Product structure is a hierarchical decomposition of a product, typically known as the [[bill of materials]] (BOM).

As business becomes more responsive to unique consumer tastes and derivative products grow to meet the unique configurations, BOM management can become unmanageable. For manufacturers, a bill of materials (BOM) is a critical product information record that lists the raw materials, assemblies, components, parts and the quantities of each needed to manufacture a product.<ref>{{cite web|title=Arena Solutions BOM Control|url=http://www.arenasolutions.com/products/plm/bom-software|website=Arena Solutions}}</ref>

Advanced modeling techniques are necessary to cope with configurable products where changing a small part of a product can have multiple impacts on other product structure models. Concepts within this entry are all caps locked in order to indicate these concepts.

[[Image:Product_structure_modeling_metaProduct structure modeling meta-data_model1data model1.gif|right|thumb|300px|Figure 1: product structure concepts]]Figure 1 illustrates the concepts that are important to the structure of a [[Product (business)|product]]. This is a [[Meta-modeling technique|meta-data model]], which can be used for modeling the instances in a specific case of product structuring.

The core of the product structure is illustrated by the product components (ITEMS) and their RELATIONSHIPS. Thus, this involves the linking between ITEMS related to the [[Product (business)|product]].

The ASSEMBLY can exist of SUBASSEMBLIES and PARTS, whereas SUBASSEMBLIES can also consist of other SUBASSEMBLIES or PARTS. Thus this is typically hierarchically ordered. These concepts are generalized into the concept of ITEM. This classification is overlapping, because a SUBASSEMBLY could be a PART in another ASSEMBLY configuration.

Line 18:

Product structure views are made upon several activity domains within the company. Due to the fact not everyone in the company has to have a detailed overview of the product several components with their attributes can be extracted.

When the MASTER STRUCTURE is made out of the several items of the product assembly, multiple views can be made upon this MASTER STRUCTURE. Thus this MASTER STRUCTURE contains every item in detail, which is important to the ASSEMBLY of the product.[[Image:Product_structure_modeling_metaProduct structure modeling meta-data_model2data model2.gif|centre|thumb|500px|Figure 2: Different product structure views]]

===Documenting===

When the MASTER STRUCTURE of the car is created one must link this structure with documents which contains the product definition of this specific car. Primarily, this consists of an extensive description of the car which is linked to the MASTER STRUCTURE of this product.
