Produktionskanban

Produktionskanban is a visual scheduling method originating from the Toyota Production System. It was developed in the 1940s and 1950s as part of Japan’s post‑war industrial reorganization and introduced to Western manufacturers in the 1980s through the work of Dr. Taiichi Ohno and the Lean methodology movement.

The core principle of a Produktionskanban system is pull production: items are produced only when a downstream process demands them. This is achieved through physical or digital cards, often called kanban cards, that move through a production line or among workstations. When a bin or component is emptied, a card signals the preceding station to replenish the stock. There are typically two main types of kanbans: signal kanbans, which trigger replenishment, and replenishment kanbans, which carry information such as quantities, schedules, and tracking data.

Implementing a Produktionskanban system requires a clear definition of process steps, the establishment of kanban boards or shelves, and training of operators to respond to card signals. The method is especially effective in environments with high variability in demand, limited space, or a need for rapid response to customer orders.

Benefits include reduced inventory levels, lower waste, improved lead times, and greater transparency across the supply chain. Potential limitations involve the initial setup cost, the requirement for disciplined adherence, and the risk of system breakdown if cards are lost or mis‑used. Many modern manufacturers integrate Produktionskanban with digital platforms such as MES (Manufacturing Execution Systems) or ERP systems to leverage real‑time data analytics and automate the card issuance process.
