Definition of Troubleshooter Skill Level. The precise definition of an ideal
skill level for the production troubleshooter seems somewhat elusive when
such ramifications as the following are considered: the wide range of com-
plexity found in diagnostic problems; the near-intangible factors that
contribute to the definition of the troubleshooter's ability; the intricate
relationship of troubleshooting skill level, translation of engineering infor-
mation to the troubleshooter, and the degree of sophistication of diagnostic
equipment. Review of each of these parameters indicated that limitations
exist on the minimum acceptable skill level for the troubleshooter, but the
job complexity review shows that, with adequate engineering support and
proper equipment, most diagnostic work can be performed with less than
engineering skill. However, the technical requirements are high enough
to demand rigid screening of technicians. Significant economic advantages
are realized by a reduction of skill level from engineer to technician.
To assure accurate and efficient diagnosis of problems with the complexities
found in telemetry assemblies, the troubleshooting group must have
the following capabilities:
. Technical capabilities that enable the troubleshooter to isolate 95 percent
or more of assembly errors or component faults on the first diagnostic
attempt, assuming a physical configuration that permits access to suffi-
cient circuit nodes to make the analysis;
" Sufficient technical knowledge to quickly interpret technical information
contained in engineering support material which is presented at a level
that assumes strong technical background;
" Sufficient understanding of all circuit functions and design iditen]t to enable
the troubleshooter to recognize subtle, marginal; or abnormal parameter
deviations and to evaluate stress effects on associated circuits caused by
component or assembly failures; and
" Technical skill sufficient to support or correct troubleshooting decisions,
to evaluate individual and group performances, to act as liaison between
engineering and production on problems that involve design, to act as
a buffer between the troubleshooter and other staff personnel, and to
face the general responsibilities of upgrading and maintaining the techni-
cal capabilities of the group.
Evaluating Troubleshooter Performance. Study results showed that operator
performance, in many instances, did not correlate with some of the standards
used to set qualifications such as technical schooling, experience, and back-
