1) Just in Time (JIT) is a modern manufacturing model that companies use to maximize revenue, profit, and sales while minimizing overhead and inventory costs. 2) Under JIT, companies produce products according to customer demand rather than for stock, creating a win-win situation for all involved in the business from suppliers to customers. 3) Examples of companies using JIT are Amazon and Maserati, as JIT takes advantage of today's ability to instantly access, process, receive, and send information anywhere in the world.
