Engineering bill of materials

An engineering bill of materials (EBOM) is a type of bill of materials (BOM) reflecting the product as designed by engineering.

The EBOM is not related to modular BOM or configurable BOM (CBOM) concepts, as modular and configurable BOMs are used to reflect selection of items to create saleable end-products.

The EBOM concept aligns to sales BOMs (as sold), service BOMs (as changed based on changes due to field service).

This BOM includes all substitute and alternate part numbers, and includes parts that are contained in drawing notes.
