Abstract:

Two types of enriched hybrid job performance aids EHJPA were developed to help inexperienced technicians troubleshoot complex electronic systems 1 the decision treefunctional flow logic diagram DTFFLD for relay circuitry and 2 the state tableextracted schematic STES 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 DTFFLD aid isolated faults over twice as fast as technicians using ordnance publications, and they achieved almost twice the gain in system understanding. The STES 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.
