Final answer:
The timing of when a product is manufactured can influence its value-added.
Step-by-step explanation:
The timing of when a product is manufactured can indeed influence its value-added. While it is true that having a product ready in advance of customer demand is beneficial, the timing of manufacturing can still impact the value-added. For example, if a product is manufactured too early and sits in inventory for a long time, it may become outdated or lose value. On the other hand, manufacturing a product too close to customer demand may result in higher costs or delays in delivery.
