Unlocking the Power of Single Minute Exchange of Die (SMED)

In the ever-evolving world of manufacturing and beyond, time is a precious resource that can make or break a business’s success. To meet the demands of fast-paced markets and changing consumer needs, organizations sought ways to reduce downtime, increase flexibility, and enhance productivity. This quest for efficiency led to the development of a groundbreaking method known as Single Minute Exchange of Die (SMED). In this blog post, we will explore the origins of SMED, its significance in manufacturing, and its versatile applications in various industries beyond the factory floor.

1. The Founding of SMED:

SMED was pioneered by Shigeo Shingo, a renowned Japanese industrial engineer and a key figure in the development of the Toyota Production System (TPS). In the 1950s and 1960s, Shingo observed that excessive time was wasted during machine changeovers in manufacturing processes. Traditional changeover methods resulted in lengthy downtime, hindering the ability to produce different products quickly.

Shingo’s innovative approach to tackling this problem involved identifying and separating external setup tasks (those that can be performed while the machine is running) from internal setup tasks (those that require the machine to be stopped). By converting as many internal setup tasks to external ones, the time required for changeovers could be drastically reduced.

2. The Why Behind SMED:

The primary goal of SMED was to achieve rapid changeovers, reducing setup times to less than ten minutes or even a single minute, hence the name “Single Minute Exchange of Die.” By doing so, manufacturers could minimize production disruptions, accommodate smaller batch sizes, and enhance production flexibility. This not only reduced inventory costs but also enabled businesses to respond swiftly to customer demands and market changes.

3. The Global Influence of SMED:

The success of SMED in the Toyota Production System quickly caught the attention of the manufacturing world. As Japan’s manufacturing prowess gained international recognition, other companies sought to learn from their methodologies. Today, SMED is a fundamental Lean Manufacturing technique and has been widely adopted by manufacturers worldwide.

SMED’s influence extended beyond the factory walls and was incorporated into various Continuous Improvement methodologies such as Total Productive Maintenance (TPM) and Lean Six Sigma. By implementing SMED principles, organizations have transformed their operations, achieving higher efficiency, reduced waste, and improved overall competitiveness.

4. Adapting SMED beyond Manufacturing:

While SMED originated in manufacturing, its principles have proven adaptable to diverse industries and processes:

Learning from the Best: How Toyota Studied Ford’s Production System and Revolutionized the Automotive Industry

When Toyota first began producing automobiles in Japan in the 1930s, the company faced a number of challenges. Japan was a relatively small market for cars at the time, and Toyota lacked the scale and resources of established Western automakers. However, Toyota’s founder, Kiichiro Toyoda, was determined to create a world-class production system that would enable the company to compete on the global stage.

To achieve this goal, Toyoda turned to the pioneering work of Henry Ford and the Ford Motor Company in the United States. Ford had developed a revolutionary production system based on the principles of standardization, specialization, and mass production, which had helped him to create affordable cars for the masses. Toyota recognized the potential of Ford’s system and decided to send a team of engineers to the United States to study it firsthand.

The Toyota engineers were impressed by what they saw at Ford’s factories. They observed how Ford had broken down the production process into small, repetitive tasks that could be performed by unskilled workers, which allowed for high levels of efficiency and productivity. They also saw how Ford had developed a system of interchangeable parts and standardized components, which reduced waste and increased reliability.

However, the Toyota engineers also identified several limitations of Ford’s system. They noticed that it was highly inflexible, with production lines designed to produce one type of car at a time. This meant that if demand for a particular model changed, Ford would need to retool its factories, which was a costly and time-consuming process.

Toyota engineers returned to Japan and began to develop their own production system, which they called the Toyota Production System (TPS). TPS built upon the principles of standardization and specialization that Ford had pioneered, but added several key innovations that made it more flexible and adaptable to changing customer needs. One of these innovations was the use of small, multi-skilled teams of workers who could perform a variety of tasks and adjust their production processes on the fly.

Over time, Toyota refined and improved upon the TPS, turning it into a world-class production system that has been widely emulated by other manufacturers. Today, the Toyota Production System is recognized as a model of lean manufacturing, and has helped Toyota to become one of the world’s largest and most successful automakers.

Toyota’s early success was due in part to its willingness to learn from the best and adopt innovative practices from other industries and cultures. By studying Ford’s production system, Toyota was able to identify key principles that it could build upon and improve, ultimately creating a production system that has revolutionized the automotive industry.

