requirements and ensure that sufficient personnel are trained for each task.
This requires that he have adequate knowledge of the technical requirements
of the tasks and the problems of training personnel to perform them. The
technical requirements involve learning to operate specially-designed diag-
nostic equipment, and learning to use program-oriented troubleshooting
procedures, routing procedures, and other applicable control documents.
Two areas that involve appraisal of personnel fall into the duties of the
" The appraisal of individual troubleshooters doing the diagnostic work;
" The appraisal of the capabilities of applicants for that classification.
Appraisal of the troubleshooter doing the work is necessary to determine
individual performance, to aid in upgrading personnel, and to assign causes
to discrepant troubleshooting results such as anonymous inspection rejections
and failures that are verified and cannot be repeated.
The theoretical introduction and on-the-job evaluations of incoming appli-
cants for the job classification may fall in the area of engineering support.
Evaluating the applicant's knowledge of standard diagnostic equipment and
familiarization training in this area are the technical duties of the pro-
duction supervisor working on the factory floor.
The production supervisor should have sufficient technical skill to assist in
the troubleshooting effort when the diagnostic problem is particularly diffi-
cult and time consuming. He should have sufficient technical knowledge
of the product to recognize an engineering problem and to act as liaison
between the troubleshooter and the engineering department.
Reliability Aspects of Operator Skill Level. The high reliability require-
ments of telemetry products demand accurate localization of production
electronic failures. This, in turn, limits the minimum skill level of trouble-
shooting personnel. Many of the component and assembly faults observed
during the study subjected associated circuitry to abnormal stress conditions.
The identification of the circuitry and the judgments concerning corrective
action is part of the diagnostic troubleshooting problem. Several potential
engineering problems were discovered during troubleshooting, and engineering
was alerted. Although some of the reports proved invalid, it was evident
that highly skilled troubleshooting personnel with thorough knowledge of circuit
function and design intent can be an effective safeguard against possible
hidden or marginal conditions.
