What does a Bill of Material contain?

A Bill of Material (BOM) is a comprehensive document that provides a detailed list of all the components necessary to manufacture a product. This includes not only the standard parts but also any raw materials that are required in its fabrication. The BOM serves as a crucial reference by specifying quantities, part numbers, specifications, and descriptions of each item needed. It is essential for production planning, inventory management, and ensuring that the correct materials are on hand to create the final product.

The other options do not accurately define a BOM: installation instructions pertain to how to assemble or set up a product rather than detailing the materials; a list of tools needed is separate from the materials required and focuses on the procedures for production rather than the parts themselves. Therefore, the first choice is the most accurate representation of what a Bill of Material contains.
