Training Within Industry (TWI) is a dynamic program of hands-on learning and practice, teaching essential skills for supervisors, team leaders, and anyone who directs the work of others. TWI is an essential element of Lean and continuous improvement programs around the world. The JI module is delivered over 12 hours – 10 in classroom, plus 2 hours of one-on-one coaching in the process. Supervisors and experienced workers will know how to instruct the people doing their jobs. Once skilled in instruction, supervisors can develop a well-trained workforce, resulting in reduced defects, less scrap and rework, fewer accidents and less tool and equipment damage.
