Which statement best defines value-added work in a lean system?

• A. Activities that must be performed under present work conditions
• B. Eliminating all defects and the need for rework
• C. Changing the shape or character of a product or assembly
• D. Activities that do not alter the product or assembly

Answer: (C)

Value-added work is the part of the process that actually changes the product or service in a way the customer is willing to pay for. The statement that describes changing the shape or character of a product or assembly fits this idea best because it specifies a transformation that moves the item toward its final form, which is what customers value. In lean thinking, activities that don’t alter the product don’t add value, since they don’t change the form, fit, or function the customer will pay for. Eliminating defects and rework are important for quality and efficiency, but the act of rework itself is not value-added because it corrects something that shouldn’t have needed changing in the first place. Doing work under current conditions doesn’t define whether the activity adds value either.
