All training methods can be grouped into two categories :- a] Training methods for operatives and b] Training methods for managers a] Training Methods for Operatives :-
Under these methods the new employee is assigned to a specific job at a machine or workshop or laboratory. He is instructed by an experienced employee or by a special supervisor who explains to him the method of handling tools, operating the machines etc.
Vestibule Training :- This method involves the creation of a separate training centre within the plant itself for the purpose of providing training to the new employees. An experienced instructor is put in-charge of this training. Machines and tools are also managed in the training centre, so as to create working conditions similar to those in the workshop.
Advantage :- No interference with regular production.
Disadvantage - Costly, adds nothing to productions during training period.
Apprenticeship Training :-This method of training is meant to give the trainee sufficient knowledge and skill in those trades and crafts in which a long period of training is required for gaining complete proficiency.
Generally, the trainees work as apprentices under the direct supervision of experts for long periods of say, two to seven years. This programme consists of providing actual work experience in the actual job as well as imparting theoretical knowledge through class room lectures which may be arranged either in the plant or in the institution attached to the concern. This method of training enables the trainees to become all-round craftsmen. But this method is very expensive and also there is no guarantee that a trained worker will continue to work in the same concern after the training is completed.
Internship Training :- This method of training is generally provided to the skilled and technical personnel. The object of this type of training is to bring about a balance between theoretical and practical knowledge,
