There is a place in Fremont, California called New United Motor Manufacturing, Inc (NUMMI). The factory was an old General Motors plant and is now a joint venture between GM and Toyota. When it reopened for production in 1984, it was the first automotive joint venture plant in the United States. GM saw this joint venture as an opportunity to learn about Lean Manufacturing from the Japanese company, while Toyota gained its first manufacturing base in North America and a chance to implement its production system in an American labour environment.
NUMMI is now an award-winning facility which ranks with other Toyota plants among the most productive manufacturing operations in North America. GM places around 12 managers each year at the plant to learn lean techniques and has improved quality enough across the rest of its operations for it to show through on J.D. Power quality rankings. While the plant has been successful in adopting Lean, other GM plants have seen benefits. GM's Oshawa, Ontario plant received the 2006 JD Power Gold Plant Quality Award, the third time in the last five years.
Currently, the NUMMI plant produces the Toyota Corolla compact car, Toyota Tacoma pickup truck and the Pontiac Vibe station wagon. In the past, it has also produced the Geo Prizm, the later Chevrolet Prizm, and the Chevrolet Nova from 1984-1988 ( the Prism and Nova were also the Toyota Corolla); as well as the Toyota Voltz (2002-2004), the Japanese right-hand drive version of the Pontiac Vibe - both are based on the Toyota Matrix, which is manufactured in Cambridge, Ontario, Canada. Employment is nearly 5,500 workers. NUMMI is a union organization represented by The International Union, United Automobile, Aerospace and Agricultural Implement Workers of America (UAW) Local 2244. NUMMI sells 60% of their parts to Toyota and 40% to General Motors. NUMMI has 160 robots to build the three cars they do today.
