Toyota Motor Corporation created a production system that aims to achieve high-quality products, minimize expenses, and shorten the time it takes to make them by reducing waste. TPS consists of two main components, just-in-time and jidoka, and is usually represented by the "house" image shown on the right. To make TPS better and keep it working well, we follow a process called PDCA or the scientific method. We do this by repeatedly doing standardized work and making small improvements called kaizen.
