The term Waste refers to which concept?

A value-added activity

A defect that remains in the final product

An unnecessary design change

The work element that adds no value to the product or service in the eyes of the customers

Waste in Lean thinking is anything that does not add value from the customer’s perspective. The statement that identifies waste as the work element that adds no value to the product or service in the eyes of the customers best captures this idea, because it focuses on value as perceived by the customer and on removing activities that do not contribute to that value.

A value-added activity is the opposite of waste, since it changes the product or service in a way the customer would pay for. A defect that remains in the final product is a quality issue, not the general definition of waste. An unnecessary design change can be a form of waste, but waste is defined broadly as any work that adds no value, not just a single example.
