Total Quality Toyota

The economic profitability of a company it judges mainly in its sales and in the profits.

Nevertheless the financial criteria are not the only ones to determine the efficiency of a company. The quality in general from the point of view of the products which and on the management of the employees and the working conditions allows to reduce wastes of money and time. Indeed many errors can be avoided if we set up the real policy of total quality.

The total quality is an management approach of the quality which the objective is the obtaining of a very wide mobilization and implication of all the company to reach a perfect quality by reducing at most the wasting and by improving permanently the elements of release.

This approach bases on ISO 9004, standard which is of use as explanatory document to the standard ISO 9001.

This policy of total quality is a real state of mind which must be likened by all the employees to guarantee an optimal efficiency throughout the chain of value of the company.

Of the success of this implementation in the whole of the manufacturing process of a product, depends the quality of a product and its services.

Indeed the Total Quality Management (TQM) does not appear exclusively in the manufacturing process within the company. The total quality also applies to the supply as to the distribution or to the storage, etc.

Nevertheless it is necessary to realize that the TQM have a cost. Indeed to set up and especially has to maintain operational the TQM is very high especially within a big company. Companies have to determine, according to the financing that they assign to the quality, the economic importance of the quality. It is about a percentage in touch with the choices of the company.

It is really important to be able to guarantee the quality of products thanks to this principle because it is this quality which is presented to the final customer. This quality of products is completed by the quality reigning within the company.

It is true that in the company the total quality takes the shape of a multitude of daily actions realized on all the post offices of the company. It is necessary to know that the total quality took place in companies at the beginning of the 50’s and more particularly in Japan (TOYOTA).

It is in the TOYOTA Company that an engineer sets up the TPS.

The Toyota Production System is an integrated socio-technical system, developed by Toyota that comprises its management philosophy and practices. The TPS organizes manufacturing and logistics for the automobile manufacturer, including interaction with suppliers and customers.

The main objectives of the TPS are to design out overburden (muri) and inconsistency (mura), and to eliminate waste (muda). The most significant effects on process value delivery are achieved by designing a process capable of delivering the required results smoothly; by designing out "mura" (inconsistency). It is also crucial to ensure that the process is as flexible as necessary without stress or "muri" (overburden) since this generates "banasik" (waste). Finally the tactical improvements of waste reduction or the elimination of muda are very valuable. There are seven kinds of muda that are addressed in the TPS[2]:
