Job Instruction Training is a structured method for teaching work safely, correctly, and consistently by breaking jobs into key steps, key points, and reasons why.
Definition
Job Instruction Training (JIT), often connected with Training Within Industry, is a structured method for teaching a job by preparing the learner, presenting the operation, trying out performance, and following up. The job is broken into important steps, key points, and reasons for those key points.
It supports standard work, safety, quality, onboarding, cross-training, and skill transfer. It is different from telling someone to shadow an experienced worker without a defined method.
History
Training Within Industry was developed during World War II to rapidly train workers for industrial production. Job Instruction became one of its core programs and later influenced Lean training and standard work practice.
The method remains relevant because poor training is a common contributor to variation, defects, injuries, and slow onboarding.
When to Use
Use Job Instruction for new employees, job changes, critical quality tasks, safety-sensitive work, cross-training, temporary labor, process changes, and standard work rollout. It is especially useful when a task has key points that are easy to miss.
It should be used before relying on audits or retraining to fix recurring errors.
Step-by-Step
- Prepare the worker and explain the job purpose.
- Break the job into important steps, key points, and reasons.
- Demonstrate the job clearly and patiently.
- Have the learner try the job while explaining steps and key points.
- Correct errors immediately without blame.
- Confirm understanding of reasons why.
- Follow up with observation and coaching.
- Update training material when the standard changes.
Examples
- Assembly: A trainer teaches torque sequence, tool angle, and verification reason.
- Healthcare: A process owner trains patient-ID checks using key points and reasons.
- Warehouse: Pick verification is taught with barcode, location, and label checks.
- Office work: A billing task is broken into entry steps, exception checks, and approval rules.
Common Pitfalls
- Calling shadowing training.
- No job breakdown sheet.
- Teaching what to do without why it matters.
- Skipping follow-up.
- Training to outdated standards.
- Assuming experienced workers are automatically good trainers.
