Define the just-in-time inventory system and give one short worked example.

# Just-In-Time (JIT) Inventory System ## Definition Just-In-Time (JIT) is an inventory management strategy where materials and products arrive **exactly when needed** in the production process, minimizing inventory holding costs and waste. Companies order and receive inventory only as it's required for production or sale, rather than maintaining large stockpiles. **Key principle:** "The right material, at the right time, at the right place, in the exact amount needed." ## Worked Example **Scenario:** A bicycle manufacturer using JIT **Traditional System:** - Keeps 500 wheels in warehouse - Storage cost: $2 per wheel per month - Monthly holding cost: 500 × $2 = **$1,000/month** **JIT System:** - Produces 100 bikes per week - Orders wheels to arrive Monday morning (200 wheels) - Uses all wheels by Friday - Average inventory: ~100 wheels - Monthly holding cost: 100 × $2 = **$200/month** **Result:** - Saves $800/month in holding costs - Frees up warehouse space - Reduces waste from damaged/obsolete inventory - **Requires:** Reliable supplier and precise scheduling --- *Note: JIT requires strong supplier relationships and excellent coordination, as any delivery delay can halt production.*
