Final answer:
Motion is the element of waste that best describes the unnecessary movement of materials and goods.
Step-by-step explanation:
The element of waste that best describes "the unnecessary movement of materials and/or goods" is Motion. Motion waste refers to any movement that does not add value to the product or service being produced. In a business context, this could include excessive handling, transportation, or repositioning of materials or goods.
For example, in a manufacturing setting, if workers have to repeatedly walk long distances to access tools or materials, it creates unnecessary motion waste. This waste can be eliminated or minimized by organizing workstations and processes to optimize efficiency.
