• For all tasks of type “packing,” there is a packing list that specifies the contents of the packages. There are many different packing lists to produce different packages, such as basic medical packages, child care packages, food packages, etc. Each packing list has a packing list ID number, packing list name, and a packing list description, which describes the items that ideally go into making that type of package. Every packing task is associated with only one packing list. A packing list may not be associated with any tasks, or may be associated with many tasks. Tasks that are not packing tasks are not associated with any packing list.
