The terms explained in this topic help you manage your bill of materials (BOM) data.

The term	Refers to
Design	The virtual representation of a part. It represents what a part will look like in its floor position. For example, represents a wheel. Designs are attached to design revisions in Teamcenter.
Part	The primary component of a product. For example, the product CrossKart consists of different parts such as Wheel, Engine, and Chassis. Each part is saved as a part revision in Teamcenter.
Flexible part	A part that can be used in a product in various states. Examples include a coil spring, hose pipe, and wire harness.
Bought out part	A part that is purchased and not manufactured in-house.
Part structure (Assembly BOM)	An Assembly BOM is a BOM structure that is based on occurrence in which an assembly owns the lifecycle of the occurrence of the child parts.
Part occurrence	An instance of a part in a Assembly BOM. For example, the wheel assembly contains the part occurrences of Tire, Rim, and Valve.
Design	A virtual representation of a part.
Design structure	A design structure of a product to represent it virtually from a geometrical standpoint. It consists of designs, which contain the design information such as CAD and product manufacturing information (PMI).
Design occurrence	An occurrence of a design in a design structure. A design occurrence contains the position information of a part. For example, the design occurrence of a wheel contains the information related to its placement in Crosskart.
Design-part alignment	The alignment between a design and a part. It shows what a part will look like in its floor position.
Design occurrence-part occurrence alignment	The alignment between a design occurrence and a part occurrence. It shows what a part will look like when placed in a product.
