During the crisis, Ford managed to stem its losses and return to profitability due in part to Chief Executive Alan Mulally's "One Ford" strategy, which helped cut engineering and production costs by creating a global manufacturing strategy. This push has been a cornerstone of Mulally's restructuring plan over the last seven years. Now Ford is exploring a strategy that may require change to the design of certain models so their parts can more easily shared with other models built in the region, Thai-Tang said. This will primary work in emerging markets, like South America and Thailand, where Ford builds fewer than the 100,000 vehicles required for the best price for a part. In a region like South America, cutting supplier costs may require Ford to tweak the design of the Focus compact car so that it has more in common with the automaker's small pickup truck, the Ford Ranger, Thai-Tang said.
