The Training Within Industry Service (TWI) was established on June 22, 1940 after the fall of France to support the anticipated need to increase industrial production for the war effort partially based on a similar effort during WW1. This was to be a temporary volunteer staff from industry. The first volunteers recruited were C.R. Dooley and Walter Dietz. They were requested for six weeks…and ended up staying until the close of the organization in September 1945.

“The TWI organization was planned in 1940 as a country-wide network of industrial training men each of whom would (1) establish a local industrial panel of volunteer consultants, and (2) serve as a link in a national chain in order to circulate useful techniques among the various industrial areas of the country.” The directors of the TWI Service established the TWI Foundation to continue their research and to improve the "J" programs.

Until August 2008, most of the TWI experts thought that we had almost all of the important materials that were available (the 10-hour Sessions manuals and Bulletins). Some of the major finds were the revised manuals that were completed by the original TWI Directors when the established the TWI Foundation.

In addition to the updated Job Instruction, Job Methods, and Job Relations manuals, the discovery of several "Staff Only" manuals uncovered how they organized the implementation of training in companies.

We continue to look for archival materials in the US and locations overseas. Our current collection now exceeds well over 30,000 images from the various Archive collections.

If you also research the TWI materials or early Lean development, we actively share our collection for academic purposes.
