Revisit the below figure. Why do you think there are so many suppliers for a single car? Wouldn't it be easier to have fewer suppliers? Can you find an example where a major OEM (e.g., Ford, Nissan, or Mercedes) made supply-based rationalization a strategic priority? How did your OEM do this? What role did supplier integration play in helping the auto OEM become more competitive?
