Advantages and Disadvantages of Just-In-Time Inventory
Unfortunately, this approach has a number of major drawbacks including large inventories, long production times, high defect rates, production obsolescence, inability to meet delivery schedules, and ironically high costs. None of this is obvious -if it were, companies would long ago have abandoned this approach. JIT is a production and inventory control system in which materials are purchased and units are produced only as needed to meet actual customer demand.
In just in time manufacturing system inventories are reduced to the minimum and in some cases they are zero. JIT works in the three types of inventories: a Raw materials: inventories provide insurance in case suppliers are late with deliveries. Funds that were tied up in inventories can be used elsewhere.
Areas previously used to store inventories can be used for other more productive uses. Throughput time is reduced, resulting in greater potential output and quicker response to customers. Defect rates are reduced, resulting in less waste and greater customer satisfaction. Most companies find, however, that simply reducing inventories is not enough.
To remain competitive in an ever changing and ever competitive business environment, must strive for continuous improvement. While machines from Compaq and IBM can languish on dealer shelves for two months Dell does not start ordering components and assembling computers until an order is booked. By ordering right before assembly, Dell figures it s parts, on average, are 60 days newer than those in an IBM or Compaq machine. JIT manufacturing also opens businesses to a number of risks, notably those associated with the supply chain.
With no stocks to fall back on, a minor disruption in supplies to the business from just one supplier could force production to cease at very short notice. A real business example: Toyota Just-in-time manufacturing system is vulnerable to unexpected disruptions in supply chain.
A production line can quickly come to a halt if essential parts are unavailable. Toyota, the developer of JIT, found this out the hard way. By Tuesday, Toyota had to close down all of its Japanese assembly line.

Just-in-time inventory management works by keeping stock levels low; you order just what you need, as closely as possible to when you need it. This approach to inventory management is an essential element in the philosophy of lean manufacturing, which is based on using information and strategy to run a business as efficiently as possible. Just-in-time inventory helps you to manage cash flow. When you stock up and buy inventory in bulk, you may get better prices, but you're likely to buy more than you need for your present purposes. Your working capital will then be tied up in materials that just sit on the shelf for the foreseeable future and you may not have the cash you need for day-to-day expenses such as rent and payroll. Just-in-time inventory reduces the clutter that is an inevitable result of keeping too much stock on hand. With reduced clutter, you'll have space to operate more efficiently.

Long before eCommerce or inventory management software, businesses attempted to meet consumer demand by manufacturing surplus quantities of products and stockpiling inventory. They manufactured just enough inventory to satisfy anticipated demand or they heavily relied on their sales and marketing teams to generate more demand to sell the overstocked inventory.
