The authors argue that this system can be applied to other industries, including healthcare, software development, and services.
The book is considered important for product managers and entrepreneurs because it provides a comprehensive understanding of the principles of lean production and how they can be applied to improve a business. The book provides a detailed explanation of the tools and techniques used in the lean production system, such as value stream mapping, kanban, and poka-yoke, which can be used to identify and eliminate waste, improve flow, and increase efficiency.
It also emphasizes the importance of continuous improvement and the role of the entire organization in driving change. This is particularly relevant for product managers and entrepreneurs who need to constantly improve their products and processes to stay competitive.
In summary, “The Machine That Changed the World” is an important book for product managers and entrepreneurs as it provides a comprehensive understanding of the principles of lean production, and how they can be applied to improve a business, by identifying and eliminating waste, improving flow, increasing efficiency, and emphasizing the importance of continuous improvement.
How did the TPS revolutionnized the world industry
The book explains that the TPS was developed by Taiichi Ohno, an engineer at Toyota, in the 1940s and 1950s. Ohno was tasked with improving efficiency and quality at Toyota’s factories, and he began experimenting with different methods and tools to achieve this goal. Over time, he developed a set of principles and practices that became known as the TPS. The lean production system, also known as the Toyota Production System (TPS), has led to significant improvements in efficiency and quality in the automobile industry through a combination of several key elements.
One of the key elements of the TPS is the focus on continuous improvement, or kaizen. This means that all employees, from the assembly line workers to the managers, are encouraged to identify and eliminate waste and improve efficiency in the process. This is achieved through a system of daily meetings, where employees are encouraged to identify problems and suggest solutions.
Another key element of the TPS is the emphasis on waste reduction, or muda. The TPS identifies seven types of waste: overproduction, waiting, unnecessary movement, excess inventory, overprocessing, unnecessary transportation, and defects. By identifying and eliminating these types of waste, the TPS helps increase efficiency and reduce costs.
The TPS also emphasizes the importance of flow, or the smooth movement of materials and information through the process. This is achieved through the use of tools such as kanban, which is a system for managing the flow of materials and information, and just-in-time (JIT) inventory management, which aims to reduce inventory levels and improve efficiency by ordering and producing materials just in time for use.
The TPS also places an emphasis on quality, or jishuken. This is achieved through the use of tools such as poka-yoke, which is a technique used to prevent errors and defects in the process, and total quality management (TQM), which is a management approach that focuses on quality in all aspects of the business, from product design to customer service.
Finally, the TPS emphasizes the importance of employee empowerment and training. This is achieved through the use of tools such as standardized work, which establishes consistent, efficient procedures for performing tasks, and visual management, which makes information about the process or operation visible to everyone.
By using these tools and techniques, the TPS helped Toyota achieve significant improvements in efficiency and quality in the automobile industry, such as reducing waste, increasing productivity, and improving customer satisfaction. The book explains that this system can be applied to other industries, including healthcare, software development, and services.
Tools and techniques
Here is a list of some of the tools and techniques described in “The Machine That Changed the World” and an explanation of how they are used and why they are useful for product managers and entrepreneurs:
- Value Stream Mapping: This is a tool used to map out the flow of materials and information in a process, from raw materials to finished product. It helps identify bottlenecks, delays, and areas of waste in the process. By understanding the flow of materials and information, product managers and entrepreneurs can identify opportunities to improve efficiency and reduce waste.
Examples:
- A product manager for a clothing company maps out the flow of materials and information from textile production to finished garments, identifying delays in the cutting and sewing stages.
- An entrepreneur in the food industry uses value stream mapping to understand the flow of ingredients and information from suppliers to finished products, identifying an opportunity to reduce waste by streamlining the packaging process.
- A product manager for a software development company maps out the flow of information and tasks from the initial idea to the final product, identifying bottlenecks in the testing and deployment stages.
- Kanban: This is a tool used to manage the flow of materials and information through a process. It uses visual cues, such as cards or boards, to indicate the status of a task and to signal when more materials or information is needed. Kanban helps product managers and entrepreneurs understand the flow of work and identify opportunities to improve efficiency and reduce waste.
