Explanation:

JIT stands for Just in time management. It is an inventory management approach that advocates for the purchase of materials just when they are needed for production. In JIT, there is no storing of materials for use for future production. The purchase of materials is aligned with the production process.

The success of JIT is dependent on management ability to forecast sales volumes accurately. Management must work with reliable suppliers to ensure that materials are available when required. JIT lower's the cost of inventory management by eliminating the need to store huge quantities of materials. It reduces wastage by doing away with losses that arise due to the storage of bulk materials.
