## Definition

Job Instruction (JI) is a structured training methodology from Training Within Industry that teaches supervisors how to instruct workers quickly and correctly. The method uses job breakdown sheets identifying important steps, key points (what makes or breaks the step), and reasons why. Training follows four steps: Prepare the learner, Present the operation, Try out performance, Follow up. This systematic approach reduces training time, improves quality, and ensures consistency regardless of who conducts training.

## Examples

### Manufacturing

> A job breakdown sheet for assembly work listed: Step 1: Position base plate. Key point: Alignment pins must engage before pressing. Reason: Misalignment causes damage to circuit board. The trainer followed 4-step method: prepared the learner, demonstrated while explaining key points, had learner practice with coaching, then verified competency.

### Healthcare

> Nursing procedure training used job instruction format. Key points captured what textbooks often miss: "slight angle prevents air bubbles" with reason "air causes patient discomfort." Structured training reduced technique variation across shifts.

### Administrative

> Customer service training used job breakdown for difficult calls. Steps covered what to say; key points captured how to say it; reasons explained why tone matters. New hires achieved competency faster with fewer supervisor interventions.

## Key Points

- Job breakdown sheets: Important steps, key points, reasons why
- Four-step method: Prepare learner, Present operation, Try out, Follow up
- Key points capture the critical details that make or break quality/safety
- Standardized approach ensures consistent training quality

## Common Misconceptions

**Writing job breakdowns is extra work.** Initial investment in job breakdowns dramatically reduces training time and quality problems. Organizations track time to competency and defect rates to validate the return.

**Anyone can train if they know the job.** Knowing how to do a job doesn't mean knowing how to teach it. Job Instruction provides the teaching methodology that converts task expertise into effective instruction.
