Toyota Production SystemToyota Production SystemDimitri Ponomareff2022-08-15T18:18:40-07:00 Toyota Production System (TPS), originally called “Just-in-Time production”, was developed by Toyota to organize their manufacturing operations including logistics, supplier management, up to customer delivery. Its basic concept is the reduction of cost through elimination of waste and optimization of machine and human capabilities. Prior to TPS, problems such as imbalanced inventory levels coupled with surplus equipment and workers were experienced by the automobile giant. Toyota decided to put its efforts in the development of a production system that can shorten the time between the initiation and completion of a production process, namely from the entry of materials to the completion of the vehicle. In this type of production, only the necessary products, at the necessary time, in necessary quantities are manufactured. This way the stock on-hand is held down to a minimum. Equally important, Toyota has built up a system of respect for people ingrained in the TPS concept. It puts emphasis on the points as follows:
Apart from the JIT concept, another essential feature of the TPS is Jidoka. The term Jidoka means to make the equipment or operation stop whenever an abnormal or defective condition arises. In short, its distinctive feature lies in the fact that when an equipment problem or machine defect happens, the equipment or entire line stops, and any line with workers can be stopped by them. Just-in-Time and Jidoka are the main pillars of the Toyota Production System. The main objectives of the TPS are to design out overload and inconsistency and to eliminate waste. The most significant effects on process value delivery are achieved by designing a process capable of delivering the required results smoothly, by minimizing inconsistency. It is also crucial to ensure that the process is as flexible as necessary without stress or overburden since this generates waste (e.g. waste of overproduction, waste of transportation, waste of making defective products etc.). A production control system for just-in-time production and making full use of workers’ capabilities is the Kanban System. In Kanban, the supply of parts or components is regulated on cards that contain very clear specifications and instructions. These cards move systematically forward along a production line. Kanban became an effective tool to support managing a production system as a whole, and an excellent way to promote improvement. Problem areas are highlighted by measuring the time between the initiation and completion of a full production process. This sign-based scheduling system was developed to eliminate waste and improve production efficiency, but can be applied to just about any industry, process or task. Toyota has six rules for the effective application of Kanban:
Apart from Kanban, there are ten more conceptual pillars that make up the Toyota Production System philosophy. These pillars further support the Just-in-Time and Jidoka (autonomation) goals of the TPS and complete the thirteen pillars of the Toyota Production System.
The Toyota Production System became the foundation of Lean thinking and production. An extensive study led by researchers from the Massachusetts Institute of Technology in the 1990s titled, The Machine that Changed the World, expounded the results of this then novel approach and pushed it to global recognition. Today, we see Lean being used across industries outside of manufacturing and enabling sustainable businesses over the years.

Without Kaizen, the Toyota Production System would have no foundation. The principle behind Kaizen is to always be improving.
What is the Toyota production model?The way we make vehicles is defined by the Toyota Production System (TPS). It is an original manufacturing philosophy that aims to eliminate waste and achieve the best possible efficiency – what is often called a “lean” or “Just-In-Time” system.
What makes the Toyota Production System successful?While having low inventory levels is certainly a key component to the Toyota Production System, just as important are the simple and low-tech fundamental pillars of the system — strict adherence to procedures, constant improvement (called “kaizen”), getting to the root of problems and respect for line workers.
How does Toyota implement continuous improvement?The Toyota Way management approach is an integral part of the continuous improvement Toyota Production System. Toyota has gone to extraordinary lengths to remove every roadblock to production leveling, especially in reducing changeover times so that it can support various production lines without production loss.
