A global supply chain refers to the interconnected network of organizations, individuals, resources, and activities involved in the production, distribution, and delivery of goods and services across multiple countries and continents.

At a high level, the global supply chain can be broken down into several key components, including sourcing of raw materials, manufacturing, transportation and logistics, and distribution to end customers. Each of these components involves a complex network of suppliers, vendors, manufacturers, distributors, and other stakeholders, many of whom are located in different parts of the world.
