Supply Chains
Supply chains are the networks of organizations, people, activities, and resources involved in delivering products or services from production to consumption. They encompass procurement of raw materials, manufacturing, logistics, distribution, and retail, often spanning multiple countries and involving complex coordination between suppliers, manufacturers, and retailers. Modern supply chains have become increasingly globalized over the past several decades, with companies sourcing components and labor from wherever costs are lowest, a strategy enabled by advances in transportation, communications, and international trade agreements.
Structure and Function
A typical supply chain begins with raw material extraction or sourcing, moves through manufacturing and assembly processes, and continues through warehousing, transportation, and retail distribution to end consumers. Each stage involves different actors—from miners and farmers to factories, logistics companies, and retail outlets—who must coordinate production schedules, inventory levels, and delivery timelines. Information systems increasingly track products throughout these stages, allowing companies to manage costs and respond to demand fluctuations.
Global Characteristics and Trade-offs
The shift toward global supply chains has reduced consumer prices and increased product availability by allowing companies to concentrate manufacturing in regions with lower labor costs and favorable regulatory environments. However, this globalization creates dependencies on distant suppliers, extends delivery times, and can obscure working conditions and environmental impacts throughout the production process. Supply chain disruptions—from natural disasters to geopolitical tensions to pandemics—can cascade through entire industries, affecting product availability and prices worldwide.
