The user keys in part descriptions, and the system automatically draws a hierarchical tree structure on the computer display. The user is then prompted to consider, part by part, all of the parts in the product. A series of pop-up menus guide the user through manufacturing and planning for the part. Based on the data input by the user, the system then generates a qualified parts list and computes an estimated cost figure for the product using manufacturing information gathered by the conceptual design tool during product release planning.Other References
