Lean manufacturing primarily focuses on the minimization of waste within manufacturing processes. This concept is founded on the idea that by reducing waste — whether it's time, materials, or labor — organizations can improve efficiency, reduce costs, and enhance productivity. Waste can include overproduction, waiting times, excessive transport, over-processing, unnecessary inventory, defects, and unused talents of the workforce.

The principles of lean manufacturing emphasize creating value for customers while using fewer resources. This involves streamlining processes to eliminate steps that do not add value to the product, thereby allowing businesses to operate more efficiently. Consequently, the reduction of waste not only lowers costs but also contributes to a more sustainable production cycle, improving the overall quality and value delivered to customers.

While increased workforce utilization, reduction of production lead time, and higher levels of inventory can be byproducts of implementing lean practices, they are not the primary objectives of lean manufacturing. The core aim is to identify and eliminate waste in all its forms to create a more efficient operating environment.
