Evaluation of Three Types of Technical Data for Troubleshooting: Results and Project Summary.
Abstract
This report describes a project to evaluate the effectiveness of three types of technical data for troubleshooting, fully proceduralized troubleshooting aids (FPTA), logic tree troubleshooting aids (LTTA), and technical orders (TOs). In the project, FPTAs and LTTAs, were developed for two moderately complex electronic systems, the AN/APN-147 and AN/ASN-35. The effectiveness of the technical data and the existing TOs for the systems were then evaluated by determining which provided the best support for technicians troubleshooting the systems. This was accomplished by inserting faults into the equipment and having a technician troubleshoot the system using one of the three types of data. Job performance tests were used to measure the performance of the technicians. Technicians with three levels of experience participated in the study. They were: apprentice technicians with no field experience, experienced technicians with less than six months experience on the systems, and experienced technicians with more than six months experience on the systems. The results indicate that: (1) apprentice technicians are able to troubleshoot more effectively when using FPTAs than when using LTTAs; (2) apprentice technicians troubleshoot more effectively when using FPTAs or LTTAs than when using TOs, (3) apprentice technicians using FPTAs are able to troubleshoot as effectively as experienced technicians using TOs, and (4) fewer parts are replaced unnecessarily when FPTAs or LTTAs are used than when TOs are used.
