Yoi kangae, yoi shina! that's Toyota-speak for "Good thinking means good products." The slogan is emblazoned on a giant banner hanging across the company's Takaoka assembly plant, an hour outside the city of Nagoya. Plenty of good thinking has gone into the high-tech ballet that's performed here 17 hours a day. Six separate car models -- from the Corolla compact to the new youth-oriented Scion xB -- glide along on a single production line in any of a half-dozen colors. Overhead, car doors flow by on a conveyor belt that descends to floor level and drops off the right door in the correct color for each vehicle. This efficiency means Takaoka workers can build a car in just 20 hours.
The combination of speed and flexibility is world class. More important, a similar dance is happening at 30 Toyota plants worldwide, with some able to make as many as eight different models on the same line. That is leading to a monster increase in productivity and market responsiveness -- all part of the company's obsession with what President Fujio Cho calls "the criticality of speed."
