Job Instruction Manual - Training Within Industry Service

1. THE LONG OPERATION
Tltree Special Instruction Probiems
- How to use the 4-step method on a working operation that takes
perhaps 3 hours or 3 days.
- This is where correct instruction is MOST important. This
is a situation where the learner and the instructor become
most "confused" and "lost. "
- The answer is to "break up" the long operation into small "doses, I'
then put over one dose at a time.
a. Examples in the meeting room.
- Frequently jobs selected are: How to read the Micrometer; or
Slide rule; or Vernier. When selected they should be so
handled by the Trainer to illustrate the need for small unit
breakdowns. These jobs should be put over by small units.
- Example-Micrometer
one unit-with Steps I, 11, and 111; parts and care of the
instrument.
one unit-with Steps I1 and 111; the sca,les and their rela-
tion to each other.
one unit-with Steps I1 andIII; making simple measurements.
one unit-with Steps 11, 111, and IV; difficult measure-
ments, i. e. , those requiring reading in fractions
of thousandths.
b. Examples on the job.
(1) Installing bulkhead in ship.
This job requires about 2 hours, and must be completed
without interruption because of the gantry cranes that
are tied up. There is no opportunity to stop and instruct
a man in each unit separately. Yet there are about six
highly important and reason~bly technical units in the job
that must be mastered with great accuracy.
- The answer is for the gang boss not to try to explain the
whole installation.
