TWI: The Missing Link in Lean
What is TWI?
The Training Within Industry (TWI) programs were developed by some of the most renowned training and management experts in the United States, and were rigorously tested in the field before being released to the public. When the TWI programs were introduced to Japan in the early 1950s, many Japanese companies enthusiastically adopted them and their underlying principles. Toyota was one such company.
The TWI programs are a critical component of Lean methodology, with the goal of developing a more skilled workforce, improving labor and management relations, enhancing productivity, and fostering a culture of continuous improvement. The TWI programs are the foundation of the Toyota Production System that we know today.
At the heart of the TWI programs are three "J" or "Jobs" programs: Job Instruction (JI), Job Methods (JM), and Job Relations (JR). These programs focus on instructing individuals on the best methods for performing their jobs, continuous improvement, and enhancing communication and leadership skills.
The JI training program equips supervisors with the tools and knowledge needed to deliver standardized training, fostering a culture of competence and consistency within the organization. This training includes explaining to frontline staff why their jobs are important; breaking down the job into logical steps and key points, and teaching the correct method of performing the task; confirming that the employees can do the task on their own; and following up to confirm that standard work practices are complied.
The JM program provides management with a technique whereby supervisors could acquire skills in improving methods so that problems are prevented and analytical methods are used to effectively resolve problems. Key to the JM training is teaching supervisors how to make the best use of the people, technology and resources available right now.
The JR program is a tool to help supervisors acquire leadership skills. This tool recognizes that job relationships are an important component of a supervisor's job and provides instruction about how to address "people" problems, such as morale issues or grievances. While personnel issues may prove an uncomfortable part of a supervisor's duties, not much can get done without the cooperation of people.
Benefits of TWI
The objective of TWI is to help supervisors develop a well-trained work force that can work more effectively and efficiently.
The benefits of TWI are:
• Get more done with less machines and manpower
• Improve quality, reduce scrap by achieving standard work across workers and shifts
• Reduce safety incidents
• Decrease training time, especially for temporary workers
• Reduce labor hours
• Reduce grievances
• Transfer knowledge from a skilled workforce to an unskilled or green workforce
TWI programs follow the Four-Step Learning Process developed by Charles Allen as described in the table below.
All TWI programs are designed to be simple, follow a blueprinted procedure, adopt a learn by doing principle and finally achieve the multiplication effect through a training cascade.
Companies that have implemented TWI have reported improvements of 25% and more in increased production, reduced training time, reduced scrap and reduced labor-hours.
Since 2009, Operational Excellence Consulting has helped various companies in the South-East Asian region to develop their TWI capability. The companies that we have helped include NSG Group (Vietnam), Transitions Optical (Philippines), Aprati Foods (Cambodia) and Wow Education (Singapore).
