What is Training Within Industry (TWI)?

Unveiling the Power of Training Within Industry (TWI): Transforming Workforce Training for Success

Training Within Industry (TWI) emerged during one of the most challenging periods of the 20th century—World War II. Developed as a critical tool to train a new generation of workers rapidly and efficiently, TWI played a crucial role in scaling up industrial production when many experienced workers were sent to fight on the front lines. Despite its wartime origins, the principles of TWI have endured and evolved, proving invaluable in today’s fast-paced, competitive industries. This blog explores the history of TWI, its key components, and how its methods continue to shape modern workforce training and Lean practices.

The Birth of TWI: A Response to Crisis

In 1940, as the U.S. entered World War II, there was an urgent need to rapidly expand industrial production, particularly in sectors related to defense. Factories needed to train thousands of new workers, many of whom had little or no experience in industrial work. TWI was created to meet this challenge, with a focus on “doing more with less.” Supervisors were not only tasked with managing teams but also with teaching new employees how to work efficiently and safely. This approach played a pivotal role in accelerating production while maintaining high standards of quality.

1950: The Global Impact of TWI

While TWI originated in the U.S., its influence quickly spread across the globe. One of the most notable adopters was Japan, particularly Toyota. After the war, Japanese industries were eager to rebuild and modernize, and they saw great potential in the TWI approach. Toyota integrated TWI into its production system, laying the groundwork for what would later become Lean Manufacturing. This evolution ensured that TWI principles remained relevant well beyond the war era, becoming a foundational element of continuous improvement and operational efficiency in industries around the world.

Unlocking the TWI Toolbox

TWI is built around three core modules, each designed to address a specific aspect of workforce training. These modules are still used in many Lean environments today and provide a structured approach to training and improving both employees and processes.

1. Job Instruction (JI):

The Job Instruction module focuses on standardizing work processes. It ensures that workers are trained in the correct methods for their tasks, which leads to consistent output and reduces variability. JI is based on a four-step process:

• Preparation: Setting up the worker for success by ensuring they have the right tools, knowledge, and environment.
• Presentation: Demonstrating the correct way to perform a task.
• Trial: Allowing the worker to try the task under supervision to ensure they understand it.
• Follow-up: Monitoring the worker’s performance over time to ensure the task is performed consistently.

The primary goal of JI is to establish a reliable, repeatable process that ensures quality and safety.

2. Job Methods (JM):

Job Methods takes the concept of standardized work further by focusing on improving the way tasks are performed. Through JM, workers are encouraged to break down tasks and identify inefficiencies or unnecessary steps. The four steps in JM are:

• Breakdown the Job: Analyze each task and identify areas for improvement.
• Question Each Detail: Challenge each aspect of the task—why is it done this way, and can it be improved?
• Develop New Methods: Create improved methods based on the analysis.
• Apply the New Methods: Implement the improved processes and monitor their effectiveness.

JM emphasizes continuous improvement, making it a cornerstone of Lean practices and Kaizen activities.

3. Job Relations (JR):

Job Relations focuses on the people aspect of the workplace. It teaches supervisors how to build positive relationships with their teams, resolve conflicts, and foster a collaborative work environment. The key elements of JR include:

• Handle Problems Quickly: Address issues before they escalate.
• Provide Clear Direction: Ensure that all team members understand their roles and expectations.
• Build Trust: Foster an environment where employees feel valued and respected.
• Encourage Growth: Support employee development and encourage them to take on new challenges.

Strong job relations lead to better teamwork, higher morale, and increased productivity.

Beyond the Core: TWI Expands

In addition to the three main modules, TWI expanded to include other important areas of focus, such as Job Safety (JS) and Problem Solving (PS). These modules helped industries develop safer work environments and equipped workers with the tools to address challenges proactively.

• Job Safety (JS): Focuses on identifying and mitigating workplace risks to create a safer environment for employees.
• Problem Solving (PS): Encourages workers to take a proactive approach to resolving issues by identifying root causes and implementing sustainable solutions.

These additions to the TWI framework made it even more relevant to industries striving for operational excellence.

TWI in Modern Industry: A Lasting Legacy

While TWI was born out of necessity during World War II, its principles have proven to be timeless. Today, TWI remains a vital part of Lean Manufacturing and continuous improvement initiatives. Its emphasis on standardization, efficiency, and people development resonates in a world where industries must constantly adapt to new challenges.

Many companies across various sectors have embraced TWI as a tool for building a more skilled, engaged, and flexible workforce. By using TWI’s structured training methods, organizations can reduce variability in processes, enhance safety, and improve overall productivity. Moreover, TWI’s focus on relationship-building through Job Relations helps create a positive work environment, where employees feel empowered and motivated to contribute to the company’s success.
