Inventory Management: Just In Time (Jit) (Copy)
4.2.2 Just In Time (JIT)
The Purpose Of JIT And JIC (Just In Case) Inventory Management
- Just In Time (JIT)
- Definition: An inventory management system where materials and components are ordered and received only when needed in the production process, minimising stock levels.
- Purpose:
- Reduce costs of holding inventory.
- Eliminate waste from overproduction and excess stock.
- Encourage efficiency and discipline in supply chain operations.
- Example: Toyota pioneered JIT by synchronising supplier deliveries directly with production schedules.
- Just In Case (JIC)
- Definition: A contrasting inventory approach where businesses hold buffer or safety stock to protect against uncertainty in demand or supply.
- Purpose:
- Reduce risk of stockouts and production stoppages.
- Ensure customer orders can be met during unexpected demand surges or supply delays.
- Example: Supermarkets keeping extra stock of essential goods before public holidays.

The Impact Of Adopting A JIT Approach On A Business
- Advantages Of JIT
- Lower Storage Costs: Less need for warehouses, reducing rent, utilities, and insurance.
- Reduced Waste: Lower risk of inventory obsolescence or spoilage, especially important for perishable goods.
- Improved Cash Flow: Capital is not tied up in stock; funds available for investment elsewhere.
- Greater Efficiency: Encourages streamlined production processes and close supplier relationships.
- Higher Quality Control: Smaller batches delivered more frequently make it easier to identify defects early.
- Environmental Benefits: Less waste and reduced storage requirements improve sustainability.
- Example: Dell uses JIT to assemble customised laptops only when orders are placed, keeping costs low.

- Disadvantages Of JIT
- Supply Chain Vulnerability: Any delay from suppliers halts production.
- High Dependence On Reliability: Requires strong, trustworthy relationships with suppliers.
- Increased Transport Costs: Frequent smaller deliveries may be more expensive.
- No Safety Net: Unexpected demand surges or supply disruptions can cause stockouts.
- Risk During Global Crises: Pandemics, natural disasters, or political instability disrupt JIT systems.
- Example: Automotive companies faced shortages of microchips during COVID-19 because of reliance on JIT.

Strategic Considerations Of JIT vs JIC
- When JIT Is Suitable
- Stable demand patterns.
- Reliable and local suppliers.
- Industries where storage costs are high or goods are perishable.
- Businesses seeking lean, cost-efficient operations.
- When JIC Is Suitable
- Uncertain or seasonal demand.
- High risk of supply chain disruption.
- Markets where product availability is critical to customer loyalty.
- Example: Pharmaceutical companies often prefer JIC for essential medicines.

Strategic Impact Of JIT Adoption
- Businesses adopting JIT must invest in supply chain integration, IT systems, and strong supplier partnerships.
- JIT reduces costs but increases risk exposure → firms may combine JIT with limited JIC to balance efficiency and security.
- Example: Toyota operates JIT but still maintains minimal buffer stock for critical components.
- Long-term sustainability requires resilience planning, as JIT alone may not withstand global disruptions.
