Just-in-time (JIT) systems enable business operations to maximize efficiency, reduce costs, and improve customer service by providing timely delivery of goods and services when they are needed. JIT systems use lean principles to streamline the production process and eliminate wasteful activities such as overproduction, excess inventory, waiting times, and motion. By only producing what is needed at the right time and in the right place, JIT systems help businesses operate more efficiently while reducing their overall costs. With shorter lead times, JIT systems also allow businesses to better meet customer needs, become more competitive in the market, and increase their revenue.
