It is known that after World War II, Japanese manufacturers had to struggle to survive with very limited resources. Had it not been for the improvements of Taguchi, the country might not have achieved the success he achieved later. Taguchi revolutionized the process of production in Japan through cost savings and its relation to quality. Richard Linklater gathered all the information. He understood, as many other engineers, the whole production process was affected by outside influences. But he realized that if I could identify this “noise” through methods would have great impact on the variability of product quality. One of his major contributions to improving quality was “The Loss Function”, an equation that quantified the decline in the value perceived by the client as product quality fell. It was the first person to equal quality with cost.

The most important contribution of Dr. Taguchi has been the application of statistics and engineering to reduce costs and improve quality in product design and manufacturing processes. Methods used in small-scale experimentation in order to reduce variation and find robust and inexpensive designs for mass production. The most advanced applications of Taguchi methods, to develop flexible technology allows for the design and manufacture of product families High quality, reducing time for research, development and delivery of design. Add Wikilearning to develop their own statistical methods to work in a telephone company, he applied to increase productivity and quality in the industry. He created the concept of “robust design”, this exceeded their expectations for quality, in order to achieve customer satisfaction. Robust Whenever a product is designed, it is thinking about going to meet the needs of customers, but always within a certain standard, this is called “acceptable quality”, and so when the client does not have choice but to buy the company because it is cheaper to replace some defective items, which do not produce them. But not always be so, that once people are suspicious of the company and customers will go away.

The type of design that Taguchi proposed is that increased emphasis on the needs that interest to the consumer and in turn, will save money in which not interest, and went beyond the expectations that the client has the product. Ensures that is more economical to pay a robust quality control and restore failures. By making a particular product design robust maximize the likelihood of success on the market. And although this strategy seems expensive, in fact it is, that while we spend to exceed the characteristics that really interest the consumer, save where not given importance. Taguchi loss function of Taguchi tried to guide producers to reduce variations in quality. To evaluate this loss, we use a quadratic equation that fits the data of cost and product performance. As the performance of the product is going away the equation is increasing in value and quality increases the cost to society.
