Step-by-step explanation:
Out of the four supply chain functions mentioned, Transportation should be focused on customer service because of its timely delivering of products to consumers.
Transportation plays a crucial role in ensuring that products reach customers on time. It involves the movement of goods from one location to another, whether by road, rail, air, or sea.
For example, if a company relies on efficient transportation networks, it can deliver products more quickly to its customers, increasing customer satisfaction and loyalty. On the other hand, if transportation is inefficient, delays may occur, negatively impacting customer service and the company's reputation.
