Learn about our Editorial Process Updated on 02/26/21 A supply chain is comprised of all the businesses and individual contributors involved in creating a product, from raw materials to finished merchandise. Logistics is a specialized field of its own comprised of shipping, warehousing, courier services, road/rail transportation, and air freight. Retail companies become involved in supply chain management to control product quality, inventory levels, timing, and expenses. In a global economy, supply chain management often includes dealings with companies and individual contributors in other countries, which requires involvement in politics, trade and tariff laws, quality control, and international relationships. Examples of supply chain activities include farming, refining, design, manufacturing, packaging, and transportation. Because global supply chains are both logistically and technologically complicated, there are now global supply chain management specialists and firms who oversee the process for many different retail companies.
