Assembly Item

This information object represents the identification of, and the reference to, a component in product assembly structure

Assembly Item Relationship

This information object identifies the relationship between configuration items in a product assembly structure. It is essentially used to establish the parent child relationships between assembly items.

Product

This is a physical instance of a Product Design. Individual products are typically identified by a serial number, and batches are typically identified by a batch number. Both of these would be captured by the referenced Identifier information object.

Product Assembly

A hierarchical structure which depicts parent/child relationships and is constructed to represent how the build of the product will be achieved and the impact of any changes made to the product. The product composition (i.e. relationships and quantity of parts that comprise the product) is determined from its Product Design.

Product Design

This is the aggregated set of information that constitutes the design of a product. Product designs can be of any "level" of product, from individual nuts and bolts, up to complete equipments, systems and platforms. Product designs are typically identified by a design authority part number, and when fully specified, will have a detailed drawing/product model associated with them that contain the level of detail that enables instances of the physical elements of the design to be manufactured and/or assembled. Those physical elements will be fully specified by their own Product Design. Product designs will typically also contain performance specifications, physical characteristcs (such as dimensions, weight and material specifications), and other charateristics such as cost. Prior to this level of detail being defined, the product design process may involve specification of functions, conceptual physical design/general layout design and identification of spatial zones within the design..
