Key Principles of Toyota Production System


The global economy has witnessed unprecedented disruptions in the past few years, emphasising the need for robust production systems. The Toyota Production System (TPS) has undergone continuous refinement and adaptation to meet the automotive industry’s changing needs. 

Toyota’s relentless pursuit of efficiency, quality, and customer satisfaction has enabled them to weather numerous disruptions and set industry standards. By implementing TPS, the automobile company has successfully minimised waste, optimised production processes, and established a culture of continuous improvement.

What is the Toyota Production System?

Taiichi Ohno and Eiji Toyoda developed TPS between 1948 and 1975, which later became the foundation for lean manufacturing. TPS is a comprehensive management system that includes manufacturing, logistics, and the entire ecosystem of interactions with suppliers and customers. 

It is built upon the philosophy of completely eliminating waste in pursuit of the most efficient methods. TPS Lean and its approach to cost reduction serve as the wellsprings of competitive strength and unique advantages for Toyota.

The core objective of lean manufacturing and its general principles is to eliminate anything that does not add value from the customer’s perspective. With proper lean training in Australia, organisations can enhance productivity, create more significant customer value, and optimise resource utilisation, successfully implementing a lean TPS.

Main Principles of the Toyota Production System

  • Just-in-Time (JIT) Production

JIT principles enable companies to produce goods or deliver services precisely when and where needed. By minimising inventory, reducing lead times, and synchronising production with customer demand, JIT enhances operational efficiency, lowers costs, and improves responsiveness.

  • Continuous Improvement (Kaizen)

The concept of Kaizen drives the philosophy of continuous improvement within TPS. It empowers employees at all levels to identify and implement small, incremental changes that enhance processes, eradicate waste, and drive innovation. 

Through the culture of Kaizen, companies can achieve sustainable growth and maintain a competitive advantage.

  • Respect for People 

TPS recognises that any organisation’s success depends on its employees’ skills, knowledge, and creativity. The workforce produces unmatchable results only when the work culture revolves around mutual respect, trust, and empowerment. Such a place will automatically lead to higher productivity, increased engagement, and improved outcomes.

  • Standardisation and Standard Work

 Standardisation is a fundamental aspect of TPS that ensures consistent quality and performance. By establishing clear standards and work procedures, companies can reduce process variations, enhance efficiency, and provide a foundation for continuous improvement efforts.

  • Built-in Quality

TPS emphasises the importance of quality throughout the production process. By incorporating quality checks, error-proofing mechanisms, and focusing on prevention rather than detection, companies can avoid defects, reduce rework, and improve customer satisfaction.


The Toyota Production System has evolved over the years to become a globally recognised framework for operational excellence. 

With good lean training in Australia, companies will be empowered to embrace the principles of TPS, navigate disruptions, manage quality and demand/supply fluctuations, and achieve sustainable growth. Furthermore, lean training programs can help companies optimise their operations, increase competitiveness, and pave the way for long-term success in an ever-changing business landscape.
