What is the Engineering BOM (eBOM)?

An engineering BOM is created at the very beginning of product design by engineers in either CAD or EDA, listing items that will be necessary to manufacture a particular product. They are a crucial step in the product lifecycle because a well-laid-out engineering BOM can help manufacturers avoid problems down the line. 

One key step to establishing a fully digitized manufacturing process that works concurrently with product design is establishing an engineering bill of materials that’s used to derive the manufacturing BOM and service BOM—and remains connected.
