What main focus does Lean methodology emphasize?

Lean methodology primarily emphasizes eliminating non-value-added activities, also known as waste, to enhance processes and deliver greater value to customers. The core principle of Lean is to maximize value by minimizing waste, which encompasses any activity that does not add direct value to the product or service from the customer's perspective. This approach leads to improved efficiency, reduced cycle times, and ultimately a higher quality outcome.

By focusing on eliminating waste, organizations can streamline their processes, engage more effectively with their workforce, and respond more swiftly to customer needs. This not only optimizes resource use but also fosters a culture of continuous improvement, where teams consistently look for ways to enhance processes and performance. In contrast, the other options either do not align with the fundamental principles of Lean or might represent secondary objectives rather than the primary focus of the methodology.
