Taiichi Ohno: inventor of kanban
In the mid-20th century, Taiichi Ohno (*1912 †1990) developed the basic logistics concepts of the "pull principle", "just-in-time" and "kanban", successfully implementing these concepts at Japanese car maker Toyota. In recognition of these achievements, the Japanese pioneer was inducted into the Logistics Hall of Fame in 2004.

- Ohno is considered the father of the "Toyota Production System", which revolutionised worldwide automotive production in the 70s and 80s and is still a model for the production lines of automotive manufacturers today. In the 80s, many Western managers made the pilgrimage to see Ohno's work in Japan.
- The "just-in-time concept" is seen as one of the two pillars of this system: the individual materials should only arrive at the assembly line in the right quantity, quality and order when they are actually needed.
- In order to pave the way for just-in-time deliveries to the production process, Taiichi Ohno developed the "kanban" principle, which is still used in production processes. Using the kanban card, the upstream process steps are requested by the downstream process step to produce the parts specified on the card and to deliver these parts to a predetermined location on a specific date. A production run may not be initiated without a kanban card. The kanban system, which today is often supported by barcode and IT systems, is the standard in many German industrial companies.
- The basic idea behind the just-in-time concept is the change from the push principle to the pull principle. Ohno was the first person to view the production process as beginning with the "customer". Each downstream production step is the customer of the upstream process step. Goods are requested by the customer based on demand (pull) and not simply produced by the upstream production process and sent to the customer (push). This changeover from push to pull is still right at the top of agenda in much of the recent specialist logistics literature.
