Training Within Industry Has Its Roots in WWII, But Translates Well Today

Training Within Industry, or TWI, is a proven job training methodology that has been implemented successfully by manufacturers for decades (not to be confused with Urban Dictionary’s definition of “texting while intoxicated”). Basically, TWI was developed during World War II as part of the War Manpower Commission as a way to ready plants with skilled personnel in high-demand industries. More than 1.6 million people working in 16,500 plants received certification, with TWI later becoming the foundation for the Toyota Production System.
