The Just-In-Time (JIT) inventory system is a strategy used in supply chain management to increase efficiency and decrease waste by receiving goods only as they are needed in the production process. The main objective of JIT is to minimize inventory levels and associated carrying costs, such as storage, insurance, and obsolescence costs. By ordering inventory only as it is needed, companies can reduce the amount of capital tied up in inventory and improve cash flow.

**_ Increasing stock levels is contrary to the principles of JIT. JIT aims to reduce inventory levels to the minimum necessary, not increase them. Maintaining a permanent stock implies keeping a consistent level of inventory at all times. This is opposite to JIT, which focuses on reducing inventory and ordering only what is needed, when it is needed. Ordering seasonal products in advance is a strategy used for managing seasonal demand, not for reducing inventory levels. JIT focuses on minimizing inventory by ordering based on immediate needs rather than forecasting future demands. The JIT inventory system is designed to decrease stock levels and reduce carrying costs by ordering inventory only as needed. This approach contrasts with strategies that involve increasing stock levels, maintaining permanent stock, or ordering in advance for seasonal demand.
