TWI (Training Within Industry) – Job Instructions

Formation / Ressources humaines

Course Description

How to train a lot of people... quickly!

TWI is hailed as one of the most effective approaches for developing the skills of experienced Operators and Leaders in terms of instructing, improving and problem-solving. It is not surprising, then, that it is an essential element of Lean and Continuous Improvement programs around the world, as well as serving as the foundation for the Toyota Production System (TPS).

According to Wikipedia, the Training Within Industry (TWI) approach was developed by the United States’ War Manpower Commission during the Second World War and is said to have contributed to the Allied Forces victory by training unskilled personnel to replace those being conscripted into the army.  The factories were able to be kept running so that the troops could be supplied with essential material.  It is estimated that by the end of WWII, over 1.6 million workers in over 16,500 plants had received a certification using the TWI method.

As more and more subject-matter experts are poised to retire and their successors need to be trained, you need a consistent training method that will result in a stable process (standard work) on which a Lean approach can be built.
