Ohno once said, “At Toyota we have no warehouses.” Toyota wants Just-in-time. You deliver what is needed when it is needed in the quantity needed.
Ohno once said that it is better for the entire factory to stop when there are external problems than to have any inventory – buffer stock.
Yes, the virus has interpreted your supply chains, but maybe you should reexamine your supply chains.
Toyota has been disrupted many times in the past but I don’t believe they have changed their basic philosophy that inventory is a waste.
