![]() However, post-war Japan was low on resources while America was not. Kiichiro Toyoda issued a challenge to his company to “catch up to America”. Ultimately, there are eight types of waste that the TPS addresses:ģ) Waste of overproduction (considered to be the largest waste) The small improvements in waste reduction are benefits to any corporation. The process must have enough flexibility that it does not overburden anyone to generate waste. This is done by eliminating inconsistency, which is also known as“design out” inconsistency. The most vital effects on process value delivery are accomplished by devising a process capable of fulfilling the required results in a smooth manner. TPS has always had primary objectives that it strived to meet such as designing out overburden and inconsistency while eliminating waste. It was Kiichiro who came up with techniques and methodologies that led to waste elimination between operations. Kiichiro Toyoda also set out to breathe life into the idea of eliminating waste within the workplace. Through the automatic loom, Sakichi improved both work efficiency and productivity. It could also form judgments on its own, making the invention revolutionary. The automatic loom automated completed processes that previously could only be performed manually. TPS can trace its roots back to the automatic loom created by Sakichi Toyoda. As the waste builds over time, it can even affect the management of a corporation. Furthermore, it’s believed that all elements of waste can combine with one another to create more waste. In other words, all excess is considered wasteful. In many cases, waste can show up in the workplace in the form of excess inventory, defective products, and unnecessary processing steps. The TPS system was modeled after the “Just-in-Time” concept that was developed by the founder of Toyota Motor Corporation, Toyoda. Over the years, the TPS has morphed and improved through the fires of trial and error in a bid to make the workplace a hyper-efficient environment. The TPS follows the philosophy of “the complete elimination of waste.” This philosophy is demonstrated in Toyota’s highly efficient production process. The Toyota Production System (TPS) is the epitome of efficiency in the workplace. The MIT researchers found that TPS was so much more effective and efficient than traditionalmass production that it represented a completely new paradigm and coined the term lean production to indicate this radically different approach to production.Image Source: Pixabay History of the Toyota Production System Widespread recognition of TPS as the model production system grew rapidly with the publication in 1990 of The Machine That Changed the World, the result of five years of research led by the Massachusetts Institute of Technology. Under Ohno’s leadership, JIT developed into a unique system of material and information flows to control overproduction. He decreed that Toyota operations would contain no excess inventory and that Toyota would strive to work in partnership with suppliers to level production. ![]() Kiichiro Toyoda, son of Sakichi and founder of the Toyota automobile business, developed the concept of JIT in the 1930s. Eventually, this simple concept found its way into every machine, every production line, and every Toyota operation. This enabled great improvements in quality and freed people to do more valuecreating work than simply monitoring machines for quality. ![]() Sakichi Toyoda, founder of the Toyota group of companies, invented the concept of jidoka in the early 20th Century by incorporating a device on his automatic looms that would stop the loom from operating whenever a thread broke. The concepts of just-in-time (JIT) and jidoka both have their roots in the prewar period. Outside Japan, dissemination began in earnest with the creation of the Toyota- General Motors joint venture-NUMMI-in California in 1984. Beginning in machining operations and spreading from there, Ohno led the development of TPS at Toyota throughout the 1950s and 1960s, and the dissemination to the supply base through the 1960s and 1970s. TPS is maintained and improved through iterations of standardized work and kaizen, following PDCA, or the scientific method.ĭevelopment of TPS is credited to Taiichi Ohno, Toyota’s chief of production in the post-WW II period. TPS is comprised of two pillars, just-in-time and jidoka, and often is illustrated with the “house” shown at right. The production system developed by Toyota Motor Corporation to provide best quality, lowest cost, and shortest lead time through the elimination of waste.
