Supply Chain Management is a cross-functional method to control the transfer of raw materials into and completed items out of a business to the end consumer.To understand the tasks necessary to control material mobility across organisational and functional boundaries, several models have been presented. The supply chain council promotes Supply Chain Operations References (SCOR), a supply chain management approach. The Global Supply Chain Forum has proposed a paradigm called Supply Chain Management (GSCF). Activities in the supply chain may be divided into three categories: strategic, tactical, and operational. The development and execution of a long-term supply chain plan is the foundation of a company's Supply Chain Management activities. 

This plan should include, among other things:

(a) Determine which supply chains the company wants to compete in.

(b) Assist managers in understanding how the company will provide value to the supply chain.

(c) Assist in the selection of supply chain partners such as suppliers, subcontractors, transportation companies, and distributors. When companies are preparing to comprehend the supply networks in which they compete, it's helpful to map the physical and information flows that make up such supply chains. Firms may begin to understand how they offer value. The firm's supply chain strategy, of course, doesn't exist in a vacuum. It must be in line with the company's overall strategy as well as efforts in areas like buying, logistics, production, and marketing.
