Total Quality Management in Toyota
The production system of Toyota otherwise known as Toyota Management Systems (TMS) gives its adopters the ability to double their production in half the time, half the expense with half the problems and inventory in a fraction. TMS is no comparison to 'just' a production system. It is a three-innovation-combination model comprising of the policy of deployment (hoshin kanri), total quality management, and production just in time. Toyota did not establish these three innovations. The innovations command a powerful advantage in competition after the oil crisis that took place in 1973-74. Forty years later, the Japanese automaker is the leading in the United States while its competitors are still struggling to achieve the same. This has been possible because of the TQM systems it adopted.
By emphasizing on quality first and customer first corporate philosophy from the time of its establishment, Toyota scooped the prize for Deming Application in the year 1965 and the award for Japan Quality Control in the year 1970. This occurred after the establishment of Statistical Quality Control in 1949. It has performed Total Quality Management based on solid customer first principle and total participation. Additionally, from the time of the Creative Idea Suggestion System launch in 1951, suggestions have increased in number and the system has been established stable responses for the changes of interact with conscientious manufacturing (monozukuri) contributing considerably to the development of the company. As a result, the elementary concepts of problem solving, TQM, and continuous improvement through the spread of creative innovation became a core component of the company. This accounted for higher production quality levels after its adoption (Hino, 2006).
Just-in-time production
Toyota invented the Just-In-Time (JIT) philosophy after the Second World War. This was mainly based on the design of continuous manufacturing flow, which was a creation by Ford Henry in 1914. The production system of Ford was mainly focused on a grand scale mass production. Toyota adopted the system and emphasized on the need of eliminating the waste materials. Small portions of production motions needed by postwar market in Japan were small and fragmented. Toyota converted the long lines of production into cells of U-shape, cross trained workers to operate many machines and reduced times of changeover. This resulted in the slashing of time wasted and necessitated the work-in-process inventory. Toyota developed the popular signal cards (Kanban) system to complement their just-in-time cells. They functioned to link production cells, which were not integrated or co-located physically. The signal cards are also used for integrating the functions of suppliers and customers with almost similar needs of production (Bose, 2011).
Quality at the source
Toyota merged various quality checks into its production cells and operations. They got the inspiration from the ingenuity of Toyota managers and the Six Sigma that Japan imported after the war by the United States government. This made problem discovery and correction to be faster:
Successful checks: These checks mandate all individuals contributing to a process to evaluate the quality.
a) Previously performed work by others
b) Tools, materials or the equipment used in the process
Self-checks: these checks declare that all persons contributing to a process to evaluate their own work's quality.
Mistake proofing (Poka Yoke): This is critical for the significant conditions and steps in the processes that might be impractical or difficult for human inspection. Besides, this principle allows owners of the process to invent procedures and devices with quick display and ability to resolve problems to the management's satisfaction (Keen, 2007).
Hoshin kanri (policy deployment)
The policy of deployment also known as Hoshin Kanri is a management system in Japan that has been perfectly implemented by the decentralized decision-making management of Toyota. The policy of deployment is deeply rooted in the management by objectives of Drucker that were adapted by Japan in the context of TQM implementation. Toyota adopted the policy of deployment as a constituent of its TQM implementation during the early 1960s. The policy of deployment has various benefits although it is still not well-known to the western managers. The benefits include:
i. It allows for alignment of the organization by the management on significant targets for improvement that connect the current potential to performances in the future and customer satisfaction.
ii. It allows the company to have an exception in its management so that the focus of the company can mainly be towards strategy.
iii. It debates and substitutes the relatively slow methods of accounting management with capabilities of solving quality, delivery,...
