​
What is TWI?
 
Origin & Relevance

TWI (Training Within Industry) was developed in the U.S. and later adopted in Japan in the 1950s. It’s foundational in Lean methodology, shaping practices in companies such as Toyota.
​

Core Components – JI, JM & JR

 

Job Instruction (JI): Teach employees to do jobs correctly, safely, and consistently. 
 

Job Methods (JM): Improve how work is done—streamline workflows, reduce unnecessary steps, and optimize current resources. 
 

Job Relations (JR): Equip supervisors to build trust, resolve conflict, and lead people well.

Why TWI Matters


Build Stability & Consistency


TWI standardises how supervisors teach, coach, and lead—reducing variation and reinforcing quality. 

​

Improve Productivity & Quality
 

Companies using TWI have reported large gains: reduced training times, less scrap, fewer labor hours, and higher output. 

​

Strengthen Supervisory Capability & Labor Relations
 

The programs enhance supervisor skills, improve relations with teams, and support a culture of continuous improvement.
