Definition: Inventory management principle where oldest products (first to arrive) are shipped/used first. Common in food and pharmaceutical cold chain.
Why It Matters:
- Prevents old product from sitting in storage while new product ships
- Reduces waste from expired products
- Standard practice in food safety
Implementation: Physical layout with “front picking” and “back stocking,” oldest product always in front.
