Yes, people called it an inventory reduction program when they first heard of it. “Just in time” is one of the main pillars in the TPS. “Just in time” ideally means “one-piece flow.” Inventory is the greatest waste in the process, and it hides many problems, such as quality problems, breakdown times, waiting waste, and more. Let’s get back to history. Prior to the 1970 oil crisis, very few people in the world know what Toyota was up to. The fact that it emerged stronger than ever while many of its competitors were quite battered made people take notice. People went to Japan to find out how Toyota had done this. What people found was that Toyota was doing something called “just in time.” In the West, this was interpreted as an inventory reduction program. As a result, it became known as the “just-in-time inventory” program. Nobody really believed inventory could be taken out of the whole value stream. Therefore, “just in time” came to mean “go beat the heck out of your suppliers.” The big three auto companies (Ford, General Motors, and Chrysler) had lots of power over their suppliers, and they became pretty expert at this tactic—to their eventual detriment. James P. Womack came forward with Lean Thinking in 1996 and helped many to see the whole value chain. He showed how waste clogs the system and how continuous improvement was needed to link all parts of the chain to customer demand. He explained his findings in plain English, but once again people didn’t hear. Lean might be an element of the larger strategy, but it is most likely to be relegated to plant and manufacturing work. As a result, one company after another has tried lean and failed. Many people believe that just-in-time inventory equals zero inventory. The ideal situation is one-piece flow, which can only be achieved through the use of a manufacturing cell. The inventory buffer exists, but it is rarely used. The Andon system includes a buffer. There is a safeguard in place to protect your customer. There is a buffer to prevent the entire manufacturing line from being shut down to rectify a problem. There is a buffer in place to prevent the breakdown of a vital manufacturing process. Just-in-time production is a manufacturing system that produces and delivers only what is required, only when it is required, and only in the amount required. The Toyota Production System is built on two pillars: JIT and jidoka. JIT is based on heijunka and consists of three operating elements: the pull system, takt time, and continuous flow.

Takt is a German word that means the speed or rhythm of something. Takt time is a number that helps make sure that the pace of making pacemakers matches the pace of selling them. One of the most important things to consider in lean manufacturing is takt time. This is the rate at which customers want a certain group of products to be produced by one step in the manufacturing process. Takt time is a number that tells us how much time we have to make each item that the customer wants. Takt time is the time available for manufacturing divided by the number of orders. In the 1930s, the German aviation industry started using Takt as a way to manage production. The concept was used a lot in Toyota during the 1950s, and by the late 1960s, most of the suppliers for Toyota also started using it. Every month, Toyota evaluates the speed of a process, and every 10 days they also do a check to make any necessary changes. Takt time helps make sure that supply and demand are in harmony. This is what makes a lean production system work and function well.

Takt time is calculated as the amount of manufacturing time that is available divided by the volume of orders. In the 1930s, the German aviation industry employed Takt for the first time as a production management tool. The idea was widely used within Toyota in the 1950s, and by the late 1960s, it had been adopted by the majority of the Toyota supplier base. Every month, Toyota assesses the takt for a process, with a modifying review occurring every 10 days. Takt time is used to properly balance supply and demand. It gives a lean production system its beating heart.

In order to cut costs during the economic downturn, many businesses are implementing abstinence policies. This could mean laying off workers and cutting some wages. In fact, those actions might only work for a short time.Unless the company implements a culture of continuous improvement and alters its method of operation, the situation may recur and become even worse. This brings us back to the purpose for which the Toyota production system was developed. Waste is anything that uses resources but offers the customer nothing in return. Most activities are waste, or "muda," and can be divided into two categories. Although type one muda does not provide value, it is inescapable given the production assets and technologies available today. An illustration would be checking welds for safety, that type we also call necessary non value-added activity. Type two muda does not add value and can be quickly eliminated. An illustration is a process in a process village with disconnected phases that may be swiftly converted into a cell where unnecessary material moves and inventory are no longer necessary. A very small portion of all value-stream activities truly generate value as perceived by the client. The most effective way to boost business performance is to stop doing the numerous unnecessary things.

The laboratory examination of a lubricant's characteristics, suspended impurities, and wear debris is known as oil analysis (OA). OA is carried out as part of regular predictive maintenance to deliver precise and useful data on lubricant and machine condition. Trends can be found by following the findings of oil analysis samples over the course of a certain machine. These trends can help avoid expensive repairs. Tribology is the study of wear in machinery. Tribologists frequently perform or interpret results from oil analyses. Oil analysis is a long-term program that, where relevant, can eventually be more predictive than any of the other technologies. It can take years for a plant's oil program to reach this level of sophistication and effectiveness. This book includes what all practitioners need to know to build an oil analysis program for their machine inspection. This book includes three real case studies and numerous industrial examples to improve machine reliability and enhance the condition monitoring program.

Lean healthcare is the practise of applying "lean" concepts to the healthcare industry in order to reduce waste, enhance patient outcomes, and lower costs. All employees of the firm, from clinicians to operations and administrative personnel, continuously work to identify areas of waste and eliminate anything that does not create value for patients using lean concepts in healthcare. In general, lean thinking is a set of concepts, strategies, principles, values and tools used to create and deliver the most value from the customer perspective while consuming the fewest resources and fully utilizing the knowledge and skills of people performing the work. If you visit Toyota assembly plants you can see how Toyota has put all the systems and supports staff in place to ensure that the production team members on the assembly line always have the parts and the necessary tools, they need to do their jobs. Trucks are not as important as patients, but Toyota arguably puts far more effort into supporting their front-line staff than many hospitals do. Toyota allows the team members to focus on their work and the truck in front of them, leading to better results and satisfaction for all.

Toyota doesn't just make high-quality products; they also have a process for making sure everything they do is high-quality. Next time you want to say Toyota isn't that great, think about how their way of doing things could help you make better quality products. Reliability is about having a product or service that can be trusted is really important for making customers happy. This means that the product will work the way the customer wants it to, and it will keep working well for a long time. Quality experts are basically saying that it is very important to focus on improving quality in all aspects of a business. They believe that businesses should prioritize quality in order to be successful. The more complicated the product is, the harder this task gets. Before World War II, the military, aerospace, and aircraft industries used the failure mode and effect analysis (FMEA) approach. Toyota then invented its production system after the war. FMEA has been around since the middle of the 20th century, especially in the aerospace and military industries. FMEA was made in the 1940s and used by the U.S The military works to find and fix problems in production before they happen. The method worked well, so NASA used it for different projects like Apollo and Voyager in the 1960s. Nowadays Six Sigma's project team use FMEA in the Analyze stage of DMAIC because extraordinary quality is not only designed into the product, it is designed into the development process itself. The DRBFM methodology was created by Tatsuhiko Yoshimura, who is an expert in quality and a professor at Kyushu University in Japan. Yoshimura understood that making changes without the right documents can cause design problems. He used the idea of preventing problems before they happen to come up with his own way of thinking called DRBFM.
