What is meant by supplies being delivered upon demand?

When supplies are delivered upon demand, it signifies a just-in-time inventory approach, where items are provided only when there is a specific requirement for them. This method helps in minimizing excess inventory, reducing storage costs, and ensuring that resources are used efficiently. By receiving supplies only as needed, organizations can respond quickly to changes in demand and avoid the overhead costs associated with holding large quantities of stock. This approach is commonly utilized in lean manufacturing and supply chain management, enhancing overall operational efficiency.
