Training Within Industry is the structural genesis of Lean Manufacturing and the heart of Kaizen - the practice of continuous improvements. From the Toyota Production System to the standardization of training retail sales clerks, Training Within Industry is one of the original document sets provided to Toyota after World War 2 by the United States Government, and it proves that Toyota's true innovation came from these structured documents. The training material contained in this 8.5 X 11 inches, 86 page Training Within Industry book is as applicable today as it was when it was first written down, decades ago.
