Toyota's Production System, also known as the Toyota Way, is a set of principles and practices that have made Toyota one of the most successful and innovative car manufacturers in the world. In this article, we will take a closer look at the key elements of the Toyota Production System and explore how they can be applied to other industries to improve efficiency, quality, and customer satisfaction.
The Philosophy Behind the Toyota Production System
The foundation of the Toyota Production System is a philosophy of continuous improvement and respect for people. This philosophy is based on two main principles: the elimination of waste and the pursuit of perfection.
Elimination of Waste
One of the key goals of the Toyota Production System is to eliminate waste in all its forms. This includes not just material waste but also waste in the form of time, effort, and resources. The goal is to make the production process as efficient as possible, with no steps that add no value to the customer.
Pursuit of Perfection
The second key principle of the Toyota Production System is the pursuit of perfection. This means that the company is constantly striving to improve its processes and products, to make them the best they can be. This focus on continuous improvement is a core part of Toyota's culture and has helped the company stay ahead of its competitors.
The Four Key Elements of the Toyota Production System
The Toyota Production System is comprised of four key elements: just-in-time production, jidoka, the Toyota Production System production control system, and the total involvement of all employees.
Just-in-Time Production
Just-in-time production is a system where parts are produced and delivered just in time for assembly. This reduces the amount of inventory that needs to be stored, freeing up space and reducing the cost of holding inventory.
Jidoka
Jidoka is a system where the machines stop automatically when a problem occurs, preventing defects from being produced. This helps to identify and address problems early on, reducing the cost of fixing defects later in the production process.
Toyota Production System Production Control System
The Toyota Production System production control system is a system for managing production processes and ensuring that they run smoothly and efficiently. This includes monitoring production processes in real-time and making adjustments as necessary to keep them running smoothly.
Total Involvement of All Employees
The final key element of the Toyota Production System is the total involvement of all employees. This means that every employee has a role to play in the production process and is encouraged to contribute their ideas and suggestions for improvement. This creates a culture of continuous improvement and encourages innovation at all levels of the organization.
Toyota has continued to grow since introducing the TPS.
Applying the Toyota Production System to Other Industries
The principles and practices of the Toyota Production System can be applied to other industries to improve efficiency, quality, and customer satisfaction. By focusing on the elimination of waste, the pursuit of perfection, just-in-time production, jidoka, and the total involvement of all employees, other companies can achieve the same level of success and innovation as Toyota.
Case Study: Applying the Toyota Production System to the Healthcare Industry
The healthcare industry can benefit greatly from the principles of the Toyota Production System. By focusing on the elimination of waste, the pursuit of perfection, just-in-time production, jidoka, and the total involvement of all employees, healthcare providers can improve patient care, reduce costs, and increase efficiency.
One example of how the Toyota Production System has been applied to the healthcare industry is at the Virginia Mason Medical Center in Seattle, Washington

Classroom Exercise: Implementing the Toyota Production System
Objective: To give students a hands-on experience in implementing the principles and practices of the Toyota Production System.
Materials:
- Whiteboard or chalkboard
- Markers or chalk
- Flip chart or poster paper
- Sticky notes
- Timer
Instructions:
- Divide the class into groups of 4 to 5 students each.
- Assign each group a simple production process to improve, such as making a sandwich or folding a piece of paper into an origami shape.
- Have each group map out their production process using a whiteboard, flip chart, or poster paper.
- Have each group identify the waste in their production process using sticky notes. Waste can include steps that add no value to the customer, waiting time, overproduction, overprocessing, excess inventory, unnecessary motion, defects, unused talent, and unused creativity.
- Have each group implement just-in-time production by delivering the inputs for each step of the production process only when they are needed.
- Have each group implement jidoka by having the machine stop automatically when a problem occurs, and only restarting it once the problem has been fixed.
- Have each group implement the Toyota Production System production control system by monitoring their production process in real-time and making adjustments as necessary to keep it running smoothly.
- Have each group encourage the total involvement of all team members by involving everyone in the production process and encouraging them to contribute their ideas and suggestions for improvement.
- Have each group present their improved production process to the class, highlighting the waste they eliminated, the steps they took to implement just-in-time production, jidoka, the Toyota Production System production control system, and the total involvement of all team members.
- Set a timer for 5 minutes and have each group work on further improving their production process.
- Have each group present their final improved production process to the class, comparing it to their initial process and highlighting the improvements they made.
- Facilitate a class discussion on the principles and practices of the Toyota Production System and how they can be applied to other industries.
This exercise will give students a hands-on experience in implementing the principles and practices of the Toyota Production System and help them understand how these principles can be applied to improve efficiency, quality, and customer satisfaction.
