Just-In-Time (JIT) Inventory

just-in-time (jit) inventory

Just-In-Time (JIT) Inventory is a production strategy that aims to improve a business’s return on investment by reducing in-process inventory and its associated carrying costs.

JIT Inventory involves producing goods to meet demand rather than creating surplus stock. This approach requires accurate forecasting and fast, responsive supply chains.

Implementing JIT inventory involves a commitment to monitoring supply and demand closely. Businesses should also work closely with suppliers to ensure they’re reliable and can turn around orders quickly.


The Just-In-Time (JIT) Inventory process involves several steps:

  1. Customer Order: The process begins with an order from a customer.
  2. Triggering Production: The customer order triggers the production process. At this stage, only the necessary parts are ordered from suppliers.
  3. Assembly: The ordered parts are quickly assembled into the final product.
  4. Minimising Waste and Increasing Efficiency: Because inventory is purchased and produced only as needed, waste is minimised, efficiency is increased, and the cost of storing excess inventory is reduced.
  5. Dependence on Forecasting and Responsiveness: The success of this process heavily relies on accurate demand forecasting and a highly responsive supply chain.

Pros and Cons of JIT Inventory


  1. Reduced Inventory Costs: Since JIT involves keeping minimal stock, businesses can save on storage and insurance costs.
  2. Improved Cash Flow: Money that would have been tied up in inventory can be used elsewhere within the business.
  3. Less Waste: If there’s a problem with a product, fewer items will need to be discarded or fixed.


  1. Requires Accurate Forecasting: Inaccurate sales forecasts could lead to stockouts, leading to lost sales.
  2. Reliant on Suppliers: JIT requires suppliers to be reliable, as any delays can disrupt the entire production process.
