Troubleshooting Performance Using Paper and Electronic Documentation
Abstract
Four troubleshooting tasks were administered to 36 technicians, 12 each from the Air Force, Navy, and Marine Corps. The tasks consisted of identifying a fault introduced into a circuit relay or discrete component on a printed circuit card used in the RT-728A/APX-64(V) radio receiver transmitter. Two tasks were performed using conventional manuals and two using information presented on a GRID Compass II computer. Significant differences were found with regard to time to identify faulted card, total problem solution time, and number of false item replacements, all of which were less for electronic than for conventional information delivery. Significant differences were also found with regard to number of test points checked, total number of tests performed, and number of problems solved, all of which were greater for electronic than for conventional information delivery. Thus, with electronic information delivery, technicians performed electronic information delivery were also consistently favorable. The only major criticism of the computer concerned the inadequacy of screen size for displaying schematics.
