Certified Maintenance & Reliability Professional (CMRP) Practice Exam

Which of the following activities is classified as "motion" waste?

1. People waiting for materials

2. Excess transportation of goods

3. Equipment moving more than necessary

4. Overproduction of items

The correct answer is: Equipment moving more than necessary

Motion waste refers specifically to unnecessary movements of people or equipment that do not add value to a process. In this context, the correct focus is on equipment movements. When equipment moves more than necessary, it indicates inefficiencies in operations and can lead to increased wear and tear, higher operating costs, and reduced production efficiency. Reducing unnecessary motion can streamline processes, minimize downtime, and enhance overall productivity. The other activities mentioned—such as people waiting for materials, excess transportation of goods, and overproduction—while certainly representing forms of waste in their respective categories (waiting waste, transportation waste, and overproduction waste), do not specifically pertain to the motions of equipment or individuals in a manner that strictly defines motion waste.
