#gm-20

The 1985 Olds Calais was built using a new, revolutionary approach to car manufacturing simply called GM-20 program with one core mission: To take market share back from the imports. The process included computer design, work teams with extensive training, and over 200 robots for precise welds. Critical parts of the body were electro-chemically coated to resist rust. A computer-built, full-size model was used to assure precise fit, catching size discrepancies as small as $1/1000$th of an inch.

As the Washington Post wrote in 1984, General Motors spent $250 million alone on converting and updating its plants to the GM-20 methodology. It was brilliantly exceptional in manufacturing quality and the first time in its history, its facilities were about to build cars for other GM divisions internationally, too.
