Abstract
Organizations need to respect standards in order to "do the right job", i.e. manufacturing their products or services in a way that customers will agree with. That is why the International Organization of Standardization (ISO) has been created, on 23 February 1947. Its headquarters are in Geneva, Switzerland. This non-governmental organization set standards that often are laws. Actually, there is a strong link between ISO and Governments.
There are many sorts of ISO standards, for mechanical domain, language, environmental management or quality management. We will study in particular the quality management standards, which belongs to the ISO9000 family. ISO9000 is a family of standard used in quality management. Before 2000, it was divided into three parts ISO9001, 9002 and 9003 which were dealing with different specific aspects; but since 2000, all of these standards are comprised in one: ISO9001.
