Proposed Screening Methods
The truly outstanding troubleshooter approaches the unique. The exact quali-
ties that set him apart from one with less expertise are not easy to define.
Testing designed to determine knowledge of fundamental electronics and
oriented toward specific job requirements, educational background, and experi-
ences was found to correlate with performance to a usable degree. Testing
proved to be the most effective of the three methods of evaluation, but all
should be considered. Present bargaining-unit agreements and company
procedures place the same restriction on testing.
The following method was chosen to determine adequate troubleshooter skills.
e Give a written test to determine adequate knowledge of electronic funda-
mentals and adequate aptitude.
" Give a 3-week on-the-job evaluation and training period under the direc-
tion and observation of a process engineer before promoting or hiring
an employee into the troubleshooting category.
" Establish an educational minimum of high school graduate anda graduate
of electronic trade school.
Production Improvements Resulting From Skill Level Definitions
As a result of the evaluation conducted in the development effort, production
now conducts training or familiarization schools for new programs, and
also maintains a training school for production troubleshooters to upgrade
their overall technical ability.
Developing Troubleshooting Manuals
Preliminary Evaluation. The efficient translation of engineering information
and product definition to the troubleshooter level is a critical dimension in
any faultfinding system. In addition to normal unit definition, the trouble-
shooter needs knowledge in such areas as theory of tester and circuit functions;
operating procedures; typical dc voltages; ac waveform references; general
troubleshooting instructions, including failure symptons and likely cause;
and visual aids that will quickly locate components physically and identify
them according to schematic designations. The design criteria for the text
of the troubleshooting manual was developed by an on-the-job study, with
the objective of finding the needs of production troubleshooters in the areas
mentioned in the above paragraph.
A study was conducted to determine these needs, and resulting design criteria
were defined as follows.
Here’s what’s next.
