Lean manufacturing principles

Definition

Lean manufacturing principles are a set of practices aimed at maximizing value while minimizing waste in the production process. This approach focuses on improving efficiency, reducing costs, and enhancing product quality through systematic elimination of non-value-added activities. By fostering a culture of continuous improvement, these principles align closely with concepts such as sustainability and resource optimization, which are central to creating a circular economy and practicing industrial ecology.
