Which listing shows all subassemblies, parts, and raw materials for a parent assembly and quantities, used to determine items for requisitions and production orders?

• A. Routing sheet
• B. Bill of Materials (BOM)
• C. Production order
• D. Master production schedule

Answer: (B)

A Bill of Materials lists every subassembly, part, and raw material needed to build a parent item, with the exact quantities for each. That complete, structured listing is what you use to figure out what needs to be requisitioned from purchasing and what items should be included in production orders. It can be single-level or multi-level, showing how components nest into subassemblies and the finished product, which gives a full picture of material requirements for planning and manufacturing.

Routing sheets describe the sequence of operations, times, and resources required to manufacture, but they don’t list components or quantities. A production order is the instruction to actually manufacture, not a bill of what’s needed. The master production schedule outlines what to produce and when, at a high level, without detailing the components needed.
