Lean Manufacturing

Definition

Lean manufacturing is a production practice that considers the expenditure of resources in any aspect other than the direct creation of value for the end customer to be wasteful and thus a target for elimination. This approach streamlines processes, improves efficiency, and enhances product quality by reducing waste in various forms, including time, materials, and labor. By focusing on optimizing flow and minimizing waste, lean manufacturing leverages technological innovations to enhance overall manufacturing performance.

5 Must Know Facts For Your Next Test
