Summary of: Machine That Changed the World: The Story of Lean Production
By: James P. Womack

Introduction

Step into the fascinating world of the automotive industry and discover how it underwent an extraordinary transformation. In this summary of Machine That Changed the World by James P. Womack, you’ll explore the fascinating shift from traditional craft manufacturing to mass production and finally lean production. Delve into the story of Eiji Toyoda and his Toyota Production System, which laid the foundation for the lean production movement. Learn about the universal applicability of lean production and its benefits, such as better products at lower costs. This book summary will also take you through key aspects like automation, teamwork, communication, and leadership in the context of lean manufacturing.

Evolution of Auto Manufacturing

Craft manufacturing thrived in the automotive industry until the early 1900s when Henry Ford introduced mass production, which led to affordable cars. General Motors then dominated, but Toyota became a game-changer by implementing the Toyota Production System, leaning towards efficient production with worker input. Their approach has yielded better products, made quickly and at a lower cost.

Toyota’s Lean Philosophy Revolution

Toyota’s lean philosophy took the automobile industry by storm during the 1970s and ’80s, enabling the automaker to produce better cars in half the time than their Western counterparts. In 1984, GM partnered with Toyota to reopen an assembly plant in Fremont, California, and after training its workers in lean methods, the factory matched Toyota’s best plants in productivity and nearly in quality. The plant’s success demonstrated that Toyota’s lean philosophy could work anywhere, and this led to other North American plants making changes to improve their productivity and quality. By 1989, US automakers managed to narrow the gap with Japan in productivity and quality, while Japan maintained a lead in the luxury car market. Ford’s adoption of lean practices resulted in creating the world’s most efficient plant, located in Mexico. However, the European automakers’ defect-resolution process took longer than Toyota’s entire production process, resulting in inferior cars with more defects. The book summarizes Toyota’s Lean Philosophy as a vital tool for increasing productivity while reducing waste and emphasizes its role in revolutionizing the automobile industry globally.

Lean Production Secrets

Discover the secrets of lean production techniques to revolutionize your organization. From improved parts design to cross-training workers and emphasizing trust, find out how to increase efficiency and innovation.

The concept of lean production has revolutionized manufacturing and transformed companies around the world. This approach involves streamlining processes in order to increase efficiency and productivity while reducing waste. While lean plants, in general, tend to use automation and robots, this only accounts for one-third of their gains compared to mass manufacturing techniques. The other two-thirds come from enhanced parts design and improved organization and management processes. In this book, you’ll discover the secrets of lean production techniques, from cross-training workers to leveraging a culture of trust and continual improvement.

Four fundamental factors differentiate lean-production from mass-production design techniques. One of them is leadership, where lean leaders control the new car design process and bear ultimate responsibility for getting a new design to market on time and on budget. This approach differs from Western counterparts, who must negotiate each element along the way. Lean teams are also made up of specialists from across the organization, and each team commits to the entire design and product lifecycle. However, in the West, divided loyalties and career conflicts often lead to lower levels of commitment.

Communication is also critical in lean production, with design leaders bringing all internal stakeholders together to hammer out agreements and reach consensus. Unlike the US, projects start small in Japan, involving fewer people, and grow to include the views and opposition of stakeholders later in the game. Thus, Japanese companies experience fewer delays while negotiating compromises. Lastly, the “simultaneous development” advantage means that lean teams work together from the start, giving them a jump start in determining the necessary materials and equipment. As a result, Japanese automakers spend much less on R&D, yet file significantly more patents and bring more patented innovations to market than their American and European counterparts.

The idea of lean production also extends to the supply chain. While in the West a car assembly may rely on thousands of separate suppliers, in Japan, automakers only deal with a few hundred suppliers arranged in tiers. In Japan, suppliers work with automakers in long-term, mutually beneficial relationships that provide a basis for just-in-time parts delivery. Whether reducing costs or splitting benefits, these types of trusting relationships with suppliers allow parts to go directly into the assembly process, reducing time, costs, and floor space.

The book goes on to highlight how Western automakers moved closer to lean supply chain management by the end of the 1980s, but they failed to embrace full disclosure and information sharing to build the trust necessary for partnerships with suppliers. Unlike Western companies, Japanese suppliers work with automakers to reduce costs throughout the life of a contract and share benefits evenly. As you apply lean production secrets in your organization, you’ll have an edge in reducing costs, improving efficiency, and enhancing innovation.

Selling Cars like the Japanese

The Japanese automotive industry sales model is relationship-oriented, customer-centric and personalized. Car salespeople in Japan are known for their product knowledge and excellent service. Toyota, for instance, employs a sales force that starts right after college, undergoes intensive product training and sells cars throughout their entire careers. The salespeople work to establish long-term relationships with customers and their families, and losing a customer brings shame. Japanese dealerships regularly consult customers on design preferences. They also offer free repairs as long as the customer owns the car, and fast, flexible and lean production allows customers to order customized cars that are delivered within two weeks. In contrast, North American car dealers transact with customers, mainly selling one brand. The customers complain of adversarial interactions, information withholding, and gamesmanship, often wondering why the automaker never seeks dealer opinions or inputs. Salespeople usually have little knowledge of the products they sell.
