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.

Due to differentiation and variation of items several concepts must be indicated into the product breakdown structure. Three concepts are involved in this differentiation, namely ALTERNATIVES, VARIANTS and REVISIONS. An ALTERNATIVE of an ITEM is considered as a substitute for that particular item, whereas a VARIANT is another option of an item which the consumer can choose. When an error occurred at a part or subassembly, it needs to be revised. This revisionsrevision indicatedindicats the change history of athe productITEM.
