Which item is NOT typically included in a BOM?

• A. Part numbers and descriptions
• B. Quantities
• C. Supplier information
• D. Machine settings for manufacturing process

Answer: (D)

The concept here is what a Bill of Materials includes: it lists the components and essential data needed to assemble a product. The item that is not typically part of the BOM is machine settings for the manufacturing process. Machine settings—such as spindle speeds, feed rates, and setup configurations—are details of how to manufacture, and they belong in process instructions or routing/operation sheets rather than in the component list.

A BOM focuses on what components are needed, how many of each are required, and often who supplies them. Part numbers and descriptions identify each component, and quantities specify the amount needed. Supplier information is frequently included to assist with sourcing and procurement. But the specific manufacturing parameters to run the equipment are separate from the BOM, which is why that option is the best choice.
