On the Job Training methods include coaching, mentoring, job rotation, job instructional technique (JIT), apprenticeship, and understudying. These methods have trainees learn by observing managers and peers perform jobs, with the goal of imitating their behaviors without disrupting regular work. Trainees learn on actual machines and follow approved standards while earning. Coaching and mentoring are one-on-one and help transfer theory to practice, but can perpetuate existing practices. Job rotation exposes employees to related jobs to prevent boredom and develop relationships. JIT provides step-by-step instruction to ensure learning. Apprenticeship and understudying involve long-term training under experts through experience and observation.
