Job Instruction Training (JIT)
During World War II (December 7, 1941 and lasting for 5 years), the need for a method of fast and efficient training arose. Training Within Industry, an advisory service formed by the National Defense Advisory Commission, developed the systematic on-the-job training method called JIT (Job Instruction Training). Its goal was to train supervisors in defense plants in the skills of instructing their workers as fast as possible. At first the train-the-trainer classes were three days long, but soon grew to a 45-hour program.
Other J programs soon followed:
- JRT - Job Relations Training
- JMT - Jobs Methods Training
- JST - Job Safety Training
- JiTT - Just in Time Training
