Supply chain demand is the amount of goods and services that customers desire from a business or industry. It is commonly used to measure how well companies meet customer needs, identify gaps in their supply chain processes, and adjust operations accordingly. At its core, supply chain demand reflects the total amounts of products, technologies, services, and solutions required by customers. By taking into account customer requirements and forecasting potential changes in demand, businesses have better insight into what they need to produce, store, and deliver to stay competitive.
