JIT, or Just-in-Time, is an inventory and production management system that has revolutionized the way businesses operate. It works by requiring goods to be available “just in time” for when they are required, thus eliminating excess inventory which could become outdated and unusable. JIT allows businesses to stay competitive by reducing costs associated with holding large amounts of inventory. It also reduces the risk of manufacturing defects, since manufacturers can directly supply their goods to customers as needed. With JIT, businesses can rely on suppliers to deliver goods quickly and efficiently, allowing them to focus on demand forecasting and customer service.
