Just in Time (JIT) is a strategy where a company keeps very little stock on hand and orders new supplies only when they are needed for production or sale. Think of it like a chef who buys fresh ingredients right before cooking, instead of keeping a huge pantry full of food that might spoil.
JIT changes how a business plans production, manages suppliers, and monitors inventory levels. The key equation for cost comparison is:
\$\$
C{\text{total}} = C{\text{inventory}} + C_{\text{stockouts}}
\$\$
where \(C{\text{inventory}}\) is the cost of holding stock and \(C{\text{stockouts}}\) is the cost of running out of items. A well‑implemented JIT system aims to minimise both terms, but if supply fails, \(C_{\text{stockouts}}\) can rise sharply.
| Aspect | Benefit | Risk |
|---|---|---|
| Inventory Levels | ↓ Holding costs | ↑ Stockouts if demand spikes |
| Supplier Relations | Closer collaboration, better terms | Dependence on supplier reliability |
| Production Planning | More flexible, responsive to demand | Requires accurate forecasting |
