"Just-in-time" parts production    The parts plant produces and ships goods as the assembly plant orders them, delivering the parts "just in time." This production process results in limited inventory, which can save money. Less investment is needed for warehouse space and stock.    "Just-in-time" delivery also enables mistakes to be caught before vast quantities of products are made. The danger of "just-in-time" delivery is that if parts production is interrupted, as with the Delphi strike, no stock is available for continued assembly, effectively shutting down the plant.
