Figure 16.14 shows such a situation drawn out on the Future State Map. Above the supermarket is a FIFO lane. This allows for customized product, or for the very occasional product not supermarketed, to bypass this controlled point in the value stream and be handled “next up.” The FIFO lane can be placed above the supermarket if it is a higher priority than supermarket work, or beneath the supermarket if it is more important to respond to the supermarket first.
