Build effective on-the-job training systems with TWI Job Instruction. Develop skills and onboard new employees faster.

TWI Job Instruction builds and sustains a reliable system for training employees at work. Supervisors learn to prepare clear job breakdowns and teach each task in a consistent way.

TWI Job Instruction in daily operations

First, the method develops practical instruction skills among supervisors and experienced employees. As a result, new people reach the required standard faster and with fewer errors.

Moreover, consistent instruction supports productivity, safety and quality. It also reduces defects and employee turnover while stabilizing processes across the organization.

Since 2007, we have developed the TWI program first in Europe and later worldwide.
Across an eight-year automotive project, we rolled out TWI Job Instruction in 60 plants on four continents and in more than 20 countries.
In addition, we offer original certified TWI Instructor and TWI Trainer courses aligned with international standards.
Moreover, we deliver open TWI Job Instruction training for leading companies across many industries.
We also authored hundreds of publications and the book “Standardized Work with TWI”, published in the United States.
To support digitization, we developed eTWI for creating and managing TWI instructions.
So far, our team has conducted more than 1,000 practical TWI workshops in over 200 companies.
Through an international trainer network, we deliver implementations across countries and industries.
Finally, we use AI to create TWI instructions with our KaizenUp AI application.

Our book “Standardized Work with TWI” was published in the United States in 2015 and has become one of the key international resources on practical work standardization.
It focuses on how to implement standardization effectively, using the principles of the TWI Job Instruction (JI) method and Lean practices.
Readers will find detailed guidance on creating Standardized Work Instructions, designing Poka Yoke systems, developing Skill Matrices, and running Train-the-Trainers workshops to build competence within their own organizations.

This book reflects our hands-on experience from hundreds of implementations across industries — helping leaders understand not only what to standardize, but also how and why to do it.

What is the Certified TWI Job Instruction program?

Certified TWI Job Instruction program

The Certified TWI Job Instruction (JI) program by Leantrix is an 8-module certification course focused on developing practical skills in training employees effectively on the job.
Participants learn how to:

Prepare and deliver structured on-the-job training sessions,
Develop Standard Operating Procedures (SOPs) and Job Breakdown Sheets,
Build and maintain a Skill Matrix,
Standardize work instructions using digital tools.

The certification combines real workplace exercises with structured coaching sessions, ensuring that participants not only understand the TWI JI method but can also apply it directly in their production or service environment.

What are the four steps of the TWI Job Instruction method?

The TWI JI method is built around a simple yet powerful four-step process:

Prepare the Worker – create the right learning conditions and explain the purpose of the job.
Present the Operation – demonstrate the job using clear steps and key points.
Try Out Performance – allow the trainee to perform the job while observing and correcting mistakes.
Follow Up – check progress, encourage feedback, and provide continuous support.

These four steps form the foundation of effective skill transfer and are still used in leading manufacturing and service organizations around the world.

What is the purpose of TWI Job Instruction training?

The goal of TWI JI is to ensure that every employee performs their job safely, correctly, and consistently.
By teaching supervisors how to train operators systematically, companies can:

Shorten onboarding time by up to 25%,
Reduce quality defects and rework,
Improve safety and process stability,
Develop a culture of standard work and continuous improvement.

Who should participate in the Certified TWI Job Instruction program?

Who uses TWI Job Instruction?

The program is designed for:

Team Leaders, Supervisors, and Trainers responsible for training new employees,
Lean and HR professionals building skill development systems,
Production Managers implementing work standardization and SOP management.

It is also suitable for service and healthcare organizations seeking to build consistent, repeatable processes for onboarding and skills development.

What is a Skill Matrix, and how is it used in TWI Job Instruction?

A Skill Matrix (also called a Competence Matrix) is a visual management tool that maps employees’ skills against the tasks or machines they can perform.
Within the TWI JI framework, it helps leaders to:

Identify who can train others and who still needs instruction,
Plan training priorities based on production needs,
Track progress and ensure workforce flexibility.
Leantrix supports digital Skill Matrix implementation, allowing real-time updates and analytics.

What is the relationship between TWI Job Instruction and Standard Work Instructions (SOPs)?

TWI Job Instruction and work standards

TWI JI provides the foundation for creating Standard Operating Procedures (SOPs) and Job Breakdown Sheets (JBS).
Each instruction is structured around the three TWI JI elements:

Major Steps – what must be done,
Key Points – how to do it safely and accurately,
Reasons – why each step or key point matters.

This approach ensures that SOPs are practical, visual, and effective for both training and auditing.

How does TWI Job Instruction improve safety and quality?

TWI JI directly influences work safety and product quality by eliminating variation in how jobs are performed.
When every operator follows the same standard, the risk of human error is reduced.
The method also integrates naturally with safety systems (TWI Job Safety, JHRA) and quality frameworks such as ISO 9001 or IATF 16949.

How is TWI Job Instruction connected with Lean Management?

TWI Job Instruction is one of the historical roots of Lean Management.
It was introduced to Japan after World War II and became part of the Toyota Production System (TPS).
Toyota used the method to train leaders who could teach, improve, and lead effectively – forming the cultural basis of Kaizen and continuous improvement.
Today, TWI JI remains the essential foundation for any Lean transformation focused on people development and process stability.
