How do standardized parts help workers assemble products quickly?

Standardized, or interchangeable parts, are identical components that can be substituted for one another during the manufacturing process. These parts are fundamental to mass production because they eliminate the need for custom fitting or manual adjustment of individual components.

Because every part is manufactured to precise tolerances, workers on an assembly line do not need to spend time filing, grinding, or selecting specific pieces to ensure they fit together. Instead, they can quickly attach components as the product moves along a conveyor, knowing that any part taken from the supply bin will fit the assembly perfectly. This consistency allows for a continuous, high-speed flow of work, as tasks are simplified and synchronized to ensure that parts and tools are delivered to the worker exactly when needed.123