Shining Light on Toyota’s Andon System: Empowering Quality and Continuous Improvement

This immediately halts the production line, preventing further defects and allowing supervisors and workers to address the problem swiftly.

The Role of Supervisors and Workers: Supervisors play a crucial role in the Andon system. When a light is triggered, they must respond promptly, assessing the situation and working closely with the affected workers to resolve the issue. Through effective communication and problem-solving, supervisors empower workers to actively participate in the continuous improvement process. This collaborative approach fosters a culture of accountability, learning, and innovation on the shop floor.

Impact on Toyota Vehicle Quality: The Andon system has had a profound impact on the quality of Toyota vehicles. By promptly addressing issues, defects are caught early in the production process, reducing waste and preventing faulty vehicles from reaching customers. This attention to detail and commitment to quality have significantly contributed to Toyota’s reputation for reliability and customer satisfaction.

Influence on Other Industries: Toyota’s Andon system has inspired numerous industries beyond automotive manufacturing. Organizations worldwide have adopted and adapted their principles, recognizing the power of visual management and real-time problem-solving.

Shigeo Shingo: The Mastermind Behind Toyota’s Manufacturing Revolution

Shigeo Shingo was a Japanese industrial engineer who played a key role in transforming Toyota into a manufacturing powerhouse. Shingo’s contributions to the development of the Toyota Production System (TPS) and the invention of the Single Minute Exchange of Die (SMED) technique have had a profound impact on the manufacturing industry worldwide.

Shingo’s work on the TPS helped Toyota to streamline its production processes, reduce waste, and increase efficiency. He emphasized the importance of continuous improvement, or Kaizen, and introduced the concept of Just-In-Time (JIT) manufacturing, which involves producing only what is needed, when it is needed, and in the quantity needed.

Shigeo Shingo designed the Single Minute Exchange of Die (SMED) technique to address the issue of long changeover times in manufacturing. Changeover time refers to the time it takes to switch a production line from producing one product to another. In the past, changeover times in manufacturing could take several hours or even days, during which the production line would be idle.

Shingo recognized that long changeover times were a major source of waste in manufacturing, and set out to develop a way to reduce them. His goal was to reduce changeover times to less than ten minutes, which is why he called it the “Single Minute Exchange of Die.”

Shingo’s SMED technique involved analyzing every step of the changeover process, eliminating any non-essential steps, and streamlining the remaining steps to make them as efficient as possible. This involved using tools such as checklists, visual aids, and standard operating procedures to ensure that each step was carried out quickly and accurately.

The impact of SMED on Toyota’s manufacturing efficiency was significant. By reducing changeover times, Toyota was able to produce smaller batches of products, which reduced inventory levels and enabled the company to respond more quickly to changing customer demands. This allowed Toyota to achieve a level of flexibility and agility that was previously unheard of in the manufacturing industry.

SMED also helped Toyota to reduce costs by minimizing downtime and increasing production capacity. By reducing the time it took to switch production from one product to another, Toyota was able to produce more products in less time, which increased its overall output and profitability.

Shingo designed SMED to address the issue of long changeover times in manufacturing, which was a major source of waste and inefficiency. His technique helped Toyota to reduce changeover times to less than ten minutes, which improved the company’s manufacturing efficiency, flexibility, and profitability.

Shigeo Shingo did teach SMED to other non-Japanese companies as a consultant. He was highly sought after as a consultant by companies all over the world who were interested in improving their manufacturing processes.

Shingo’s consulting work was highly successful, and many companies were able to benefit from his expertise in implementing the SMED technique. Some of the companies that he worked with included Ford, General Motors, and Harley-Davidson, among others.

For example, when Ford Motor Company implemented SMED at one of its manufacturing plants in the 1980s, it was able to reduce changeover times from several hours to less than 20 minutes. This led to a significant increase in production capacity and efficiency, as well as a reduction in costs.

Similarly, when Harley-Davidson implemented SMED at one of its manufacturing plants in the 1990s, it was able to reduce changeover times by 75%, which led to a significant increase in production efficiency and flexibility.

Shigeo Shingo’s consulting work with non-Japanese companies was highly successful, and many companies were able to benefit from his expertise in implementing the SMED technique. His contributions to the field of lean manufacturing and continuous improvement continue to be highly regarded and studied by manufacturers all over the world.
