The primary focus of Lean manufacturing is to reduce waste and improve efficiency. This methodology aims to streamline production processes by eliminating anything that does not add value to the product or service. By focusing on maximizing efficiency, Lean practices help companies minimize costs and enhance productivity. This is achieved through various techniques like continuous improvement, value stream mapping, and just-in-time production.

In this context, reducing waste refers not only to minimizing physical waste, such as materials or products that are discarded, but also to inefficiencies in processes, time wasted, and unnecessary movement. Lean manufacturing seeks to create a smoother workflow, ensuring that resources are used effectively and that products are delivered more rapidly to the customer. This not only benefits the organization in terms of cost savings and increased output but also can lead to greater customer satisfaction as products are delivered more quickly and reliably.

The other options are less aligned with Lean principles. Increasing product variety may complicate processes and lead to more waste, enhancing employee benefits, while important for overall workplace morale and retention, is not a core tenet of Lean, and maximizing inventory contradicts the Lean principle of just-in-time production. Lean emphasizes having just enough inventory to meet production needs without overstocking, thereby reducing waste associated with excess inventory.
