What is a sub assembly How is it useful in the assembly of a complex product that involves multiple parts?

A sub-assembly is a group of components or parts that are pre-assembled into a single unit before being incorporated into a larger product. This approach streamlines the manufacturing process by allowing different teams to work on various sub-assemblies simultaneously, enhancing efficiency and reducing assembly time. Additionally, using sub-assemblies can simplify troubleshooting and maintenance, as they can be replaced or repaired independently without disassembling the entire product. Overall, sub-assemblies facilitate more organized and modular production of complex products.
