TWI has it origins (very loosely) in World War I, when Charles R. Allen developed his four-point method of Preparation, Presentation, Application, and Testing to train shipyard workers. He published it in his book “The Instructor, the Man and the Job; a Hand Book for Instructors of Industrial and Vocational Subjects” (1919).
