The following scenario was observed during a Job Instruction practice session at a factory in Amata Industrial Park, Dong Nai.

During the application of the 4-Step Job Instruction method, a Leadman (team leader) was invited to conduct a training session. He was an experienced operator on the production line – senior, approachable, and well-liked.

He stepped forward, well-prepared with materials and tools, and selected what he considered a relatively simple task. However, the training process turned out to be far more challenging than expected. He encountered common difficulties: the instruction appeared unstructured, hard to follow, and created confusion for the learner in understanding and correctly performing the task.

This situation clearly illustrates that effective instruction is not easy – even for highly experienced workers.

At that point, I asked him to pause and guided him to develop a Job Instruction Breakdown (JIB) – a structured tool designed to help organize and clarify the work. The JIB serves as a framework for thinking through the job in a systematic and complete manner.

As he worked through identifying the key points step by step, he began to reflect more carefully and logically on the process. The result was a well-structured Job Breakdown:

• The sequence of steps became clear and logical
• Key points were defined in a simple and easy-to-understand manner

The most valuable moment in this exercise was when he truly began to think deeply about the job – its requirements for quality, safety, and efficiency – and how to effectively transfer that knowledge to others. This process involved reflection, questioning, explaining, and validating – combined with his accumulated experience – to build a clear and practical Job Breakdown.

Another noteworthy point: the following day, the Leadman approached me to suggest revising one of the key points. He had identified a safer and more efficient method. This reinforces an important principle – when individuals are encouraged to think deeply, they naturally identify better ways of working.

The entire JIB development process took less than 30 minutes, using only pen, paper, observation, and structured thinking. If frontline leaders can consistently apply this approach with their teams, improvements in quality and productivity become both achievable and sustainable.

This transformation in the Leadman’s mindset and capability is exactly what TWI aims to enable and scale.
