Not sure why I thought I asked a question in my first post
My point is that JIT and where a prodcut are made are two separate things. The lead time involved in shipping a good needs to be factored into the JIT plan whether its made in the back, 100 mi away, or 10,000 mi away. A porrly setup JIT plan can fail for products that are made in the back of a store.
JIT can be used for both products made in America, and products made in China.
