Abstract: A system and method for managing changes to items associated with a complex system of inter-related items. The inventive system includes a database having a plurality of records, wherein each record includes information concerning an item associated with the assembled end product. The information contained in each record includes an identification of other items that could be affected by a change to the item associated with the record. The system further includes a computer-user interface displaying a user-updateable list of affected items and a user-updateable list of non-affected items. The list of affected items and the list of non-affected items are created by assigning items that may be affected by a change to one of these lists.
