Explanation:

Job instruction training or JIT is a form of simple on the job training where a new employee is trained step by step by a supervisor or an assigned coworker. This kind of training usually exists for jobs requiring manual skills such as factory workers. The jobs require relatively low skills and hence can be taught in a simple step by step procedure. Job instruction training can be provided on a one on one basis as well as one to many. JIT is also used to train existing workers about new technology.

The benefit of JIT is that the training is real time and based on the real workplace. Hence the trainee not only observes the trainer perform the job but also gains hands on experience in performing the job under supervision.
