the purpose of Just in Time (JIT) and Just in Case (JIC) inventory management

4.2 Inventory Management – Just in Time (JIT) & Just in Case (JIC)

What is JIT? 📦

Just in Time (JIT) is an inventory strategy that aims to keep stock levels as low as possible by receiving goods only when they are needed in the production process. Think of it like ordering a pizza only when you’re ready to eat it – no leftovers, no waste.

What is JIC? 🛠️

Just in Case (JIC) is the opposite approach. Companies keep larger safety stocks to protect against uncertainty such as supply delays or sudden demand spikes. It’s like keeping a spare pizza in the fridge just in case you’re hungry later.

Why Use JIT? ⏱️

  • Reduces storage costs – less warehouse space needed.
  • Minimises waste – products are produced closer to sale.
  • Improves cash flow – money isn’t tied up in inventory.
  • Encourages close supplier relationships – frequent, small orders.

Why Use JIC? 📈

  • Protects against supply chain disruptions.
  • Ensures product availability during demand spikes.
  • Reduces risk of stockouts and lost sales.
  • Useful for products with long lead times or high variability.

Real‑World Example

JIT Example: A smartphone manufacturer receives components from suppliers just before assembly. If a supplier delays, the production line stops, but the company saves on storage costs.

JIC Example: A grocery store keeps a large stock of canned goods to survive a sudden supply disruption. The extra inventory ensures customers can still buy their favourite items.
