TWI: The Missing Link in Lean
What is TWI?
Training Within Industry (TWI) is an integral part of Lean and aims to deliver a better-skilled workforce, improved labor and management relations, productivity improvements and a focus on continuous improvement.
Central to TWI are three "J" or "Jobs" programs called Job Instruction (JI), Job Methods (JM) and Job Relations (JR). These programs address the processes of instructing people on the best way to perform jobs, continuous improvement, and improved communication and leadership skills.
Job Instruction (JI)
The JI training program teaches supervisors how to instruct the people doing the jobs. 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.
Job Methods (JM)
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.
Job Relations (JR)
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.
In September 1990, my colleague and I participated in a technical training program for instructors held at the Panasonic Overseas Training Center and the Production Engineering College in Osaka, Japan for a period of two months.
During that time, we were newly hired technical training instructors at the Panasonic Regional Training Center located in Singapore. Our key roles were to educate and train the company's supervisors, engineers and technicians within the ASEAN region in shop-floor manufacturing excellence.
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).
