Reclaiming Toyota Production System: My Lean TPS Basic Thinking

TPS Basic Thinking continues the tradition of Toyota Production System learning, emphasizing reflection, abnormality response, and waste elimination through structured training.

Reflection, or Hansei, is a central habit in the Toyota Production System. It reminds us to pause, study our progress, and build on what has been learned. My Lean TPS Basic Thinking represents that same practice of reflection, drawn from my early years implementing TPS at Toyota BT Raymond in Canada.

During this period, I developed a customized TPS Basic Training Program to help teams understand and apply the principles of Just In Time, Jidoka, and Standardized Work. These materials were not academic. They were designed for use on the shop floor where real learning happens. When Mr. Sadao Nomura, Senior Advisor at Toyota Industries Corporation, visited our facility, he reviewed these modules in detail. His response was simple but meaningful: “TPS training ongoing very good progress. Thank you.” That note became part of his Nomura Memo No. 31, dated January 2007.

This validation from one of Toyota’s leading quality experts reinforced a key truth: practical TPS training must always focus on implementation, not presentation. Mr. Nomura emphasized the need to accelerate improvement because of excessive muda, or waste, in daily operations. His direction was clear: start at the shop floor, find the critical areas first, and work through the process with your own eyes.

As TPS Coordinator, Kaizen Manager, and later Jishuken Core Member with Toyota Material Handling Manufacturing North America, I applied these principles every day. Working alongside mentors like Mr. Nomura, Mr. Seiji Sakata, and Mr. Susumu “Sonny” Toyoda, I learned that the strength of TPS is not in its tools but in the thinking of its people. The structure of Standardized Work, the discipline of stopping for abnormality, and the rhythm of Heijunka all exist to develop people who can see and solve problems.

Lean TPS Basic Thinking continues that legacy. It teaches how to connect purpose, process, and people through structured learning. Each module builds the capability to identify abnormality, reduce stagnation, and sustain flow. The goal is not to copy Toyota, but to understand how the Toyota Production System was designed to prevent failure by teaching people to think.

The message from Mr. Nomura still applies today. There is always muda to eliminate and always progress to make. Continuous improvement begins with seeing clearly, thinking deeply, and acting immediately. That is the purpose of Lean TPS Basic Thinking.

This Lean TPS Basic Training visual explains how Kaizen operates within the governed architecture of the Toyota Production System. Just In Time and Jidoka function as structural pillars, Heijunka and Standardized Work provide stability, and Kaizen strengthens the system only when standards and control are in place.

Theory of Constraints manages conflict after instability forms. Lean TPS prevents conflict through governance of demand, capacity, and Quality before execution begins.

Dashboards and scorecards increase visibility, but they do not govern work. In Lean TPS, Andon exists to control abnormality in real time by enforcing stop authority, response timing, and leadership obligation to protect Quality.
Lean TPS Disruptive SWOT transforms traditional SWOT from a static listing exercise into a governed leadership system. Through Survey, Prioritize, and Action, it aligns strategic direction with Quality, system stability, and explicit leadership obligation within a Lean TPS governance framework.

In Lean TPS, Respect for People and Continuous Improvement are not independent goals. Both emerge from Quality governance, where leaders define normal work, make abnormality visible, and respond to protect system stability.

5S Thinking is not about making the workplace look clean or impressive. In Lean TPS, it functions as a visual reset that restores the ability to see normal versus abnormal conditions. When the environment is stabilized, problems surface quickly, Quality risks are exposed earlier, and problem solving becomes possible at
