In Summary In broad terms, the first Japanisation phase of re-structuring the automotive components and materials supply chain saw a factor ten reduction in the numbers of such suppliers per model or per plant, from 2-3,000 to 2-300. The modularisation phase will see the emergence of another factor ten reduction in numbers, with perhaps 20 to 30 suppliers per model or per plant. In practice, there will still be more direct suppliers than this, for example those supplying bolts or screws to the final assembly line, but the bulk of the (increased) outsourced value will be captured by the few modular suppliers.
