types of enriched hybrid job performance aids (EHJPA) were developed to help inexperienced technicians troubleshoot complex electronic systems: (1) the decision tree/functional flow logic diagram (DT/FFLD) for relay circuitry and (2) the state table/extracted schematic (ST/ES) for digital solid state circuitry. These hybrid aids contain more functional information than fully proceduralized aids but are easier to use than a technical manual. Technicians using the DT/FFLD aid isolated faults over twice as fast as technicians using ordnance publications, and they achieved almost twice the gain in system understanding. The ST/ES aid also improved performance, as evidenced by a comparison of troubleshooting protocols. Both aids provide succinct functional descriptions that tie theory of system operation to functional flow information needs.
