The TWI programs were developed in the United States over sixty years ago and played a major role in boosting industrial production to the levels required to win the Second World War. After the war, they were introduced around the world and, most notably, are still widely used in Japan today. The Toyota Production System approach of going to the source, observing in detail, and learning by doing was very much influenced by TWI and remains the backbone of Toyota’s standardization philosophy to this day. TWI is now being embraced throughout the US by companies to involve their people to sustain the gains from Lean and continuously improve.
Cornerstone of a Lean Culture
TWI is based on the principle that supervisors have five basic needs to be effective. Two of these needs are Knowledge of the Work and Knowledge of Responsibilities that are unique to each company and/or industry and are therefore provided locally. Supervisors also need Skills in order to perform within their role, regardless of their industry. The skills gained through TWI are especially important today as Lean pushes more responsibility and decision making down to the supervisor/team leader, and then to the people who do the work.
