How Toyota motors implemented TQM?
- 1 decade agoFavorite Answer
As defined by ISO:
"TQM is a management approach of an organization, centered on quality, based on the participation of all its members and aiming at long-term success through customer satisfaction, and benefits to all members of the organization and to society."
In Japanese, TQM comprises four process steps, namely:
1. Kaizen – Focuses on Continuous Process Improvement, to make processes visible, repeatable and measureable.
2. Atarimae Hinshitsu – Focuses on intangible effects on processes and ways to optimize and reduce their effects.
3. Kansei – Examining the way the user applies the product leads to improvement in the product itself.
4. Miryokuteki Hinshitsu – Broadens management concern beyond the immediate product.
TQM requires that the company maintain this quality standard in all aspects of its business. This requires ensuring that things are done right the first time and that defects and waste are eliminated from operations.
Although W. Edwards Deming is largely credited with igniting the quality revolution in Japan starting in 1946 and trying to bring it to the United States in the 1980s, Armand V. Feigenbaum was developing a similar set of principles at General Electric in the United States at around the same time. "Total Quality Control" was the key concept of Feigenbaum's 1951 book, Quality Control: Principles, Practice, and Administration, a book that was subsequently released in 1961 under the title, Total Quality Control (ISBN 0-07-020353-9). Joseph Juran, Philip B. Crosby, and Kaoru Ishikawa also contributed to the body of knowledge now known as TQM.
The American Society for Quality says that the term Total Quality Management was first used by the U.S. Naval Air Systems Command "to describe its Japanese-style management approach to quality improvement." This is consistent with the story that the United States Department of the Navy Personnel Research and Development Center began researching the use of statistical process control (SPC); the work of Juran, Crosby, and Ishikawa; and the philosophy of Deming to make performance improvements in 1984. This approach was first tested at the North Island Naval Aviation Depot.
In his paper, "The Making of TQM: History and Margins of the Hi(gh)-Story" from 1994, Xu claims that "Total Quality Control" is translated incorrectly from Japanese since there is no difference between the words "control" and "management" in Japanese. William Golimski refers to Koji Kobayashi, former CEO of NEC, being the first to use TQM, which he did during a speech when he got the Deming prize in 1974.
The History of TQM
This weekend I will be writing an article about software quality technique. Relevant to that will be a mention of TQM, a modern, hyper-managerial concept. I think of TQM in a much different way than the typical corporate bureaucrat so I thought today I would write a brief history of TQM to clear up some of the confusion that exists about it.
Originally what got TQM started was TPM "Total Productive Maintenance". It was invented by Toyota, not by W. Edwards Deming or by the U.S. Navy as many people think. In fact, Deming strongly disliked the TQM term that later was attached to his teachings by other people. Confused yet? Let's start at the beginning.
After the war the United States and Great Britain occupied Japan with around half a million troops and other personnel and ran the country as a military dictatorship. One of the civilians General MacArthur summoned to Japan to help run the conquered nation was a statistician named William Edwards Deming. Deming had a number of interesting ideas about improving manufacturing processes and his combination of fussy mathematics with personal pride and workmanship meshed well with the Japanese mentality. The Japanese developed a huge respect for Deming and today he is greatly revered there.
Deming's central thesis was that even though mass-produced items are supposed to be identical, in practice they will always vary from one another. Therefore, the industrial process should include a cycle for observing these variations and changing the process in order to reduce them. He called this cycle the "Shewhart Cycle" and it came to be known as Plan-Do-Check-Act (PDCA)--the "act" part of the cycle being where the process is changed to reflect quality checks.
This kind of thinking had a permanent influence on Japan's industrial development that long outlasted the American occupation which ended in 1952. Large Japanese industrial concerns tried to use the kinds of strategic thinking Deming taught in their operations. The most important of these efforts are what took place at Toyota in the late 1960s. At that time Toyota, a truck manufacturer, decided to begin producing passenger cars and they made a determined effort to appraise and improve their methods at a fundamental level. They succeeded phenomenonally at this and by 1980 were producing the highest quality automobiles in the world. They called their new methods "Total Productive Maintenance" or TPM.
