,Unit 2 Manufacturing Competitiveness and Improvement
1) Lean manufacturing focuses on reducing costs that do not create value for the customer.
Answer: TRUE
Explanation: Correct! Lean manufacturing aims to reduce or eliminate costs that do not create
value for the customer.
2) Overproduction is beneficial as it ensures that products are always available to meet customer
demand.
Answer: FALSE
Explanation: Correct! Overproduction often hides real problems and opportunities for
improvement in manufacturing.
3) Unnecessary motion by people or equipment is considered waste in lean manufacturing.
Answer: TRUE
Explanation: Correct! Unnecessary motion is related to ergonomics and is seen in all
unnecessary movement of people performing an operation or a task.
