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 methodology aims to enhance efficiency by streamlining processes, reducing waste, and improving product quality. By implementing lean principles, organizations can create a more responsive and flexible production environment. Techniques such as 5S, Kaizen, and Just-In-Time are commonly used to foster continuous improvement and ensure that every step in the manufacturing process adds value to the final product.
