In Lean manufacturing, what does muda mean?

• A. Statistical measure
• B. Value-added activity
• C. Customer requirement
• D. Waste

Answer: (D)

Muda means waste in Lean manufacturing—non-value-added activity that the customer wouldn’t be willing to pay for. The whole aim of Lean is to identify and remove muda so work flows smoothly, lead times shrink, and costs fall. It sits with other ideas like mura (unevenness) and muri (overburden), but the important point here is that muda is waste: things produced or done that do not add value from the customer’s perspective. Think of examples like producing more parts than needed (overproduction), waiting for the next step, moving materials or people more than necessary, extra processing, holding unnecessary inventory, or defects requiring rework. These are wastes because they do not transform the product in a way the customer values and they add cost without adding value. That’s why waste is the best fit. A statistical measure isn’t what muda refers to, value-added activity is the opposite of muda, and a customer requirement is something the product must satisfy, not the inefficiencies Lean targets.
