The Toyota Production System is really a Business System

“Greatness requires time and fortitude” – FitzGerald

The Toyota Production System (TPS)

TPS uses time, aggressive focus, and solid management to become the best methodology for running a business.

The advantages today for companies that want to emulate the best practices of the TPS are numerous. There have been books written and presentations galore about what Toyota has done.  This almost highlights the disadvantages companies have today to emulate the TPS.  TPS is not something you learn about by studying but by living.

Toyota operates their company in a unique way that is not easily replicated. Sometimes the only way to internalize a methodology is to go through the process of failure, rework, agony, belief. Let’s go through a brief overview of what you would need to do today to march towards Toyota’s System.

Toyota has a culture that was built on actions. When Toyota says they respect their employees, they empower them and employ them for life. Those are two very large commitments. Toyota could not achieve what they have achieved today without making those two commitments. Toyota enshrines their commitments in what they refer to as guiding principles:

  • Contribute to society
  • Put the customer first and the company second
  • Show respect for all people
  • Know your business from the ground up
  • Get your hands dirty
  • Work hard and with discipline
  • Work as a team
  • Build in quality
  • Continually improve toward a vision

Some of these commitments are focused on employees, some on the business, and the rest on management. Think of all the problems companies have because they do not put the customer first and the company second. Look at your own company and see if your commitments come close to matching Toyota’s. Without a very close alignment, moving towards the TPS may not be the best strategy.

You can never achieve TPS and neither can Toyota.  Make your own TPS, it is a constant strive for perfection.  Your perfection is different than Toyota’s perfection.  You will start to build your own companies System or Production System. No one can successfully document the TPS because it is ever changing. It is changing to create a competitive advantage for Toyota. Your business must change to create a competitive advantage for you.  Toyota assembles supplier parts into an automobile. Unless you have the same business model you should create your own system.

Core Competencies

What do you RD&P (Research Design and Production)?  Here are some things to think about:

  • Does that part give you a competitive advantage?
  • Are you the best at cost controls?
  • Is the total expense of RD&P acceptable?
  • Is it important that competitors not have this capability?
  • Are you concerned about delivery metrics?
  • Is finger pointing a concern?

If your supplier has a greater potential to remove costs from the part, it may be time to consider a supplier relationship.  Toyota outsources about 70% of their parts.

Steps to build your System:

  • Guiding Principles/Your Company Principles
  • Rigorously follow your Guiding Principles and Company Principles. This creates a culture that brings rich benefits and only comes with time.

The TPS is what Toyota has come up with after 60 years of progress.

TPS is a methodology for the whole company to live. Fujio Cho, who was the president of Toyota starting in 1999, attempted to write a book describing TPS. This effort was doomed from the start because TPS is not static (see the last guiding principal). A business cannot just build TPS.

Each step towards your own vision of TPS drives quantifiable value into your business.

14 Toyota Way Principles

It makes sense to review the 14 Toyota Way Principles as stated in Liker, Jeffery K. (2004) The Toyota Way, Page 37 (First sentence by Liker; other content FitzGerald):

  1. Base your management decisions on a long-term philosophy, even at the expense of short-term financial goals. A great leader marches towards a vision. There will be ups and downs on that road but the vision will come closer to reality. When you decide to forsake short-term performance for the benefits of long-term gain you may be surprised about the response of your shareholders.
  2.  Create continuous process flow to bring problems to the surface. Continuous flow is the perfect state. Continuous Improvement is the method needed to march in that direction. Every company should push to create continuous flow.
  3. Use pull systems to avoid overproduction. The first tug in a pull system comes from the customer. This is Build to Order. Build to Order means that you are not overproducing.
  4. Level out the workload. Takt Time is the production line heartbeat. It is simply the rate of production. As an example let’s say Takt time is one minute. That means a product or service is delivered every minute. That also means that every step in the process completes within a minute. Some processes may only take 30 seconds. The concept of leveling out the workload is to even out the workload so ideally all processes take about a minute. There are some cases where this may not be true.
  5. Build a culture of stopping to fix problems, to get quality right the first time.This concept is all about quality and perfection and is based on a culture. It must be okay for anybody to stop an assembly line in order to highlight a quality issue. If this is done smartly, with a strategy, you will be able to stop the process you are working on without immediately shutting down the whole assembly line. Every production line has problems, the goal should be to surface those problems and address them.
  6. Standardized tasks are the foundation for continuous improvement and employee empowerment. The goal of a Standardized Task is not to beat up an operator for not following it but to use it as the starting point of a Continuous Improvement program. The documentation of a Standardized Task is owned by the process operator. It should be posted and followed. It is what is improved in Continuous Improvement.
  7. Use visual control so no problems are hidden. Visual Control is simply a way to see if there is a problem. It could be something as simple as an outline of tools on a pegboard all the way to a tray of parts or data that if not completely used signals a problem.
  8. Use only reliable, thoroughly tested technology that serves your people and processes. People are your company’s most adaptable tool.  Verify that technology integrates well into your people system.
  9. Grow leaders who thoroughly understand the work, live the philosophy, and teach it to others. Leaders should have a firm understanding of where and what the value the company is adding to the product or service. Leaders should foster teamwork and an environment of Continuous Improvement. Leaders should walk the processes that add value.
  10. Develop exceptional people and teams who follow your company’s philosophy. Regard employees as part of the company team and make an effort to grow them. This can be through taking classes, teaching classes, presenting to management, etc. Your company will grow through the growth of your employees.
  11. Respect your extended network of partners and suppliers by challenging them and helping them improve. Partners and Suppliers become more and more important as you become Lean. If you have a pull system then ideally it will connect with a supplier or partners pull system. Toyota financially invests in their suppliers with money and employees to support the supplier’s successful integration with Toyota.
  12. Go and see for yourself to thoroughly understand the situation. This has two very important components. First, if a problem is found then those working on the problem need to go and see the problem for themselves. Second, management must periodically walk the processes where the company is adding value for their customers. This is the most important thing a company does and management should be very familiar with it.
  13. Make decisions slowly by consensus, thoroughly considering all options; implement decisions rapidly. This is how Toyota operates. Every company has their own decision-making process. It may be time to rethink how decisions are made. Consider this just an example.  However, decide slowly and act quickly is a good option.
  14. Become a learning organization through relentless reflection and continuous improvement. The most important output of a Continuous Improvement program is the creation of a learning organization. Think about the importance of having a learning organization.

It would be a good exercise to build your own business principles.

TPS uses Lean Six Sigma throughout the organization starting with managing customers and ending with delivering them an automobile. TPS includes:

  • The Production System
  • An “aggressive sales” program
  • The finance system which allows them to obtain capital for large projects like a new factory
  • A supplier system which they rely on for design prowess and on-time deliveries

Every business has their list of critical systems, both internal and external, whose efficiency directly benefits the business. Toyota’s strategy is to integrate tightly to every strategic system, whether internal or external.
