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 aims to optimize efficiency, reduce costs, and improve quality by focusing on value-adding activities while minimizing waste throughout the supply chain. It encourages a culture of continuous improvement and responsiveness to customer needs.
