Kanban in Operations Management
In operations management, Kanban links customer demand to production, inventory, fulfilment and maintenance through simple pull signals. Learn how a Kanban system works in operations, what it costs and saves, and how to start.
Quick answer: In operations management, Kanban is a pull-based control system: when stock or capacity is used, a card, bin or electronic signal triggers replenishment of exactly that amount. It controls production and inventory, keeps work in progress low and makes problems visible. Kanban costing shows the inventory value held in each loop.
1. Key Takeaways
- Kanban in operations management controls production and inventory by pull.
- Each loop: demand → signal → replenish → deliver.
- Number of kanbans = demand × lead time × (1 + safety) ÷ container size.
- Kanban costing: cards × container qty × unit cost = money in the loop.
- Fewer cards free working capital – step by step.
2. Where Kanban Fits in Operations Management
Kanban is used across operations: production control, inventory, order fulfilment, maintenance and supplier management.
3. How a Kanban System Works in Operations
Consumption sends a signal, the signal triggers replenishment of exactly what was used, and the loop repeats.
4. Kanban Costing
Kanban costing makes the money tied up in each loop visible and shows the savings from lower inventory, less expediting and no overproduction.

6. Implementing Kanban in Production and Operations
Pick one value stream, map flow and stock, size the loops, train the team, measure and then remove cards.