What Toyota discovered was that the dominant cause of product defects was wear in the machines that made the parts. In turn this wear was caused by the accumulation of dirt and chips (metal shavings). The problem was that workers followed the basic American practice which was to operate a machine until it broke and only then call in an engineer to fix the machine. In some cases they would just throw the machine away and order a new one from America. This resulted in defective parts as the machine wore down and lack of productivity while the machine was waiting to be fixed or replaced. Another complication was that workers tended to move from machine to machine and often confusion resulted. How could systemic problems like this be fixed?
To solve the problems Toyota completely changed the way it operated its plants. First of all, they stopped moving workers around as much and assigned workers to have responsibility over individual machines. The next step was to require workers to keep special notebooks documenting their machine. Before this was done machines were more or less black boxes to the workers. The new way required the men to document not only how the machine operated, but its entire maintenance history and how it worked internally. Workers started taking apart their machines to learn about them and document their findings. Instead of hoarding mechanical knowledge in a few absentee engineers every worker started to have this kind of expertise.
The next step was to tackle the dirt. In the 1965 Toyota's factories looked like American factories: chips and dirt everywhere. They would change that. Since dirt was responsible for the wear that was causing defects it would be eliminated. They started on the outside by creating sweeping and cleaning regimens. Then they started regularly taking apart their machines to clean them. Finally they put their expertise to work and started designing special guards and covers to keep dirt and chips out of machines permanently.
The last step in the equation was systematic preventative maintenance. Part of their documentation efforts was to carefully study any irregularity in machine operation. For example, if a machine began to vibrate in the old days they would ignore it until the machine broke, like Americans. In the new way they would immediately stop any machine that was vibrating and take apart the machine to discover the cause. Because they now actually had started to learn how the machines worked internally this was possible. The worker (NOT an engineer) would then attempt to fix the problem. In some cases these procedures led Toyota to actually redesign and modify parts inside their tooling to improve it.
The results of these efforts are well-known: not only did Toyota start making the highest quality cars in the world but by 1980 they dominated the import market. Today Toyota is the most profitable car manufacturer in the world by a large margin.
With this kind of success other Japanese and even American manufacturers became interested in their methods. Perhaps, more significantly, so did the military. The US Navy began to develop what it called "Total Quality Management" around 1980 which was based on a collection of Japanese models, the most important of which was Toyota's TPM. By the late 80s Secretary of Defense Carlucci mandated that these ideas be adopted throughout the US armed forces. Corporate America followed like a little dog and TQM became mainstream.
Unfortunately most companies just pay lip service to concepts like this. They neither really understand what it is about nor do they have the will to make fundamental changes to the way they think and operate. For this reason if you go into most manufacturing plants even in Japan you will see the same old thing: dirt and chips everywhere and employees working machines they don't understand until they break.
What does this have to do with software anyway? Tomorrow I'll discuss it.Source(s): http://en.wikipedia.org/wiki/TQM#Origins http://johnchamberlain.com/diary/2005/diary_200501...
Try finding the Toyota engine that used in those Land Cruisers. It's darn near impossible. Those trucks were limited in production and like nearly every other Land Cruiser until recently, the Land Cruiser had it's own engine. There were no other Toyotas using the engine that the Land Cruisers used. It was a good engine but when it needed replacement, it was easier to find a Chevy 350. A Chevy engine? Yes. Chevy 350s are very reliable and they a dime a dozen since they were used in almost every vehicle Chevy made in the past. They were used for many decades and parts are pretty inexpensive for them. Think a powerhouse that costs as much as an old Bug to modify. They are that inexpensive. Finding an old Land Cruiser engine is a tedious task that could take months (even years to find); a 350 can be found at your nearest engine builder and in any junkyard. Chevys have had their issues but their V8s are pretty trouble-free. I love Toyotas but I do know that many of GMs engines were and still are extremely reliable. The 350 (like Toyotas 20/22R engines) is one of the most dependable engines ever built. Even us import guys know that.
