Product Structure
The Windchill Aerospace and Defense configuration management capabilities include an out-of-the-box product structure that is optimized to represent the hierarchical breakdown of the business and technical information involved in the enterprise development of an aerospace and defense product. For more information about the product context, see About Products.
Product Structure Overview
The following levels of the product structure are designed to manage product information according to the requirements of your site and the product components involved:
Upper Level—Includes information regarding the high-level hierarchy of a product, represented by its major areas, sections, zones, or other object designations your site prefers. Generally, the upper level structure is determined early and rarely changes once it has been established.
Configuration Level—Includes information regarding the functional elements that form the product. The configuration level of the product structure identifies points of configuration management and addresses how to meet their functional requirements.
Lower Level—Includes information regarding the physical assemblies, component parts, and standard parts that go into the design and manufacturing of the product.
Each level defines specific configurations and includes its own structure.

Other product structure configurations are possible, but the out-of-the-box features enable your site to most effectively manage the behaviors and relationships of different objects in a product.
