You are managing an order processing facility where employees pick the customer orders from the warehouse, package, and deliver them to postal services. There are bar-code scanners and conveyors to facilitate finding and moving items through the facility. Deliveries to each state are grouped together as part of your deal with postal services for a lower rate. There are problems in order processing, including orders filled with wrong items, orders with the right items but the wrong number of some items, and finding packages being shipped to the wrong state. Prepare a cause-and-effect diagram to show the causes of these problems and explain your solution for each.
