Training Within Industry (TWI)

Training Within Industry, or TWI for short, is a set of three hands-on, "go to gemba" style training methodologies developed by the United States TWI Service at the beginning of World War II. Due to the war effort, the US lost most of their skilled workforce to military service, while at the same time it saw massive increased demand for new and existing product production. This created a problem to solve that many of us still face today. How do you rapidly train an unskilled workforce in as little time as possible, while at the same time reducing scrap and increase production? The answer is three sets of proven, efficient training methodologies.
