Engineering Bill of Material (EBOM) EBOM is created in Engineering phase, are typically driven from the CAD tools and are usually centric to the final assembly list of parts or components that make up the as designed or EBOM. EBOM is a list of all of the parts in the a product’s design of a product. As it is specific to the design and will not necessarily list all of the components and materials needed to manufacture a product. An engineering bill of materials (EBOM) should include a list of parts, components, and materials and detailed engineering information such as specifications, tolerances, and standards. Organized with regards to how the product is designed List of all the parts in the product’s design Includes a list of parts, components, and materials Also includes detailed engineering information such as specifications, tolerances, and standards Manufacturing Bill of Material (MBOM) MBOM is driven by the EBOM. MBOM's make up the end item, or product as shipped. MBOM is the
