The Toyota Production System (TPS) (トヨタ生産方式) is the
framework and and the interaction of these facilities with the suppliers and
customers. The main goal of the TPS is to eliminate waste (無駄, muda).
There are 4 kinds of waste found in the TPS:
- Excessive Production Resources
- Excessive Facilities
- Excessive Workforce
- Overproduction
- Excessive Inventory
- Unnecessary Capital Investments
Toyota was able to greatly reduce cost and inventory using the TPS,
enabling it to become one of the three largest companies in the world. Due
to this stellar success of the production philosophy many of these methods
have been copied by other manufacturing companies.
