In a supply chain, how do information and products flow?

In a supply chain, information and products flow in both upstream and downstream directions, which is why this answer is correct.

The downstream flow refers to the movement of products and information from suppliers to consumers. This includes the distribution of finished goods and relevant data concerning inventory levels, sales, and market trends to retailers and customers.

Conversely, the upstream flow involves the movement of information and materials from consumers back to suppliers. For instance, customer feedback, demand signals, and product returns provide essential insights that influence inventory management and production decisions.

The dual flow of both products and information is crucial for maintaining effective communication and responsiveness throughout the supply chain. It enables businesses to adjust their strategies based on real-time data, optimize inventory levels, and enhance customer satisfaction. The integrated movement reinforces collaboration among different stakeholders, making the entire supply chain more agile and efficient.
