What Is Kanban Scheduling?
What are the benefits of Kanban scheduling?
Kanban’s core philosophy focuses on establishing a stable production flow that is based on customer demand.
Therefore, production work takes place only when a customer demand request comes in. Such a production scheduling system has many benefits including:
What are the different kinds of Kanban scheduling systems?
Here are the most widely used Kanban systems:
- Production Kanban - In this Kanban system, any sold or consumed items are replaced with new ones.
- Withdrawal Kanban - Items are moved or relocated from one work process or place to another in a withdrawal Kanban.
- Signal Kanban - Signal Kanban is a system that triggers replenishment or production of a specific product with a pre-defined batch size.
How does Kanban scheduling work?
Kanban scheduling has a systematic approach to work that can be better understood with a simple example. Here’s a sample Kanban scheduling system that a supermarket may have.
- Supermarket stores hundreds of defined inventory items in different locations
- A customer selects specific items and goes to the checkout counter to purchase them
- The cashier scans the items and emits signals or ‘Kanban’ to the inventory database that the chosen items have been consumed and are no longer in stock
- Now supermarket employees can refill the stock after specified quantities of supplies are depleted
When is Kanban scheduling useful?
Though Kanban methodology is a holistic concept that can be applied across disciplines, it is beneficial for certain situations:
- When consumption demand is relatively stable or predictable
- Time to replenish stocks is clear and can be predicted
- Custom production is required where lot sizes can be different across orders
