For many companies, this emphasis on timing helps them keep and increase their market presence. JIT inventory management requires everyone in an ecosystem and supply chain to commit and work cohesively. If any part of that arrangement breaks down, it risks the entire infrastructure.

Imagine what your business can achieve by cutting down on this zero-value task. The success of JIT also requires high-quality workmanship, reliable suppliers, and consistently error-free machinery. In a JIT system, companies keep on hand only materials that will be immediately used for the production of goods.

Stock-outs and shortages may cause havoc with inventory management systems.

Furthermore, a thoroughly implemented JIT system should shorten the amount of time required to manufacture products, which may decrease the quoted lead times given to customers placing orders. JIT inventory management is a methodology that aims to minimize inventory levels for the production process by taking in goods or components only when needed, resulting in significant cost benefits.

The JIT system aided Toyota in becoming one of the most dominant car manufacturers in the world by achieving lean manufacturing. Lean manufacturing refers to the process of eliminating waste in the production process by identifying what adds value and what doesn’t add value. Just in Time can also be defined as “a philosophy of manufacturing based on planned elimination of all waste and on continuous improvement of productivity”.

When the COGS is deducted from the sales revenue, it reveals the operational efficiency of the business. It also gives us an idea about the bottom line since COGS is considered a business expense. Mathematically, it is equal to the starting inventory + purchases during the production cycle – closing inventory. The procurement, management, and storage of extra raw materials and inventories are all reduced under the JIT approach.

Reducing overproduction: JIT helps to eliminate overproduction, which is one of the main causes of waste in the manufacturing process. By producing only what is needed, JIT reduces the amount of excess inventory that is produced, which can lead to waste in the form of storage costs, obsolescence, and damage.

For starters, keeping less inventory on hand gives you more freedom when it comes to your cash flow. Instead of spending all your revenue from the past month on a massive replenishment order, you can allocate a small portion of your earnings for inventory.
