Final answer:
Fordism corporations rely on mass production and centralized systems, while post-Fordism adopts flexible and efficient production strategies like just-in-time manufacturing.
Step-by-step explanation:
One of the principal differences between Fordism corporations and post-Fordism corporations is that the former are characterized by mass production with an integrated and centralized system, as evident in the example of Ford's River Rouge factory. This factory represented a traditional Fordism approach, with raw materials like iron ore being delivered to one end and finished products like Ford Mustangs coming out the other, indicative of a linear and fixed production process. In contrast, post-Fordism corporations typically embrace more flexible production strategies like just-in-time manufacturing, which focuses on efficiency and responsiveness to the market rather than mass production. The River Rouge plant's closure in 2004 highlighted the transition from Fordism production techniques to more modern manufacturing approaches that prioritize spatial economics and flexibility.
