Final answer:
Value-added activities directly contribute to the final product and increase manufacturing cycle efficiency, while non-value-added activities do not add value and decrease efficiency.
Step-by-step explanation:
Value-added and non-value-added activities have a significant impact on manufacturing cycle efficiency. Value-added activities are those that directly contribute to the final product and provide value to the customer. Examples of value-added activities in manufacturing include assembly, packaging, and testing. On the other hand, non-value-added activities do not add value to the product and can include tasks such as excessive inspections, wait time, or unnecessary movement of materials. These activities increase the time and resources required to produce the final product, reducing manufacturing cycle efficiency.
