The Toyota Production System, or TPS, is a widely-used and successful production system in manufacturing that focuses on reducing and eliminating waste, while producing quality products for consumers. The TPS model was developed by the Toyota Motor Corporation for their vehicle production system, but the principles and activities it encompasses can be applied to nearly any industry.
When discussing the TPS and its many features, it can be helpful to think of the system like a house. The “house” of the Toyota Production system is built upon a strong and stable foundation, has two main pillars, with the overarching goal of TPS as the tip of the house.
The pillars of the house are also considered the basis of Lean manufacturing. Turning concepts into practice
The pillars of TPS
The first main pillar is the idea of just-in-time manufacturing. This emphasizes three main practices: continuous flow, Takt time, and a pull system. The idea of JIT manufacturing is to implement a production method that emphasizes the minimization of waste and workers being able to operate efficiently. Instead of producing items as you have the materials, certain steps of the production phase shouldn’t start until an order trigger it.
A pull system, usually a Kanban method, is designed to signal when an action is supposed to happen. Implementing a Kanban system works to keep the factory from overproduction. Certain processes and steps in the manufacturing process will only begin when a worker receives a specific signal. By doing so, unnecessary inventory will not be created, and bottlenecks will be reduced.
Takt time, another strategy used in just-in-time manufacturing, ensures the rate of manufacturing between stations is even. The equation used to calculate Takt time is T = Ta÷ D. The T represents Takt time, Ta represents the total available production time, and D represents the rate of customer demand. By finding the Takt time, you will know how much time it should take to produce each product in order to meet customer demand.
The second pillar is Jidoka, often referred to as autonomation, meaning automation with human touch or human intelligence. This process essentially refers to the use of machines or equipment to alert workers of a problem with a process before more resources are wasted. TPS focuses largely on building a culture that emphasizes stopping to fix problems as they arise in order to get quality from the start.
A main principle of this is the idea that in the case of abnormalities, machines should stop, and workers should be notified of what went wrong. An example of this is a workplace using Andon lights. Andon lights are most often light posts with a green, yellow, and red that will change color when a problem arises in a manufacturing process. The visual signal will alert employees to an interruption and the issue can be addressed immediately. This uses both the machine detecting errors to alert the worker something needs to be fixed, a perfect example of automation with a human touch.
The pillars of the Toyota Production System are built upon a stable foundation of standardized work and continuous improvement. The goal of using the strategies of Toyota and Lean manufacturing, like Kanban, Takt time, and Andon lights, is to create high quality products at the lowest cost to the manufacturer with the shortest lead time. Eliminating wastes and ensuring the product will meet customers’ expectations are the name of the Lean manufacturing game.

What is Toyota production system just-in-time? ›
All adhere to the following principles of Just-in-Time to achieve synchronized production: 1) Only make what is needed by the customer, when it is needed, and in the amount needed; 2) Don't allow goods and information to be held up during production; 3) Make them at the pace at which they're sold.

Each of the five independent variables (5S variables) significantly affected the dependent variable prediction. Implication-The study found that implementing 5S in an organization should be seen as a full productivity system.
When did Toyota implement 5S? ›
5S is a core methodology to lean manufacturing which was first implemented in Toyota's Production System (TPS) in the 60s.
What are the 5 steps of the Toyota Production System? ›
- Sort (Seiri)• Straighten (Seiton)
- Shine (Seisou)• Standardize (Seiketsu)
- Sustain (sh*tsuke)• The Bonus S of 5S.
Toyota's Production System (TPS) is based on "lean" principles including a focus on the customer, continual improvement and quality through waste reduction, and tightly integrated upstream and down-stream processes as part of a lean value chain.
Why is the Toyota Production System successful? ›
Toyota is famous for its use of low-cost automation, combined with immaculately maintained machines. Investing in smaller, more flexible equipment where possible will greatly reduce the waste of inappropriate processing.
Is Toyota still behind in production? ›
Production is expected to be back to normal at all 14 plants in Japan from the start of the second shift on Wednesday, the company said in a statement. “It is our understanding that the malfunction of the system was not caused by a cyberattack. However, we will continue to investigate the cause,” Toyota (TM) said.
TPS is grounded on two main conceptual pillars: Just-in-time – meaning "Making only what is needed, only when it is needed, and only in the amount that is needed" Jidoka – (Autonomation) meaning "Automation with a human touch"
Do other companies use Toyota Production System? ›
Not only have Toyota's rivals such as Chrysler, Daimler, Ford, Honda, and General Motors developed TPS-like systems, organizations such as hospitals and postal services also have adopted its underlying rules, tools, and conventions to become more efficient.
How does Toyota use Kaizen? ›
Standardised work involves following procedures consistently and therefore employees can identify the problems promptly. Within the Toyota Production System, Kaizen humanises the workplace, empowering individual members to identify areas for improvement and suggest practical solutions.
What are the 5 principles of lean manufacturing? ›
The five lean principles are:
- Defining value.
- Value stream mapping.
- Creating flow.
- Establishing pull.
- Continuous improvement.
It include five words Seiri, Seiton, Seiso, Seiketsu and sh*tsuke, which means Sort, Set in order, Shine, Standardize and Sustain respectively.
What does the 5S model stand for? ›
The 5S pillars, Sort (Seiri), Set in Order (Seiton), Shine (Seiso), Standardize (Seiketsu), and Sustain (sh*tsuke), provide a methodology for organizing, cleaning, developing, and sustaining a productive work environment.
What is the origin of 5S Toyota? ›
The Japanese methodology 5S is depended on five various pillars: Seiri (Sort), Seiton (Set in order), Seiso (Shine), Seiketsu (Standardize) and sh*tsuke (Sustain). In past, 5S was known as the Toyota Production System, which was developed by Taiichi Ohno and Eiji Toyoda with Japanese industrial engineers in 1950.
