Here is the text from "Supply Chain Management" by Sunil Chopra, 7th Edition:

The term supply chain management (SCM) was first used in the 1980s. Since then, it has become a widely accepted term in the business world. SCM refers to the coordination and management of activities involved in the supply chain. The goal of SCM is to provide a seamless flow of goods, services, and information from raw materials to end customers.

The objective of a supply chain is to provide value to the customer. This value can be in the form of a product or a service. The parties in a supply chain work together to create this value. Effective management of the supply chain can provide a competitive advantage to a company.
