What are the "flows" within a supply chain, and why are they important?

Supply chain management is the coordination, management and strategy that drives the flow of data, information, resources and materials to deliver the best product and service to all stakeholders in the process of converting raw goods to a salable product and delivering it to the ultimate customer.

This supply chain management flow also concerns customer returns and service needs.
