13 as a result order 2 22 is displayed in the left position 31 and order 3 23 is displayed in the left center position 22 indicator 40 and indicator 44 are still correlated with order 3 23 respectively indicating that the runner is currently working on the order and the order has not been assembled yet further indicator 42 is still correlated with order 2 22 indicating that order 2 22 is ready to be presented or delivered to the customer assuming that the right position was filled before the presenter bump and new customer product order information is stored in the memory queue and is not being displayed it will now be displayed in the next available position to the right fig6 a and fig6 b illustrate an embodiment in which customer product order information changes positions while a customer order is being assembled an order may switch positions before it is assembled because it is of a higher priority than another order and needs to be assembled before another order the order management system 10 determines whether an order is of a higher priority based on predetermined criteria for example an order maybe of a higher priority than another because it was paid for before the other order fig6 a illustrates the display 13 before the order switches positions and fig6 b illustrates the display 13 after the order switches positions in fig6 a order 1 21 is in the left position 31 order 2 22 is in the left.
