Toyota uses the Toyota Production System (TPS) for its operations and production management. This system was developed by the renowned industrial engineer Taiichi Ohno in the 1950s to make Toyota one of the leading car manufacturers in the world. TPS is based on the Japanese principle of Kaizen, which encourages continuous improvement. TPS focuses on creating a lean manufacturing process that minimizes waste while maintaining high quality standards. It includes techniques such as "Just-in-Time" (JIT) production, problem-solving and quality circles, standardization, and visual control. In addition, Toyota has developed a number of models and other strategies such as the Toyota Way, Total Quality Management and Value Stream Mapping to ensure that TPS is implemented successfully.
