What is Toyota Lean Management?

Toyota Lean Management focuses on eliminating waste in all operations, which is most effectively achieved by establishing a strong foundation of core values and principles. This foundation supports various repeatable management practices, such as organizing workspaces, building consistent procedures, and implementing other useful management techniques that successfully eliminate waste. The main goal of TLM is to create a product of great quality at the lowest possible cost and in the shortest time.

Key Principles of Toyota Lean Management

Lean principles, which are widely adopted in manufacturing and service organizations today, are largely based on studies of Toyota's Production System (TPS) from the 1980s. 

1. Value: Understanding Customer Needs

   The most important part of what you're making for your customers is the solution to their problem that they're willing to pay for. Anything you do that doesn't directly add value is considered waste and can be removed. 

2. Value Stream: Mapping the Process Flow

   Once you figure out what your customer finds most important, the next step is to analyze and map the value stream. This means identifying every action that contributes to the final product or service, and any steps that don't directly benefit the customer can be considered wasteful. The waste can be divided into two types: things that may be necessary but don't add value, and things that are not necessary at all. The latter should be eliminated, while the former should be minimized. Cutting down on unnecessary steps or processes can make sure your customers get exactly what they want while also lowering the cost of producing that product or service. 

3. Flow: Achieving Continuous Production

   Once you have a good understanding of your value stream, you need to make sure everything runs smoothly within your team, and this might take some time, as making a product or service often involves people from different areas working together. Sometimes things get stuck or interrupted, but by breaking down tasks into smaller pieces and visualizing how the work flows, you can easily spot and fix problems that slow things down.

4. Pull: Responding to Customer Demand

   Inventory, or having too much of a product that isn't sold yet, is often seen as a big problem in production systems. A "pull" system is a way to solve this problem by only making what is needed and work-in-process (WIP) items. This means that the right materials and information are available at the right time to keep the work flowing smoothly. This is also called "just-in-time" manufacturing. To create a pull-based system, start by figuring out what the customer needs and work your way backward through the production process. This way, you can make sure the products you make will meet the customer's needs.

5. Perfection: Striving for Continuous Improvement

   After you have completed all the previous steps and built your Lean management system, the fifth step of striving for perfection becomes the most important. Remember, nothing stays the same, and problems can pop up anywhere. That's why it's crucial to get everyone involved in finding ways to improve the process, no matter what their role is. Your company should be a place where people are always learning and finding ways to do things a little better every day.

Essential Tools and Techniques in Lean Management

Lean management by Toyota is all about eliminating waste and streamlining processes to optimize efficiency and to achieve this, there are several key tools and techniques that lean practitioners rely on. Here are a few of the most important ones: 

• 5S System

  Toyota's Lean Manufacturing approach includes a 5-step system called 5S to improve productivity, safety, efficiency, and employee satisfaction. This method improves the company's bottom line by organizing workspaces and eliminating clutter; here's what each step means:

  • Sort: Organize items in the workspace and remove unnecessary ones.
  • Set in Order: Arrange necessary items in a logical, accessible manner.
  • Shine: Regularly clean and maintain the workspace for optimal performance.
  • Standardize: Create a consistent, repeatable process for maintaining the workspace.
  • Sustain: Continuously review and improve the 5S system to ensure long-term success.

  Toyota Core Values

  Have you ever come across the phrase "there's no 'I' in team"? Lean principles are not just about finding areas for improvement, but also about creating a respectful work environment that motivates employees and contributes to their growth. Teamwork and collaboration are vital for achieving business objectives and refining the manufacturing process. Additionally, open communication, kindness, creativity, and practical thinking inspire employees to innovate and stay competitive.

• Lean Management Pillars

  A strong manufacturing process needs a solid foundation to support it. 

  Jut-in-Time
  The JIT approach highlights the significance of receiving materials only when they are needed and in the right quantities. By using this inventory management system, you can minimize waste, improve efficiency, and lower inventory costs. 

  Jidoka
  It focuses on empowering workers to stop production when a problem arises to make sure no defective products are made. By stopping production immediately, you reduce inventory costs and save warehouse space. This approach, which combines efficient production with timely delivery, helps your business progress toward its objectives.

• Kaizen

  Kaizen, which translates to “continuous improvement,” promotes the idea that no process is ever flawless and challenges should be welcomed. It involves making daily improvements to the process or product, making the operation more efficient than the day before. This continuous improvement results in significant cost and time savings, as well as improving the performance of the organization, team members, and individuals. 

• Gemba Walk

  The main idea of the Gemba Walk is for managers and leaders on every level to take regular walks around the shop floor and be involved in finding wasteful activities.

• Muda, Mura, and Muri

  In Lean thinking, there are three main types of waste:

  Muda: This refers to activities that don't add value for the customer. It's like doing extra work that doesn't make the product better or faster.

  Mura: This means unevenness in work. It's like having busy periods followed by slow periods, which makes it hard to plan and manage.

  Muri: This is about putting too much pressure on people or equipment. It's like asking someone to do too much, too fast, which can lead to mistakes and burnout.

  Finding these types of waste in your work processes can help you figure out where to focus your efforts to make things better.

• PDCA

  This iterative cycle is used for implementing improvements and ensuring quality. It involves planning the change, implementing it on a small scale, checking the results, and then taking action based on findings. 

  These are just a few of the many tools and techniques used in the Lean Management Toyota Production System, and implementing them can allow organizations to achieve significant improvements in efficiency, quality, and customer satisfaction. 

Benefits of Lean Management Implementation

Implementing a lean management system can bring several advantages to your business, including:

1. Improved Productivity: By getting rid of unnecessary steps and making things flow better, you can do more work with the same amount of resources.

2. Cost Savings: Cutting down on waste and extra stuff can help you save money that you can use to improve your business or offer better pricing for customers.

3. You Get Better Products: Lean Management focuses on making things right the first time. By using tools like mistake-proofing (poka-yoke) and just-in-time production, you can reduce errors and make better products or services.

4. Increased Customer Satisfaction: When you make things that customers want and need, they are more likely to be satisfied and keep coming back.

5. Your Employees Feel Valued: Lean Management encourages everyone to get involved in finding ways to improve things. This makes employees feel like they are part of the team and helps them grow.

Conclusion 

To get the most out of Lean Management, it's crucial to focus on what you can control within your own company. While things outside your business, like the economy, can affect you, it's always best to concentrate on improving your own processes and finding ways to do things better. This way, you're always working towards improvement, no matter what challenges you face. It's about taking responsibility and finding solutions, not making excuses.
