TWI: The Missing Link in Lean
At Operational Excellence Consulting, our Training Within Industry (TWI) programs equip supervisors and frontline leaders with proven tools: Job Instruction, Job Methods, and Job Relations. We help you reduce rework, improve quality, and strengthen team performance through structured, experiential learning.
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.
