Global sourcing and supply chain management in procurement is the practice of strategically investing resources in external global suppliers to gain access to high-quality goods and services while improving overall cost-efficiency. It is a complex system that involves managing the flow of raw materials and parts, as well as inventory, production, and finished products in order to ensure the most efficient and effective delivery of goods and services at the best cost possible. This requires agility with constantly changing conditions such as fluctuating international markets and regulations, customer preferences, and technological advances that must be quickly adapted to maximize efficiency. Global sourcing and supply chain management in procurement can give businesses a competitive edge in a complex and often unpredictable environment.
