What is a subassembly?

• A. When some parts are assembled into subassemblies which are then assembled into the main assembly
• B. A single loose part
• C. A group of unrelated parts
• D. An external vendor subcomponent

Answer: (A)

A subassembly is an intermediate unit formed by assembling several parts into a functional module that will be integrated into a larger product. This approach keeps complexity manageable, allows testing of the module before it’s added to the final product, and enables different teams to work on different sections in parallel. The description that parts are first put together into subassemblies and then those subassemblies are combined into the main assembly captures this practice exactly. A single loose part isn’t assembled with others, so it isn’t a subassembly. A group of unrelated parts isn’t a coordinated module. An external vendor subcomponent can be a subassembly if it is already an assembled module, but the important idea is the intermediate, assembled unit that flows into the main assembly.
