Final answer:
Moving components to a warehouse for storage until the factory needs them is an example of an operation that does not add value.
Step-by-step explanation:
An example of an operation that does not add value is moving components to a warehouse for storage until the factory needs them.
This operation does not add value because it does not directly contribute to the final product or improve its quality. Instead, it adds additional time and costs to the manufacturing process.
In contrast, operations like filling the underground gasoline tanks at a service station, removing iron ore from the ground and shipping it to a steel mill, and making a wedding cake all add value by directly contributing to the final product or service.