Examples:
- A product manager for a manufacturing company uses kanban to manage the flow of materials and information through the assembly line, identifying delays and bottlenecks in the process.
- An entrepreneur in the construction industry uses kanban to manage the flow of materials and information on a building site, identifying an opportunity to reduce waste by ordering materials just in time.
- A product manager for a software development company uses kanban to manage the flow of tasks and information through the development process, identifying an opportunity to reduce delays by streamlining the testing process.
- Poka-Yoke: This is a technique used to prevent errors and defects in a process. It uses simple devices or procedures to detect and correct errors before they become a problem. Poka-Yoke helps product managers and entrepreneurs identify and eliminate sources of error and improve the quality of their products.
Examples:
- A product manager for a consumer electronics company uses poka-yoke to prevent errors in the assembly process, such as using color-coded parts to ensure the correct components are used.
- An entrepreneur in the medical industry uses poka-yoke to prevent errors in the manufacturing of surgical instruments, such as using a gauge to ensure the correct size is used.
- A product manager for a software development company uses poka-yoke to prevent errors in the coding process, such as using automated testing to ensure the code meets the requirements.
- Kaizen: Kaizen is a Japanese term for continuous improvement. It is an approach that focuses on making small, incremental improvements to processes, products, and equipment. Product managers and entrepreneurs can use kaizen to identify and eliminate waste, improve efficiency, and increase quality.
Examples:
- A product manager for a manufacturing company uses kaizen to continuously improve the efficiency of the assembly line, by making small changes to the process such as changing the layout of the machines.
- An entrepreneur in the service industry uses kaizen to improve the customer experience, by continuously making small changes to the service process such as reducing wait times or improving the quality of the products.
- A product manager for a software development company uses kaizen to improve the quality of the software, by making small changes to the development process such as automated testing or code reviews.
- TQM (Total Quality Management): TQM is a management approach that focuses on quality in all aspects of the business, from product design to customer service. TQM aims to involve all employees in the quality improvement process, and to continuously improve the quality of products and services. Product managers and entrepreneurs can use TQM to improve the quality of their products and services, and to increase customer satisfaction.
Examples:
- A product manager for a manufacturing company uses TQM to improve the quality of the products by involving all employees in the quality improvement process, from the design to the delivery.
- An entrepreneur in the service industry uses TQM to improve the quality of the service by involving all employees in the quality improvement process, from the initial contact with the customer to the follow-up.
- A product manager for a software development company uses TQM to improve the quality of the software by involving all employees in the quality improvement process, from the design to the deployment.
- JIT (Just-in-Time) : JIT is a inventory management strategy that aims to reduce inventory levels and improve efficiency by ordering and producing materials just in time for use. JIT helps product managers and entrepreneurs reduce waste by avoiding excess inventory and increasing efficiency by reducing lead times.
Examples:
- A product manager for a manufacturing company uses JIT to improve efficiency by ordering and producing materials just in time for use, reducing inventory levels and lead times.
- An entrepreneur in the retail industry uses JIT to improve efficiency by ordering and receiving products just in time for the demand, reducing inventory levels and costs.
- A product manager for a software development company uses JIT to improve efficiency by ordering and producing resources just in time for the development process, reducing delays and costs.
- Standardized Work: This tool is used to establish consistent, efficient procedures for performing tasks. By creating standardized procedures, product managers and entrepreneurs can ensure that tasks are performed consistently and efficiently, and that employees are properly trained to perform them.
Examples:
- A product manager for a manufacturing company uses standardized work to establish efficient procedures for assembling a product, reducing errors and increasing productivity.
- An entrepreneur in the service industry uses standardized work to establish consistent procedures for providing a service, ensuring that customers receive the same high-quality service every time.
- A product manager for a software development company uses standardized work to establish efficient procedures for testing and deploying software, reducing errors and increasing productivity.
- 5S: This is a system for organizing and maintaining a clean and efficient workplace. The five elements of 5S are Sort, Set in Order, Shine, Standardize, and Sustain. By implementing 5S, product managers and entrepreneurs can improve the efficiency and productivity of their workplaces, by reducing waste and increasing employee engagement.
Examples:
- A product manager for a manufacturing company uses 5S to organize and maintain a clean and efficient workplace, reducing waste and increasing productivity.
