Lean manufacturing is the concept that focuses on improving efficiency in production by minimizing waste while maximizing productivity. This methodology seeks to identify and eliminate non-value-added activities in the production process, thereby streamlining operations and achieving higher efficiency. By emphasizing continuous improvement and respect for people, lean principles help organizations create more value for customers with fewer resources.

While just-in-time production also aims to reduce waste by ensuring that materials arrive only when needed, it is primarily concerned with inventory management rather than the broader context of overall waste elimination in processes. Six Sigma is a data-driven approach aimed at reducing defects and improving quality, but it does not specifically focus on waste reduction in the same comprehensive manner as lean manufacturing. Batch production, on the other hand, typically involves producing goods in groups or batches, which can sometimes lead to inefficiencies and excess inventory, counter to the principles of waste reduction promoted by lean practices.
